Casio Oceanus OCW-M800TBJ-1AJF, OCW-M800TGJ-7AJF and OCW-M800TLJ-5AJF
Posted by wristwatch on November 11, 2007
The new Casio Oceanus’ comes with two Casio’s main technologies, Tough Solar and Multiband 5. I guess one unique thing about the Oceanus series is that they do not have a crown, only four buttons to do the adjustments and settings. The main button is on the four o’clock position and is marked by the Oceanus logo imprinted on the button. These models feature a slightly larger bezel than the others in the Oceanus series, its to emphasize the sporty design.

Thanks for posting this Wristwatch. It looks like it adds a countdown timer which the M700 didn’t have, but removes the tide graph. Personally, the timer seems far more useful than a tide graph, so this is a plus.
Jon44 said
Could you double check the spec’s on the timer. From Ebay–Singapore, it says:
“# timer (set unit: 1 minutes, largest set: 60 minutes, it measures at 1 second unit”
whereas the description above says “set unit: 4 minutes” That seems like a big difference (if you could only set a countdown timer in 4 minute increments, wouldn’t really be that useful.)
If anyone can translate Japanese, I think it would also be interesting to understand how the countdown timer actually functions (something about “reverse subtraction” movement).
Jason said
4 minute increments seems like a dumb idea, so I have a hard time believing it. I would imagine that “reverse subtraction” means that it shows the initial time of the timer in reference to the 12 position, for instance, if you set it for 2 hours and 10 minutes, the hands would be at 2:10, then as you started the timer, the hands move counterclockwise, until they reach 12:00, which IMO, would be cool to watch!
Voicu said
Thanks for the post! US signal is from Colorado (from the Ebay description) and in Europe one in London and one in Frankfurt?
Which models are the ones with 5 motors (the ones in 900$ range in the US models) ?
Oceanus said
I believe every Oceanus without an LCD is 5 motors (600, 650, M700, M800, S1000, S1050). All of these are also 5-band radio reception, except the 600 and 650 series (which receive Japan and U.S., but not Europe).
Voicu said
Thanks! Great info! I was looking at the US site and the 5 motors are in the 900$ range and the others in the 550$ range so I was trying to find which is which (US vs Japan models).
Joe said
There are some wonderful bargains out there on eBay lately. I have an Oceanus Manta 1050 and absolutely love it, and decided to get all 3 variations of this watch. All 4 watches together added up to about the same price as one Citizen Attessa ($1200).
Jason said
Yep, good bargains on those Manta watches, but if you know the right place to go, you’ll get an Attessa for a lot less than $1200 (hint, and it’s not eBay). You might even be able to get a better deal on the Oceanus watches, but since there are a couple sellers on the Bay that have either no feedback, or have had some issues, you can get a good deal on them from those sellers…I guess it’s all in the timing.
You are also comparing a watch that has DLC with a watch that does not have DLC. If you look at the Attesa, for instance, the ATV53-2831, I believe the blue one without DLC, it will be more in line with the Oceanus prices.

Jon44 said
Jason:
Care to share? (i.e., better than Ebay places for Oceanus watches…)
Jason said
Jon, it really depends on the model. For instance, the OCW-300 I have currently, cost me $365US, but was the lowest price I could find. Ebay wanted like $450 for the same watch, however, one went about 2-3 days ago on the Bay for ~$120 or so (seller probably took a loss on that one).
Two sellers in Japan have a really good reputation for delivery, prices, and customer service. I have bought from both of them before. If it’s not on their site (generally, their sites are pretty basic), you can e-mail them (use the request form), and ask for a price on the model you are interested in.
Seiya-san: http://www.seiyajapan.com/
Katsu-san: http://www.higuchi-inc.com/index-e.html
Seiya has been out on bad health a few times now, but as of the 14th of November, he is back running his shop. I just purchased from him on the 14th. I also bought another watch from Katsu a few days before that, and am expecting that watch to show up any time now, probably by the end of the week.
Generally, it takes about 5 days to ship it from Japan to the US, which is amazing to me, considering you can order something in the US, to the US, and have it take up to 10-14 days!
Jason said
One other thing I should point out, is that Katsu requires you to pay in Japanese Yen (via Paypal), where as Seiya gives you a price in USD. The issue with paying in Yen using Paypal, is that Paypal charges a premium over the actual currency conversion, due to “possible fluctuations in the conversion” depending on the time the actual conversion takes place. So if you use http://www.xe.com, you can expect a certain percentage over that in actual cost to you in USD. Seems like it’s about a 5% upcharage in USD. You can see what the real cost to you will be by going into Paypal, and acting like you are going to pay someone in Japanese Yen, then the last step before you confirm, it tells you what the conversion rate is, and what USD will be taken from your account…
Jon44 said
Jason:
seems like your post prior to this one got lost (but thanks for the detailed info–just need previous post to make sense of it.)
Jason said
Hmm…so you see both 11 and 12 of mine? Those are the only two, prior to the one that you inquired about.
Oceanus said
Post 11 disappeared for awhile for some reason, but now it’s back. Thanks for the info, Jason.
Voicu said
Thanks for the info! I am waiting for an OCW-M800TBJ-1AJF from ebay, counting every second
.
Joe said
You will love it!
Voicu said
Watch arrived today. Brand spanking new, all tags and manuals and papers (in Japanese), packed carefully, very fast shipping and tracking number (got e-mail with tracking number in matter of hours after paying! and it arrived in USA in one day. Overall it took 5 day (due to Thanksgiving and Friday I wasn’t there when package came). Seller was kodai_2008.
Now that his feedback is higher more people are bidding and the prices and moving a little bit up (but not that much).
Model number is 5008 and manual is not available in English yet. I am trying to see which of the others manuals can be used (any info would be kindly appreciated).
Jon44 said
Joe or Voicu:
Could you describe specifically how the countdown function operates (e.g., which hands actually turn counter-clockwise…)
thanks,
jon
Voicu said
Jon44,
I am looking for a friend that knows Japanese. In the 4766 manual I haven’t seen any reference of the timer function. By repeatedly pressing C (mode) the day of the week hand moves: Day-TMR-DST-AL so I am guessing that by leaving it on TMR and then pressing B and D you will set the timer?
I hope I will get more info after I translate the manual. So far I adjusted the time, home time, checked reception (and I got a yes – in Southern California). I tried to set the alarm and the hands start spinning in various direction and it is not clear to me when it should stop (after a complete 24 hours rotation and then set the alarm time?).
I hope to get back with more info.
Voicu said
Information that I got by experiment NOT from manual (is in Japanese and I don’t read/speak it unfortunately). If someone has the manual please correct me if I’m wrong.
For timer:
1) Press “C” (mode)until small hand (3 o’clock subdial) reaches TMR. Now watch is in timer mode.
2) Press “A” (adjust) and this will move the hand around the 3 o’clock subdial in order to set the minutes for the countdown. The “60″ on the dial is same as “zero”.
3) Press “B” to start timer, “D” to stop/reset. In timer mode big seconds hands moves backwards, and the hand from 3 o’clock subdial also moves backward. 6 o’clock subdial hand does not move, 9 o’clock subdial hand continue to show the 24 hours. Hour and minutes hand continue to show time.
When 3 o’clock subdial hand reaches “60″ the alarm rings.
It is interesting to see the minutes hand moving forward and in the same time the big seconds moves backward.
4) Press again “C” (mode) to get the 3 o’clock subdial hand pointing to the day of the week = the watch is in time measuring mode again.
Hope this helps and works for your watch too.

The discussion on the ATV53 page concluded that the ATV53-2833 only has DLC on the buttons and maybe the bezel (ie, only the black parts). The band on the ATV53-2833 is duratect titanium, which should be the same as the S1050J. The S1050J has a sapphire bezel, which is even better than DLC.
gordonr said
Received an OCW-M800 the other day from Japan. It would be nice if an english language manual was available, but even without a proper manual it’s pretty easy to figure out. As someone else mentioned, the module 4766 is a pretty good baseline for most of the watch. The instuctions in post #21 above seems to describe the timer function, and the alarm function can be found in things like the module 4749 manual.
The watch has sycronized two nights in a row just by placing it in a west facing window. The location is in a wooded area near Boston, so it seems the radio performance is pretty good. The only thing I’m not wild about is the 21 mm band size.

My watch does not complete time-synch cycle. It goes into “ready” state when button A is pushed, but does not go into “work” state to comlete procedure. I live in NYC amongst tall bldgs, but I have Junghans and Invicta watches that can complete synching. Any ideas? Do I need to press A again or something? Many thanks, MILES IN NYC
gordonr said
Mine doesn’t do it every night, but probably 95% of the time when I place it in a window facing west. It has yet to sync just sitting on my nightstand. I’m located about 25 miles west of Boston in a wooded area with lots of tall trees around.
This is my first RC watch so my only point of comparison is the Oregon Scientific atomic sync clock on my nightstand. That syncs without issue better than half the time. However, even then it will go through 2 or 3 weeks sometimes where it won’t sync.
Joel said
My OCW-M800 sync’s every night on my night stand facing east from Anaheim, CA. I love this watch. Figured out the mode button and the thing is dead on accurate. Just point the 12:00 (Top) side of the watch towards Colorado, whichever direction that is for you and let it sit overnight. It will likely not sync during the day. It will try six times overnight starting at midnight.
D2 said
Gordonr,
In addition to what Joel said, make sure you watch is at least 2 feet away from any active electronic devices such as a powered on cell phone, cordless phone, alarm clock, etc. as they might be interfering with the watch’s signal reception. If your Oregon Scientific atomic clock is near your watch overnight, that might be the problem.

Voicu says that he got a watch from kodai_2008 on 26 November 2007. I think this seller also markets as yamato_2007 on e-Bay. Anybody had any experience ordering from any of the OCW-M800 line of watches from him?? Also, anyone know if these two sellers are, in fact, the same?
Joel said
I’ve read he’s the same seller and is reliable. People have gotten what they won.

Does anyone know he watch movement number off the back of the case on the OCW-M800 as you are supposed to be able to download the manual in english from the above website. I want to buy one if i can get the manual in english.
Thanks

The Closest Manual for the OCW-M800 Module 5008 in English That I found is the Module:5012 on http://world.casio.com/wat/download/en/manual/5012 only it doesnt have the countdown timer which you can get from the post # 21.
For timer:
1) Press “C” (mode)until small hand (3 o’clock subdial) reaches TMR. Now watch is in timer mode.
2) Press “A” (adjust) and this will move the hand around the 3 o’clock subdial in order to set the minutes for the countdown. The “60″ on the dial is same as “zero”.

Manual to use with the OCW-M800
Ok think I got it this time. Check out Module 5020 on http://world.casio.com/wat/download/en/manual/ it has the countdown timer and all the other features of the OCW-M800.
Hypernez said
I looked through almost all the manuals on their website in English for the OCW-M800 Module 5008
http://world.casio.com/wat/download/en/manual/
between Module 5022 and module 5020 It Covers everything This watch does. It looks like 5020 is made for just Japan Radio reception and 5022 is made for Japan and USA
Richard said
Like many others I got an OCW-800 through e-bay. I searched around and created a guide for myself. Some taken from here (thanks voicu), others from various manuals. I thought I’d share in case people still had issues. I’m not claiming to be original, more combining several sources into one. There’s more in the manual for ‘5022′ if you need to manually adjust your time which I didn’t include. I’m lucky enough to live in Denver, so about 50 miles from Fort Collins. My watch syncs even when it’s in a box in the basement
Buttons:
A B
C D
C is the ‘mode’ button. Each time you press it the status changes in the small sub-dial near the number 3. From ‘Timer’, to World Time mode (which also displays day light savings On / Off or ‘AT’ for automatic) and finally ‘Alarm’, before back to time-keeping. When the hand is pointing at the day of the week – it’s in time-keeping mode
To specify home city:
1. In time keeping mode, hold down ‘A’ for about 5 seconds until watch beeps twice (important – wait until it beeps twice)
2. Press ‘D’ to change city setting by moving the stopwatch second hand
3. Use ‘B’ to cycle between daylight savings being ‘OFF’ and ‘ON’ (see 3 o’clock dial)
4. Once you have the home city set, hit ‘A’
To manually receive time-signal, set home city first then, put the watch on a window sill with its ’12 o’clock’ facing out, and hold the ‘A’ button for about 2 seconds until the watch beeps once. The stop-watch second hand will move to ‘ready’ and later to ‘work’. The watch will then sit for up to 15 minutes while it searches for the signal, before beeping and setting the hands to local time.
To check the most recent manual, or automatic reception from the atomic clock, hit the ‘A’ key once and the stopwatch second hand will move to either ‘YES’ or ‘NO’. Press ‘A’ again to return to normal time-keeping, or wait 5 seconds and watch will do it automatically
To use World-Time
1. To go to world-time mode, hit the ‘C’ (mode) button until the sub-dial near the 3 points to either ‘On / Off / AT’ for DST.
2. Wait until hands have adjusted
3. Use the ‘D’ button to advance the stop-watch second hand to the city. One second after finishing hitting ‘D’ the time will change accordingly
4. If summer time on / off needs to be toggled, hold down the ‘A’ button for about 3 seconds to toggle.
5. Once done, hit the ‘C’ (mode) button until the sub-dial near the 3 points to the day of the week, indicating you’re back in time-mode
To Swap your World-Time city to your Home city
1. To go to world-time mode, hit the ‘C’ (mode) button until the sub-dial near the 3 points to either ‘On / Off’ for DST.
2. Wait until hands have adjusted
3. Press and hold the ‘B’ button for about 3 seconds until the watch beeps. Your home city and world-time cities have now switched
4. Once done, hit the ‘C’ (mode) button until the sub-dial near the 3 points to the day of the week, indicating you’re back in time-mode
To use stopwatch:
1) In time keeping mode hit ‘D’
2) Once hands are in position, hit ‘B’ to start stop watch.
3) To stop the stopwatch, press ‘B’ again, and ‘D’ to reset
4) Once finished with the stopwatch, press ‘D’ to get back to time mode.
5) (if you want to start timing quickly – in time keeping mode, hit ‘B’ to start watch – it may take up to a second, but it will get going – then follow instruction from (3) onwards)
To use timer:
1) Press “C” (mode)until small hand (3 o’clock subdial) reaches TMR. Now watch is in timer mode.
2) Press “A” and this will move the hand around the 3 o’clock subdial in order to set the minutes for the countdown. The “60″ on the dial is same as “zero”.
3) Press “B” to start timer, “D” to stop/reset. In timer mode stopwatch seconds hand moves backwards, and the hand from 3 o’clock subdial also moves backward. 6 o’clock sub-dial hand does not move, 9 o’clock subdial hand continue to show the 24 hours. Hour and minutes hand continue to show time.
4) When 3 o’clock subdial hand reaches “60″ the alarm rings.
5) Press again “C” (mode) to get the 3 o’clock subdial hand pointing to the day of the week and the watch is now in time measuring mode again.
To use alarm:
1. Press ‘C’ (mode) until small hand in 3 o’clock subdial reaches ‘AL’ for alarm. Watch is now in alarm mode.
2. Hold down ‘A’ for about 2 seconds until watch beeps, confirming it is in the setting mode
3. Wait until the hands come to a stop indicating the current alarm time
4. The stop watch second hand will move to ‘ON’ at this time
5. Use ‘D’ to move hands clockwise in one minute steps and ‘B’ to move counterclockwise in one minute steps
6. After setting alarm, hit ‘A’ to exit setting mode
7. Use the ‘A’ key to toggle the stop-watch second hand between ‘ON’ and ‘OFF’.
8. Once done, use the ‘C’ (mode) button to return to time-keeping mode
To toggle alarm on / off
1. Press ‘C’ (mode) until small hand in 3 o’clock subdial reaches ‘AL’ for alarm. Watch is now in alarm mode.
2. Use to ‘A’ key to toggle the stop-watch second hand between ‘ON’ and ‘OFF’
3. Once done, use the ‘C’ (mode) button to return to time-keeping mode

yes, it is but I prefer Richard’s easy to understand instructions as opposed to the overly complicated ones in the manual. Bravo, Richard.

Hi guys
Great forum! I am desperate to get hold of the Oceanus OCWM800TBA-1A. I live in the UK and can’t find it for sale anywhere. Also I have looked on ebay and can’t find that model for sale there either or with Seiya-san or Katsu-san. Has anyonegot any suggestions?

The japanese version is the same as the american version except the Japanese version says Casio under the word Oceanus on the face. I’ve only seen one of the american version on ebay but I see the japanese version all the time.

Hello,
I have ocw-m800 for about 6 month (boutght from ebay). Everything is OK, BUT (!) I have to frequently allign the hands to their home position (on average once in two weeks). They become missaligned by few “ticks”. The most prone one seems to be the day-of-the-week hand, but other including the minute and small-seconds were also affected.
Has anywane a similar experience?

Hi to everyone,
I just bought from Ebay Casio OCW-M800 and I can not figure out how do I make the big stopwatch secondhand go around by sec. It is stuck at 12 in normal position. Also how do I measure state of battery power? Does anyone know? Thanks a lot for explanation.
Martin
D2 said
Martin,
Did you watch come with a manual? Look at post #9 and a few others posts in this thread which talk watch manuals other people downloaded and used to understand this watches features. Enjoy your watch!
Martin said
Hi there,
Thanks for advisind me but I got these watch from Japan with japanese manual. From the articles above I got some info but I can get this as I am mentioning above about the stopwatch big second hand. It seems that it will not move by sec. in timing mode while the little hand shows the day. It always stays at 12oclock and only this little stopwatch hand is runing. It only goes arround in stopwatch mode and I thought it would be able to set in regular time mode though. My regular watches worked like this so I am sort of use to it and I thougt it should be like this that is way I am trying to work it out.
Thanks
Martin

Hi, Jan,
My OCW-S1000 has similar problem as yours. My home position does not correct sometimes(once a month), it automatically changes to 10 o’clock position i/o staying at 12 o’clock position.

I’m drooling over this watch, and I haven’t even seen it on my wrist yet. Does anyone know where I can find an Oceanus dealer in the Chicago area? The Oceanus website didn’t help me — one dealer no longer sells them and the other only had 2 models. I’d like to be able to compare it to a wide array of other Oceanus models. –thanks
Joel said
Dude, eBay…
kingracer said
If eBay let you see watches on your wrist before purchasing, that’d be a great suggestion. I might buy from an eBay seller, but I prefer doing the decision-making with physical watches on my wrist.
I’m still stumped finding a dealer near Chicago. You’d think Oceanus (Casio) would have more of a presence in the 3rd largest city in the US. Boggling!
