Review: Oceanus 5-motor atomic solar chronometer dress watches
Oceanus is the high-end dress watch brand of Casio, the famous Japanese maker of digital instrument watches. Seiko and Citizen, the other two major Japanese watchmakers, long ago gave up on trying to sell digital watches to the public, leaving the market almost entirely to Casio. Oceanus is Casio’s attempt to compete seriously against Seiko and Citizen in the analog dress watch market, and to do so they knew they’d need to make watches that were both beautiful and compelling for the $500 and over price point.
Citizen has its extraordinary Eco-Drive movements that are driven by solar energy and never need a battery. Seiko has its very nifty Kinetic watches that are powered by the movement of a weighted pendulum that drives an electrical generator. Both use low power movements (often eschewing the power-sucking second hand) to make sure they have enough battery reserve to last many months without recharging.
I’m a big fan of the high-end Japanese dress watches because they have every advantage of the Swiss mechanicals with an order of magnitude better accuracy. So of course I’ve been excited about Oceanus watches since I first heard of them.
Unfortunately, there are no Oceanus retailers in my home city of San Diego. I’ve never considered buying watches online because you can’t tell from a photograph whether you’re going to like a particular watch and you won’t be able to size the bracelet yourself unless you happen to own specialty watch repair tools. But a recent road trip afforded me the opportunity to stop at an Oceanus retailer (Modern Watch Company in Glendale, CA, who were extraordinarily helpful) so I picked up a titanium Oceanus 5-motor, which is a completely analog chronometer that is nearly indistinguishable from a Swiss chronometer except by brand.
To compete in this price category (which is also populated by Swiss automatic mechanical watches) Oceanus decided to up the ante: They’d produce a dress watch equal to Seiko and Citizen in visual detail, include solar power to eliminate the battery, and produce higher accuracy than a typical Quartz movement by automatically synchronizing the time to the radio signal put out by the Fort Collins atomic clock. I’ve always wanted an atomic timekeeping watch, but every one I’d seen prior to Oceanus used a plastic case and frankly looked quite cheap despite the fact that they cost over $150. This signal can be received over most of North America, and by synchronizing to it nightly, the watch will always be exactly accurate simply by knowing which time zone it’s located in. Or, at least, that’s the theory.
It took a while to get the watch synced to the atomic clock signal. And by a while, I mean five days. Firstly, the signal is only receivable late at night. Secondly, your watch actually has to be somewhat facing the direction of Colorado and with a clear view through a window and sitting upright. Nothing else really works. Even with those conditions on my night stand, I only receive the sync signal about every third night. More than enough for accuracy, but it takes a long time just to determine if you’re ever going to get it. And in coastal areas, I was never able to receive it probably due to thermal ducting caused by the warm marine layer.
That said, the watch is still a reasonable watch, but it’s got one exceptionally incongruous problem:
The second hand isn’t a second hand.
It’s there, but it doesn’t indicate seconds. It indicates the time zone. The actual second hand is on a small dial at the 6-o’clock position. Why? Because moving a large second sweep hand takes a lot of power. The much smaller second hand below takes far less torque to move, which is important in a low-power watch mechanism run by a solar cell. To be fair, the new Citizen Eco-Drive’s do the same thing—I don’t like it in them either.
The small second hand as an additional complication is an innovation that some Swiss Chronometers have moved to in order to increase their power reserves. But those Swiss chronometers don’t also include a hand that confusingly looks exactly like a traditional second hand. So what you wind up with is a watch that appears to be stopped, unless you notice the tiny hand moving at the 6-o’clock position. Now, I know you can get used to it, but unless this was the only watch you were going to wear, I wouldn’t want to.
They use the hand to indicate the time zone (and a few other things) in the dual-time mode. It’s not a bad idea (they have to use something, after all) and I completely understand why they thought it was a good engineering trade-off, but going against the grain of a century of watch-making tradition for a nebulous feature that could have been solved another way is a really poor design decision. People expect devices to work according to standards. We don’t want to have to re-learn individual devices. We especially don’t want to have to explain to people what’s wrong with our brand new watch.
At the end of the day, I love the way the watch works, and the accuracy and ability to automatically change for daylight savings is awesome. If not for second hand issue, I’d say it’s the perfect watch.

Wrong. All chronographs I know of work in this manner.
Two Swiss examples are the Rolex Daytona and the Omega Seamaster Chronograph. Both use the “second hand” as the second hand for the chronograph, not regular time keeping. The regular time keeping second hand is relegated to a subdial. I also had a quartz Seiko watch that did this.
From Wikipedia, here are the normal conventions for hand use on a chronograph: “Analog chronographs show both time and stopwatch functions with analog hands. Typically the center hand will be used for stopwatch functions, while subdials may indicate seconds, stopwatch minutes and hours and (in some quartz chronographs) tenths or hundredths of a second.”

Casio is certainly keeping in line with tradition on this one. Perhaps you are just more used to non-chronograph watches…
Thanks for the review though. I want one of these!

I agree about the second hand. I have 2 Tag Heuer Automatic Chronos, a Tissot PRS200 Chrono, and a Swiss Army Chrono, and they all use the 6 oclock sub dial as a second hand.
I am really interested in getting one of these watches and as I would have to travel 400 miles to actually see one, I talked a Tourneau store into getting one here so I can look at it with no obligation to buy.
As I am very anal about exact time on my watch, I am curious to know how accurate the watch is if it does not recieve a radio signal for long periods of time. I will simply not remember to try and place this watch in a window to get time updated all of the time. Hopefully it’s quite accurate on it’s own.

ALL SOUNDS RATHER FUTURISTIC TO ME GR88

I bought the watch in July and from the moment I put it on, I have loved it! I always get the final word in any discussion as to who has the correct time on his watch. As was noted by others, I have to put the watch near my west facing front window to get the time signal each day. Ok, not a big deal. Otherwise, a good looking watch and a super watch to own. My favorite moment of the day is when I put the watch on in the morning and push the button to see if it correctly received the time signal. I get such a kick out of seeing it go to the Yes stop on the watch. (Yeah, I know, I gotta get a life)All in all, the best gift I ever gave myself!

I just bought this watch. It is on it’s way through the postal service. Can’t wait to receive it…

I have had one of these watches for over a year and love it. It will synchronize manually during the day, but it picks up the signal better and automatically at night, mainly because of changes in the ionosphere. In some locations, I have had to put it near a window (commercial building/hotel with steel construction), but in most cases I just place on on a dresser with my wallet, keys, etc. It is extremely accurate. I have several watches, so when I am not wearing my Oceanus I place it in a window for the day. It is then good for weeks if not months.

Good review. I agree with prior posts regarding most/all swiss mechanical chronographs have the second hand stationery. I own this watch and like it very much. I would prefer the right dial to stay in world time mode rather to bring both hands to the top while in time keeping mode. I also own a later model Oceanus which works in the way I prefer. the hands move a little slow while switching modes. Titanium on bracelet is a little too sensitive to scratching. Look at some of the higher end JDM only models if you want to get a truly impressive watch – ie OCW-S1240TC-1A.
