Casio Oceanus OCW-S100-1AJF Review

Casio is not so well known for their top-end watches, even though they do create some expensive limited edition models. However, the Casio Oceanus OCW-S100-1AJF is a watch that rivals the likes of the Seiko Grande or similar dress watches.

It has a stunning black dial with blue accented hour markers as well as a blue and white second hand that really stands out. Add to that the Titanium case and band, Sapphire crystal, and Casio’s Multi Band time-keeping along with their Tough Solar movement and you have yourself a dress watch you will be hand down to future generations!

The Dial

The dial of the Oceanus screams class from the word “go”. It’s clean black dial, which keep in mind is also hiding the solar movement behind, works extremely well with the applied blue accented hour markers. With a double marker at 12 o’clock, of course!

The blue accents are continued in various locations such as the surround to the large date window at 3 o’clock and also around the dial’s edge against the bezel.

The hands are dress standard sword shape, with lume generously applied. The second hand, long and slim, has a base colored blue to match the rest of the accents. Note that the Oceanus logo is also the same color.

The minute train is placed at a sharp angle leading up to the crystal, which is a curved, anti-reflective sapphire that provides outstanding viewing angles all-around. There is also a ring of city codes that are used to set the time – which uses the atomic clock radio signal to set automatically. Courtesy of Casio’s Wave Ceptor / Multi Band 6 technology.

The Case & Bezel

Casio have used a stunning lightweight titanium on this watch which weighs in at a measly 90g. So, it is very light on the wrist.

Not only that, but the refined Japanese Zaratsu polish of the bezel, which is combined everywhere with fine-brushed elements, makes for a stunning overall look.

There are decent, but not overly large crown guards on the side, along with an extra button at 4 o’clock which is used in conjunction with the crown for time-setting and atomic functions.

The Titanium Band

The Casio Oceanus band is a fairly standard style solid linked titanium that is easy to adjust to your wrist. It has removable links and extra half-links, along with a couple of fine-adjustments on the fold-over clasp.

The only major beef with the band people seem to have is it’s permanence. That is, you can’t replace it for another strap you might like better – or just for a change of scene. So, if you don’t like the band, or tire or it, bad luck!

The Technology: Solar, Atomic Time-keeping

It is worth noting that you are not just getting a stunning looking dress watch with the Oceanus. You are also getting some of Casio’s finest watch technology.

First you get a Tough movement, which means that it is protected internally to reduce any issues from hits or drops.

On top of that, you get their solar technology which charges on almost any sort of light and means you don’t have to worry about your battery.

The Atomic time-keeping is also a plus, as it means you can auto-adjust your time and set it when you change time-zones. They have 29 different time-zones built in, along with daylight saving, and you can adjust it manually too.
