Expect nothing more than an elegant, tank-like built with a readily noticeable heft. Its handsome alternating of brushed and polished stainless steel surfaces gives the case a robust look to which the screw-in, signed crown adds. Smooth it goes in than many other high-priced dive watches but whether you get to use that helium-escape valve in an urban life is a big question. Still, it's a healthy dose of bling that throws the Rolex Submariner off balance to some extent.
In the space or on the sea, there's no denying OMEGA's legacy to the sport of sailing. The Omega Seamaster Professional Chronometer Men's Watch pays tribute to Omega's maritime legacy and comes up as an exquisite example of renowned watch-making building a heritage of an adventurous spirit.
The Omega Aqua Men's Watch features a distinctive blue dial, a date display (@ 3 o'clock) and a scratch-resistant sapphire crystal and the most interesting of all – A blue, ceramic unidirectional, rotating bezel! At 41 mm across, the stainless steel case houses a Co-Axial calibre 2500 and is fitted with a helium-escape valve @ 10. The bracelet is also stainless steel.
What makes a considerable chunk to be big fans of the Omega Men's Watch is its own merits and not because of the brand name Omega. Neither because it came on the big screen! One reason you fall in love with the Sea Master Professional chronometer is its ceramic bezel insert – an enhancement over the previous designs – and a plain, lacquered dial – which is also another enhancement. The whole package just turned pleasantly heftier than before, garnering more prestige as an astonishingly classic dive watch. The subtle and deep blue is far from being bright or distracting and is a comfortable choice for almost everywhere.
Visibility is top-notch and with Omega, you really don't need to mention it. It becomes possible due to the domed, anti-reflective sapphire crystal (invisible due to the applied ARC) covering the lacquered dial resembling a sea of liquid blue. The darker window blends seamlessly with the rest of the dial. Turn the watch over and the trademark Omega Dragon shows engraved on the case back.
Behind all that aesthetic excellence is the movement ticking the passage of time. The Omega-modified ETA2892 – what it lovingly calls the Calibre 2500 – is a certified chronometer movement using the co-axial escapement technology. It gives out 7 beats per second, so 25,200 bph per hour – the midway between low and high beat movements. Going a beat lower every second is 3600 beats less per hour or 86400 beats lesser per day, which reduces wear and tear of the movement's components (and therefore, maintenance intervals) greatly while lacking nothing in accuracy.
The caliber 2500 follows the paths of the calibre 1120 with two jewels added further to the ETA. The bi-directional, click-wheel automatic winding system benefits greatly from this. There are two each also in the escapement and in the mainspring barrel, the total count coming to 27. The power reserve is a good 44 hours; with typical single-barrelled automatics (of same size) that's almost maxing it out.
