TVS Omega Ocean Universe Diving Watch features the exclusive Cal. 8900 movement, allowing for quick adjustment of the hour hand and date. It is equipped with a dual T shock absorber and a perfectly sized 43.5mm case that exudes stability and sophistication. The separate design uses fluorine and is stylishly lightweight, made from 316 stainless steel. The watch features a unidirectional rotating bezel and a sapphire crystal glass. It has a screw down stainless steel crown and comes with a stainless steel original folding clasp.First and foremost, this is a diving watch, so it has all the essential features that a diving watch should have: impressive luminescence, deep water resistance, a helium escape valve, and underwater timing functionality. However, what I find most notable about this watch is the quality of feel once you wear it. The sensation is different from that of a luxury watch; the Ocean Universe fits comfortably and naturally on the wrist. The synergy between the wrist and the watch increases rapidly the moment you put it on. A good watch requires not only perfect design by a skilled designer but also high quality materials to reflect its value. So rest assured in your purchase; it s an excellent choice for gifts or personal use.
