The Case: When creating the Dive watch, Cestrian reviewed the market to come up with the ideal dimensions and specifications. The results are a watch that measures in with a 42mm case and a thickness under 14mm; hitting that perfect sweet spot between form and function. The case is made out of 316L stainless steel, selected for its high resistance to corrosion and extreme temperatures. Finished with both high polish and brushed sections, it edges the line of being a capable tool watch while still being elegant enough for daily wear. Moving over to the side of the case, the sculpted crown guards serve to protect the crown from any accidental knocks. The screw-down crown at the 3 o'clock position is a must have feature in any dive watch. No detail was overlooked, as this component was turned into a key design feature with a 3D Cestrian shield logo embedded in black resign. As with all Cestrian watches, the watch has a sapphire crystal to provide scratch resistance. The sapphire glass has also been treated with Anti-Reflective coating to provide maximum legibility. A key component of any dive watch is the diving bezel. Special attention to detail was taken here to make sure the bezel action and grip are class leading. The uni-directional 120-click bezel allows for precision and reliability weather timing your dive or dinner in the oven. No shortcuts in material were taken as the bezel has been made from ceramic for its scratch resistance durability and longevity. The bezel also features a lume pip at the 12 o'clock position. Turning the watch over, you are treated to an exhibition case back allowing the wearer to see the inner workings of the watch, which is a rare feature on a 300M water resistant watch.
