The case is 316L surgical grade stainless steel and has a brushed finish throughout. The case measures 42mm and when figuring in the crown almost 46mm. The case has a very nice curvature at the lugs providing a nice comfortable fit on the wrist. The lug-to-lug measurement is just over 51mm and the case height measures a rather slim 11mm. However, the watch will not feel ultra small on the wrist and the combination of all the measurements, along with a 93 gram weight, should result in a quite comfortable fit on just about any wrist.
The case design is fairly standard, with no frills or branding on either side of the case. The crown is positioned at the 3 o’clock position. The case protected on each side by crown guards. The unsigned signed screw down crown measures around 7mm in diameter. The crown texture allows for easy grip and rotation and the action is extremely smooth with no significant grinding. There is an ever so slight amount of wobble when full extended in the time setting position. After thoroughly examining the Diver One Silicon, the wobble in the crown is the only aspect of concern; but not completely unexpected for a $200 dive watch.
The watch is equipped with a 120 click unidirectional rotating bezel. The bezel is quite firm with precise clicks and no significant play in either direction. I am pleased to see no play in the bezel, as that could be crucial in timing the various activities related to diving for which the model was created. The bezel insert is black aluminum and contains the necessary lume pip needed for diving or activities in darkened conditions. The watches, fitted with an anti-reflective (AR) coated sapphire crystal, combined with the firm bezel, are features not often found on a $200 dive watch.
The dial opening measures around 32mm revealing a nice matte black dial. The dial contains some features also not found often on watches in its price category. All of the primary dial markers are applied and contain adequate amounts of lume. The high polished handset finish corresponds with the high polished outline of the applied hour markers. The handset (including the second hand) contains adequate amounts of lume as well. A white date window, positioned at the 3 o’clock position on the dial, is of good size and quite legible. The dial layout is quite clean and legible overall with limited branding. The watch design is an affordable dive instrument, however, the high polished feature of the dial markers and hands add a bit of flair making the watch appropriate for other social settings as well.
