Swiss Military by Chrono SMA34106.05 The Swiss Military by Chrono men’s watch SMA34106.05 is a companion for diving enthusiasts from the Automatic Diver’s Watch 42mm 20ATM series. It’s the perfect choice if you’re looking for a diver’s watch with water resistance up to 20 atm and a look inspired by diving. The watch features a silver case made of stainless steel, which stands out as a real eye-catcher thanks to its matte and polished finish. The round case is 42 mm wide and 14 mm high and, depending on individual taste, complements nearly any wrist. The rotating bezel on the left side stands out subtly from the case, as does the screw-down crown. The watch’s case back is a screw-down sapphire crystal back, which rounds out the attractive design. The “anti-reflective sapphire crystal” watch glass offers extensive protection against accidental scratches and damage. Beneath it, the dial of your new dream watch is black. Luminous hands and hour markers illuminate the Swiss Military by Chrono SMA34106.05, ensuring excellent readability even in low-light conditions. At the heart of this timepiece is a Swiss-made automatic movement which, as is customary for Swiss Military by Chrono watches, guarantees precise timekeeping and offers the following functions: date, minutes, seconds, and hours. Its water resistance of 20 atm (test pressure) ensures it’s well-suited for everyday use, as shown in the list below: 3 atm: Water splashes while washing your hands are okay. 5 atm: You can shower and bathe with this watch. Swimming or diving is not permitted. 10 atm: The watch can handle a trip to the pool, but not diving. 20 atm and above: At 20 atm and above, the watch is considered water-resistant and suitable for swimming and shallow-water diving*. You’ll enjoy your new Swiss Military by Chrono watch even more thanks to the high-quality calfskin strap—color: black—with a pin buckle. The calfskin strap offers exceptional comfort and can be worn on wrists up to 215 mm in circumference. *Water resistance is not a permanent feature and must be checked regularly and professionally when the watch is used accordingly. For watches with screw-down pushers and/or a screw-down crown, ensure that these are securely screwed down by hand so that the watch can be water-resistant at all.
