Rotary GB05521/04 The Rotary men's watch GB05521/04 is a modern timepiece from the Contemporary 40mm 5ATM series. It's the perfect choice if you're looking for a watch with a contemporary look. The watch features a gold-colored case made of stainless steel, which stands out as a real eye-catcher thanks to its polished and brushed finish. The round case is 40 mm wide and 8 mm high and, depending on individual taste, of course, complements nearly any wrist. The fixed bezel stands out subtly from the case. The watch’s case back is a pressed stainless steel back that rounds out the attractive design. The “anti-reflective sapphire crystal” provides 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 Rotary GB05521/04, ensuring excellent readability even in low-light conditions. At the heart of this timepiece is a quartz movement (battery-powered) which, as is standard for rotary watches, guarantees precise timekeeping and offers the following functions: date, minutes, seconds, and hours. Its water resistance of 5 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 fine. 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 Rotary watch even more thanks to the high-quality stainless steel link bracelet—available in silver or gold—with a butterfly clasp. The stainless steel bracelet offers exceptional comfort and can be worn on wrists up to 210 mm in circumference. *Water resistance is not a permanent feature and must be checked regularly and professionally when the watch is used as intended. For watches with screw-down pushers and/or a screw-down crown, ensure that these are securely tightened by hand so that the watch can be water-resistant at all.
