Since 1993, the Seamaster Professional Diver 300M has been an iconic timepiece, and the contemporary collection continues to pay homage to its legendary ocean heritage while incorporating OMEGA's latest innovations and designs. This 42 mm model, crafted from stainless steel, features a striking green ceramic bezel adorned with a white enamel diving scale. The polished green ceramic dial showcases laser-engraved waves and houses a practical date window at 6 o'clock.

The rhodium-plated skeleton hands and raised indexes, filled with white Super-LumiNova, ensure optimal visibility in various lighting conditions. Adding to its functionality, the watch includes a conically designed helium escape valve. Presented on an adjustable stainless steel bracelet with an extra diver extension, this timepiece is driven by the OMEGA Master Chronometer Calibre 8800. The movement's precision and reliability can be admired through the sapphire-crystal caseback, which features a distinctive wave-edged design. With water resistance up to 30 bar (300 meters / 1000 feet), this Seamaster model is not only a symbol of style but also a reliable companion for underwater adventures.

With dimensions including a 20 mm distance between lugs, 49.9 mm lug-to-lug, 13.6 mm thickness, and a 42 mm case diameter, this Seamaster seamlessly blends robust construction with elegant aesthetics. The total product weight is approximately 198 grams, underscoring its substantial yet comfortable presence on the wrist.
