Since its introduction in 1993, the OMEGA Seamaster Professional Diver 300M has captivated watch enthusiasts with its legendary design and exceptional performance. The latest collection honours that iconic ocean heritage while integrating OMEGA’s most advanced innovations and refined aesthetics.
This 42 mm model is crafted in stainless steel and features a striking blue ceramic bezel with a white enamel diving scale. The polished blue ceramic dial, adorned with laser-engraved waves, is complemented by a date window at 6 o’clock, blending elegance with functionality. Skeletonised hands and raised indexes, rhodium-plated and filled with white Super-LumiNova, ensure optimal legibility under all conditions.
A reimagined conical helium-escape valve adds both practicality and a distinctive design touch. Secured by a polished stainless steel bracelet, the watch is powered by the OMEGA Master Chronometer Calibre 8800, visible through the sapphire-crystal, wave-edged caseback. METAS-certified, this movement sets the benchmark for precision, performance, and magnetic resistance.
The Seamaster Diver 300M combines technical mastery, sophisticated design, and enduring maritime heritage, making it the ultimate statement of elegance and adventure.
