Built around a 41.5mm round stainless steel case measuring 16.8mm thick, this Seamaster 300m is equipped with a uni-directional rotating bezel, a screw-in crown, a solid case back, and scratch-resistant sapphire crystal — all working together to deliver water resistance rated to 300 metres / 1,000 feet.
The blue dial is driven by an automatic chronometer movement featuring Omega's Co-Axial escapement, a complication set that includes a chronograph function, and COSC certification confirming its precision credentials. The stainless steel bracelet carries a brushed and polished finish and closes with a push-button folding clasp.
Reference 212.30.42.50.03.001 is presented in new/unworn condition, making it a compelling choice for those seeking a capable diver's chronograph from one of watchmaking's most storied names.
