The heat after summer makes diving watches a must-have on the wrist. This Omega Seamaster Diver 300M in a 42mm stainless steel case and bracelet: an iconic watch since its launch in 1993. Now it’s even better. The bezel is in black ceramic with a white enamel diving scale. The dial is also polished black ceramic with a laser-engraved wave pattern and a date window at 6 o’clock. The skeletonized hands and embossed hour markers are rhodium-plated and filled with white Super-LumiNova, while the helium escape valve is conical. The super-magnetic OMEGA Master Chronometer Calibre 8800 is visible through the wave-edge sapphire crystal caseback.
