The Seamaster Diver 300 M reference 210.30.42.20.03.001 features a 42 mm stainless steel case with a blue ceramic bezel insert and white enamel diving scale, offering both high scratch resistance and clear legibility. A helium escape valve at 10 o’clock underscores its professional dive credentials, while the screw-down crown and robust construction support 300 m of water resistance.


Its blue ceramic dial showcases Omega’s signature laser-engraved wave pattern, applied indices filled with Super-LumiNova, and a date window at 6 o’clock for balanced symmetry. The watch is powered by the Omega Co-Axial Master Chronometer calibre 8800, an automatic movement certified by METAS for precision and anti-magnetic performance, with a 55-hour power reserve and bidirectional winding. The stainless steel bracelet combines brushed and polished surfaces and is fitted with a secure clasp, giving the watch a sporty yet refined presence on the wrist.

Personal Brand & Photography Story

As a dedicated hockey coach and passionate timepiece collector (@pucks_timepieces), I've spent years immersed in the world of horology. I now combine this passion with my hockey-playing daughters, and together we create the unique presentations you see here. Our photography is inspired by contemporary artists like KAWS, Banksy, Joan Cornellà, Death NYC, and Shepard Fairey. This artistic approach adds a distinctive, creative character to how each watch is presented.
