The new Seamaster 300 opts for polished black ceramic on the bezel, and features a sapphire crystal case back through which the all new Co-Axial Calibre 8400 can be seen. As always, it’s a pleasure to be able to see a movement at work, though it could have been interesting to see a solid case back with the vintage hippocampus engraving. Nevertheless, the self-winding movement boasts COSC-certification, a 60-hour power reserve, 15,000 Gauss of magnetic resistance, and a co-axial escapement. Naturally, the watch is water resistant to 300m.

The black model in all stainless steel is the most faithful to the vintage Seamaster 300, though two-tone and gold options exist as well, as do models with blue bezels and dials standing in for the black ones you see here. We’ll be bringing you live photos of all the various combinations over the coming days.

The Omega Seamaster 300 starts at CHF 5,500 for the stainless steel model above. For more, visit Omega online.
