This 39.5 mm Planet Ocean 600M has a case and bracelet in stainless steel.
 

The vertical brushed ceramic dial in OMEGA’s own Summer Blue is PVD treated and varnished with a gradient finish to reflect the watch’s level of water resistance. A blue ceramic bezel with light blue diving scale encircles the bold display, which includes blued hands and indexes filled with a unique light blue Super-LumiNova.

Turning the watch over reveals a stamped commemorative Seamaster logo depicting a trident-bearing Poseidon and two seahorses: OMEGA’s 1956 original and the brand’s current design. Behind which sits the OMEGA Co-Axial Master Chronometer calibre 8900.

As the name makes clear, OMEGA’s Seamaster Planet Ocean 600M is water resistant to 600 metres and includes the essential helium-escape valve.
