Inspired by a 1970 Original

The Mighty Omega Ploprof dives again, this time crafted in O-MEGASTEEL with a sun-brushed dial in Omega's own Summer Blue with a gradient finish to reflect the watch’s level of water resistance. The bezel is produced in transparent sapphire crystal, varnished blue on the back, to reveal the light blue diving scale beneath.

The iconic mono-bloc case includes the famous screwed-in crown and the characteristic security pusher at 2 o’clock, which on this edition sports a ring in blue ceramic. In keeping with the color code, Omega has filled the varnished hands and indexes with a unique light blue Super-LumiNova.

Turning the watch over reveals a laser-engraved commemorative Seamaster logo, framed by engraved waves and 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 8912. An original ladder-style blue rubber strap completes the look
