Omega Seamaster 300 39mm steel on steel

A 60th Anniversary tribute to one of three classic timepieces released in 1957, this Seamaster 300, limited to 557 pieces.
It is based on the CK2913 and retains the Naiad sign on the crown, which back in ’57 was a mark of the watch’s exceptional water resistance, as well as the 1957 Seahorse on the caseback.
In common with all three watches in the box set, it is cased in brushed and polished stainless steel and features the word TRILOGY and the limited edition number on the black ‘tropical’ dial.
The stainless steel bracelet has been updated for strength and features a retro-style OMEGA logo on the clasp. It is powered by the Master Chronometer 8806.
