Omega CK2907 Seamaster Cal.321 Chronograph from 1958

Extraordinary and early example of the Omega Seamaster Chronograph.
This is the first reference from the Omega Seamaster chronograph production line featuring some very attractive and collectable aspects.



The dial has acquainted a subtle warm yellow patina glow across.
Lume filled alpha hands and alpha hands sunken chronograph sub dials, the old font Seamaster signature, applied Omega logo and Tachymetre outer scale all add up to the best configuration in the production line of Omega Seamaster chronographs.
All lume plots have a stunning orange patinated colour and are intact.

The beefy lugs stainless steel case shows to be unpolished. Some normal wear throughout, no deep dents but some normal superficial scratches.
Original small pushers and 32 teeth Omega signed crown.

The early Cal.321 movement with 16 million serial number dates this watch back to 1958, just one year after its first release in the Omega Speedmaster ref. 2915 by Omega in 1957.
Incredibly clean movement showing no signs of aging, pitting or dirt of any kind. Running great and keeping accurate timing.

Rare watch that does not surface the market often, let alone in a condition like this.

Aftermarket strap, Original vintage Omega buckle.
