Omega Seamaster Cosmic Ref. 166.025

ere is a lovely, all original Omega Seamaster Cosmic from 1970. The charcoal dial is in excellent condition, with a steel Omega logo and block steel hour markers with the original lume dots at the ends. The white outer chapter ring has charcoal stripes per second. Some marks can be seen around the top of the dial. The date can be quick-set by repeatedly pulling the crown out to the outermost position and is displayed in the steel framed window at 3 o’clock. The steel baton hands have the same original lume as the hour markers and are in fine condition with some minor aging.

The monobloc cushion shaped stainless steel case has a sunburst pattern and thick beveled integrated lugs as was common on this model, giving it a very solid look on the wrist and also making it look bigger than it is. It is in fine condition, with some overall wear. The brushed stainless steel case back has a well-preserved hippocampus logo engraving and is overall in fine condition with a few nicks and scratches showing. We have placed a nice grey strap on this watch to make it a whole.

Inside the watch, Omega’s fantastic 565 movement beats strongly and accurately.  The watch was fully serviced and comes with a 12-month warranty on its proper mechanical functioning.

This Seamaster Cosmic looks stunning on the wrist with the dark grey dial and grey leather strap. This is a watch that can be worn as a daily driver while also adding that special flair to special occasions.

The Omega Seamaster was introduced in 1948 and is, as such, the longest continuously running line within Omega’s catalogue. While these early Seamasters might look like dress-watches by today’s standards, their unique selling point was the use of an O-ring gasket between the case and the screw-in caseback. This development, taken from Submarine innovation during WWII, provided the watches with waterproofing that is anything but dressy. A major upgrade over older lead and shellac alternatives.

In 1955, a Seamaster was taken to a record depth of 62,5 meters by diver Gordon McLean, off the coast of Australia. Note that this is still before it took on the archetypal form-factor of a dive watch in 1957, with Ref. CK2913. Since then, models with and without divetime bezels have co-existed within the Omega Seamaster collection.

1950’s And 1960’s non-divetime-bezel Seamasters offer amazing value within today’s vintage market. Despite their modest diameter, they tend to have great wrist presence due to sporty, beefy cases. Countless variations exist, from rare curtain-dial double-signed Seamasters to fancy lugs and cross-hair dials. Great finishing and quality movements ensure these are still awesome everyday watches today. Since they were produced in relatively large numbers, a good example does not break the bank like some technically and historically lesser watches do.

The vintage diving Seamasters, such as the Ref. CK2913, Milspec Seamaster 300 or the famous PloProf, have become highly sought-after and collectible.

It is impossible to write about the Omega Seamaster without mentioning James Bond. When Pierce Brosnan took on the role of British super spy in 1995’s Goldeneye, a tricked-out quartz Seamaster diver was on his wrist. Different Seamasters have featured in all Bond-franchise films since. There was even a sly dig at Omega’s biggest rivals in Casino Royale when a James Bond/Vesper Lynd conversation went: “Rolex?” “Omega.” “Beautiful!”  Oh snap!

The Omega Seamaster collection has everything you could want from a watch. The history, the significance, the quality and the sheer variety. From simpler versions that present massive value, to highly collectible and extremely rare examples. A cool, understated look with an adventurous undertone. We love them!
