Omega Seamaster 300 (Ref. 165.024) WatchCo

There is something about the early vintage Omega Seamasters that truly embodies the golden era of dive watches of the 1960-1970's. Omega has a long history and heritage in dive watches, which dates back to the 1930s.  The seahorse adorned case back of the Seamaster series pays tribute to Neptune, the Roman god of the sea. The seahorse logo was conceived by engraver Jean-Pierre Borle.  He was inspired by an image of Neptune driving a chariot pulled by seahorses, which is why the Omega seahorses are depicted wearing bridles.

So what's a WatchCo Omega Seamaster 300?? Well, imagine you found a surplus of Omega service parts, and you could essentially build a watch from those parts...  That's exactly what a WatchCo Omega Seamaster 300 is! WatchCo was an Omega authorized service center in Australia. They aren't anymore but still have a supply of parts for omega watches including cases, bezels, dials, and hands. WatchCo is known for assembling 1960s style Seamaster 300s from a stock of genuine Omega service parts. The watches are assembled using a vintage movement that is sourced to power the watch. The WatchCo reference 165.024 has a specific feeling and look that centers it as one of the most desirable vintage Omega diving watches ever produced by the brand. The bi-directional ratcheting bezel, luminous bezel insert, the high visibility dial, and overall larger size for a watch of its time period allowing it to remain relevant to today's sizing trends while quite literally being new old stock. The WatchCo Seamaster 300's will pass pressure tests and can actually be used for diving if you wish. The price point compared to the vintage examples is also quite affordable for a watch that you can use as a daily driver suitable for pretty much anything you can throw at it... Not literally but figuratively speaking of course!
