Up for sale is an Omega Seamaster 300 Reference 166.024 with Cal. 563. This is a nice example that returned from a full factory service by Omega in Switzerland about two years ago. Since its service, the watch has only been tried on but not actively worn.

The case is in nice condition, having been refinished to factory specifications during the Omega service. The caseback engraving is light and barely visible from years of wear, which is common for these models as the hippocampus logo was originally etched and tended to fade over time. I have a service caseback that I can sell for an added cost. The only other "issue" that i've noticed is that the factory service bezel can sometimes be difficult to turn in certain spots, though it remains fully functional and otherwise easy to use. The spring may require some adjustment.

The movement runs great and to factory specifications post service. During the service, Omega installed a new dial, hands, crystal, crown, and gaskets. The bezel was with the watch before.

This is similar to a "watchco", but has an original case and what I believe to be an original SM300 movement serial.

The watch comes installed on a preowned Uncle Seiko Holzer strap, which pairs nicely with the watch and offers a comfortable fit. I had this extra Omega clasp cover in my parts drawer that I installed on the bracelet.

A nice opportunity to own a factory-restored Omega Seamaster 300, offering the best of both vintage authenticity and modern reliability.
