An old SM 300

Thought I'd take my SM300 it out for a spin and a photo shoot. I have not worn it in years...

Omega Seamaster 300
Case 166024-67
Cal 563 SN 28272131 From 68/69
Dial is the older "12" version which was switched in 67 to the big triangle.
Older style Naiad crown before switching to screw down in 67.

I picked this up locally in Seattle from the estate of the original owner about a decade ago. It was sporting a 70s era stretch bracelet. I had the movement serviced, put on a leather strap and the crown replaced. The case was left unpolished as I liked the honest wabi on it.

Some interesting observations:

• The case, dial and movements dates to about 2 years of each other, consistent with Omegas of that era.
• Caliber 563 was used for US bound SM 300s and a little less common than the 565.
• The hands look more fresh than the dial, although they have taken on a nice even patina consistent to 70s era dive watches.
• The crystal has an internal cyclops lens, with the Omega logo etched in the middle. I do not often see SM300 crystals with cyclops.

With a 1680 from the same era.
