I received this circa 1959 Omega from my wife for a 40th birthday present. I have not been able to find any information on it online. It is in a two piece case, with a c.302 movement. The case is stamped 14k gold. I assume the diamond markers were added sometime in the last 50 years. It keeps decent time for a 50 year old watch, ~30 slow per day.
What model is this?
Could this model be white gold?
Are the diamond markers aftermarket?
The power reserve is about 25-27 hours, and it winds smoothly, but stiffly. Is this normal for a small movement this old?
Does the movement look ok from this photo (borrowed from the seller)? Anything I should be concerned about with the caliber 302?
Thanks in advance for any help. This is my first, but hopefully not my last vintage watch.
