I don't have the measuring tools to measure the watch, and I do not know the production year of this watch. It was purchased pre-owned from a shop dealer in Hong Kong.

I have not serviced this watch other than to check it was in good working condition at the time of purchase.

I haven’t measured the link but my wrist is the usual 16.5cm smaller wrist. I have an additional link, and these omega links should be common if you need to buy additional links.
