Looks like a match to this offsite 1972 ad: reference 370106. Not sure if watch in ad is 23 jewels, and is shows a strap and not the link band you currently have, maybe the link-band option is a different reference number.
It also looks like the bezel would come off to allow access to the movement from the top. If so, it would likely have a two-piece stem.
