Picked this up this last week from a new found Friend in my local area. Vintage Hamilton Diver Chronograph in pretty good shape. I'm going to have it serviced in the near future, but despite lack of servicing this watch is keeping excellent time. The gentleman I bought it from dates it to the late 60s or 70s, and everything appears to be authentic (Aside from the band). I'm new to the hobby/addiction, so I don't have the tools yet to open this up, so I'll post more pics later, once received or serviced.
In the mean time, here it is on today:
