Hi all - it's a long shot but I figured it's worth asking here at least... I've inherited my dad's gold Rotary dress watch. From what I can see, the hallmark on the watch back indicates it was 1964-65. I don't expect it's hugely valuable (not that it's going to be sold anyway) but I'm interested to find out some more about it. It's simply marked 21 jewels and is in a marked Dennison case. There's no obvious model number or serial number on the movement and I've ploughed through hundreds of photos online but not found another watch quite the same as this ... The case back shows a couple of ID numbers; I'm presuming one is a serial number and one is the ID number of the case itself? Finally, the watch had a gold bracelet on it which I think might have been a later addition as its hallmark suggests it came from the mid 1970s. I've taken that off and put it on my gold capped Seamaster De Ville, which I think suits it quite nicely ... thanks in advance for any ideas or pointers - I guess there's not quite such a devoted Rotary watch owners community out there as OF
