Help please with my newly acquired 60s Hamilton

Spruce

I’ve just bought this on eBay ($162.50 plus tax and postage, since the info is readily accessible) but I’ve never owned a Hamilton before.

It’s my sort of dial and, the seller assured me, it’s all original save for a new crystal and it’s recently serviced (I know 😎 ) and runs well but I’ve no real idea what I’ve bought apart from the facts that I like the look of it and I wanted to add a Hamilton to the collection. The seller advised that he forgot to ask for movement photos when he had it serviced.

I’ve assumed it’s a monocoque case but apart from that, if anyone has any information about it I’d be grateful.

I'm aware, from reading up, that in the 60s, Hamilton bought in Buren movements and I’m also wondering if this might be a microrotor movement.

I don’t consider myself an authority on Swiss made Hamiltons, but I have long been under the impression that only the early Hamilton automatics (while Hamilton was still in business) used the microrotor Buren movements. And I think these were all marked with Thin-O-Matic on the dial such as the sample.

After the buy out by the Swatch group, as far as I know, Hamiltons which were automatics, used Eta movements. Except for a few that used Kurth Freres movements. If the seller can’t tell you, I guess it is unlikely we’ll be able to tell you, either. Show us a picture with the case back off. Or whatever you have to do.

Given the time period in which your watch was likely produced, I would venture its movement might be a Hamilton cal. 64A -- i.e., ETA cal. 2452. Looking forward to photos. Cheers!

Having taken your first step down the Hamilton rabbit hole, you might find the linked site of interest Vintage Hamilton Watch Restoration (hamiltonchronicles.com)

All this talk of Hamiltons this morning has influenced my decision about which watch to wear today.

Great catch, @Spruce - certainly does look like your kind of watch! I’d be interested to know what movement is inside once you get it checked over.

Will do. Already looking for a chisel to open the caseback when it arrives 😉
