Patek Philippe

BRAINS!!!

That blurry thing in the middle is not my poor technique this time, that's a vibrating lever of some sort, used to convert the quartz oscillations into the oddly-smooth sweep of the second hand

sadly I never got a wrist shot, but this is not a small piece, i'd estimate 42mm or so, and perhaps 15mm thick

thank you so much for sharing this

unfortunate part of Horological History

but then again that was probably happiest days for Stern family

selling such "super complicated caliber" for such

nice price tags I guess that cost more than 200 $ :0)

 ... cost benefit must be outstanding for this one

Sure keeper for next generation LOL

This one didn't qualify for a Geneva Seal, right? 

Ah, the 70s, the decade that brought the world digital watches, Nautiluses, and Aquanauts.

Will the Stern family consider producing a hybrid design similar to the Seiko SpringDrive?

After seeing a quartz in the back of a Patek watch.

It make watching a mecanical movement at work all the more beautiful to watch.
