ETA caliber 6497 is a mechanical manual wind movement with 17 jewels. It is Swiss Made.

Non-Hacking

The 6497 is a non hacking caliber, but there are brands (such as Chronoswiss) that have heavily modified base 6497 movements and added hacking mechanisms. If you know of a specific 6497 based caliber with an additional hacking module added, please mention it below.

Pocket Watch Roots

The 6497 is often referred to as a pocket watch movement because that is the roots of its design.

Agree. It’s beautiful and so clear to see all the moving parts. I can’t wait to get a watch with a caliber 6497 movement inside.
