The S. Epson caliber VS75 is a solar-powered quartz chronograph movement with a 24 hour indicator.
This calibre has been produced since at least October 2012 (VS75A), with an evolution update around August 2023 (VS75B).
VS75A VS VS75B:
The main difference between the A and B versions appears to be the capacitor part number.
VS75A | VS75B | |
Capacitor Part # | 3023.24H | 3023.34T |
Basically, the 3023.24H capacitor (aka secondary battery) was replaced with a newer 3023.34T.
