Thank you for posting this to the web. I was trying to change the battery myself and I could not figure out how to properly get the battery dislodged from the movement. These photos helps immensely. Great site!

I have watches with this machine. I don’t know their exact name but they were distributed like car accessory with BMW. They are designed by BMW and made by Ventura in Switzerland. I found the same watches on ebay but mine has cca 100 higher serial number but also with BMW logo instead of 12.

Yes, but you should know what you’re doing first. There is a link above that I used before. “Full assembling/Disassembling instructions from ETA” click that.
