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.
