    Hi guys,
    I opened my Tag Heuer F1 Chrono (CA1211-RO) to change the battery and I saw a loose screw (or broken screw).
    Two questions:
    1- The battery type inside is a Varta 394. In my web search, I think the right battery is a 395. Anybody knows who's the right battery type for this watch?

    2- In my image, you knows if the hole to the loose/broken screw are well sign? If are broken, are any problem to leave the broken screw in place (I think it's a hard work to change it).

    If it's working and nothing is rattling around, I'd just leave it and replace the battery.

    Thanks. Only when I put the battery a can will see if all it's OK.
