    I have a f300 Constellation bought from a forum member a while back that now requires a new battery.

    I have a Renata 344 (which I believe is the correct battery) but I can't find instructions on how to open the watch and fit it.

    Can anyone give me any guidance please?

    Thanks in advance!

    Not meaning to sound like a dick (surprising, I know) but, if you don't know how to do it, I would take it to a watchmaker to avoid damage.

    Not at all - if there's even a remote chance of damage to the watch I think that's good advice!

    Same advice from me. I have seen a lot of f300 with damaged index fingers and wheels due to screw drivers sliding off the screw head.
