Can anybody please tell me what battery I should use for this watch. There is a Renata 371 installed at the moment which was put there to check whether the watch is working. Thankfully it is but I would like to install the correct battery.
It's hard to read the numbers on the movement, but this looks like an Omega 1436 / ETA 255.441. If that's right, the correct batter should be a Renata 373 or Maxell SR916SW.
