Casio 4723 model watches (Wave Ceptor WVQ-550) require a CR1616 Lithium 3V coin cell.
As that information seemed to be entirely absent from the internet I have secreted it here for all eternity.
Get one off ebay and install it yourself or pay £10 for the nice person at H Samuel to do it for you. Either way the waterproofing rating will no longer be reliable.
Good watch though, eats a battery in 3 years though. Meh.
