Lorus ladies/girls digital watch (needs a new battery) (Peachcroft OX14)

Lorus (labelled as CAL 2017 R23) digital watch with a white strap and metallic/white face and purple function buttons and detailing. Supplied in its original case with an instruction book but the watch doesn't turn on so it will need to have a new battery fitted. Was working fine when packed away in a drawer but that was some years ago. Probably has a load of functions such as stopwatch, alarms etc and labelled as water resistant.
