Tag WK11100 (200m Aquaracer) battery replacement?

[Fromaffar]

One of the watches mentioned in the title has found it's way to me - it needs a new battery. I used to frequent this forum daily so knew it would be a good place to start on finding the right place to get it done..


I attempted to contact PH user 'Variomatic' by email and by phone - no reply, I guess he's no longer doing watches.

Can anyone recommend where to have the battery changed please - I'd like a pressure test too, as the watch is new to me and although I have the box etc, the history is unknown.

I want the price to be reasonable - and the workshop to be reputable! Cheers.
