This watch is 20 years old this year! Finally changed the battery just to see her working again - what a flashback!
She needs a good cleaning and I don't have silicone oil yet, so she'll come back apart for a servicing as soon as I do. No gaskets available, so I'll reuse the old one (still in one piece) but won't test the WR capabilities I don't think.
What a great module, too. Aaah, happy reminiscing .
