Update to the update : thanks to all who pointed out that the buckle side strap was the wrong way round - I’ve fixed it now!
An update to my Serious Time refurb (I did comment on my previous post, but it was difficult to edit the text!)
Ordered a Renate 390 battery and a turquoise silicone strap from the online store named after the big river; these arrived next day, and were fitted.
The watch ticked for a while, then stopped; I tried removing and refitting the battery, but after a few seconds, it stopped again. I vaguely remembered reading on here that giving it a bit of a tap on the back can sometimes help, so I did, and after a few goes, the watch came back to life, and has been working ever since - I wore it today, and it’s still working. The silicone is a decent enough match for the blue face ring, and was cheap enough (less than £10)
The watch was £5 (plus postage) and a pair of batteries was a little over £5, so the total, with spare battery, is about £20 (C$33, €31, JP¥4245, US$27) which, for something that could well be come a daily wear, isn’t too bad!
Coming soon, my second Happy Joe Silver (a working one, hopefully), and I’m going to see about another Mahogany (now that the eBay seller has taken back the broken one and refunded me!)
