I really enjoy cheaper vintage watches that call back to when everyone had one of them on their wrist.
Something about a semi-autonomous machine ticking away on your wrist, whether you're looking at it or not, using no electricity, is just intrinsically satisfying to me.
I got into watch servicing pre-covid, but never got into actual fabrication of parts. I mention pre-covid because it really got popular when everyone was stuck inside and there was a sudden loss of cheap ebay parts watches to pick from.
