I was tempted this morning to wear the "Winner" skeleton to see what reaction, if any it would generate, but I decided instead to continue working my way through the waifs and strays that have been awaiting my attention since I got back from holiday.
This rather charming little late fifties Linaso Ancre 17 Rubis "Candido" - Swiss (ETA 1132 I think), was crying out for attention, so I opened it up and took a look. It was running +2000 s/day or something ridiculous, and I had assumed it would be all gummed up.
However when I popped the lid, it was pretty obvious what the trouble was. The hairspring had been molested. It looked like someone had attacked it with blunt chopsticks. A little massaging and it un-sproinged, and a few more caresses of the tweezers removed the remaining rather major kink.
I also removed some fragments of the original waterproof seal, which I initially thought might be shattered bits of case, as they were a metalic grey and brittle. Perhaps one of them had managed to get in to the works at some time in the watches history, and caused the "springulation" problem.
It is still a little wild in terms of the beat error, but it now sits at a much more respectable -5 to +15 s/day. I was tempted to fiddle some more to get the beat error down, but I'll wear it for a bit longer and see what it looks like once the cleaning and oiling have had their full effect.
It also needs a new strap. The original is in almost perfect condition, but it has become as brittle as the seal that I removed. I'll try a little leather rejuvenation cream on it, but I think the leather is probably beyond saving. The crystal will need a little polishing too, but other than a few surface marks, it is in pretty good nick.
