Only the cheapest watches are 'unadjusted' from the factory. See, if the watch is 'untouched', then it is worth to mark the position of the roller and to be very careful not to change in any way the hairspring shape and position. After replacing the balance staff just check the performance and probably there will be not big position errors. But having in mind that even unadjusted watches also perform well when the amplitude is proper, check positions with small and big amplitudes. I work mainly on watches that other people have tried to repair and have failed, this is something like faith... I see alot BAD repairs. There are 'ingenious' ways of 'end shake adjustment' and balance staff repairs I meet I even don't want to speak about (here the term 'previous idiots' is right on it's place). Especially with compensating balances, static poising speeds up alot the adjustment, more - it really helps for the balance truing in round. Of course, everything depends on the aim one wants to achieve. -
Are we talking the same ballgame? restaffed balance wheel ? bend, unbend bridge ? -
Yes that is a nice tailstock. I could not see from the photo it would accept a collet. That is probably worth a few hundred dollars but overall the price is high. -
Funny thing is, I did one before this: a Hamilton 974. My grandfather’s watch. That one needed a new crystal & seconds hand (both missing), a fourth wheel (original had a broken arbor), and a new escape wheel (damaged pivot). The broken and missing parts were pretty easy to fix. The escape wheel pivot issue initially escaped my notice. I was so happy to get it working! Lots of sentimental value. -
What I like about the tail stock is that you can put the collets in it to drill holes. I have a peersless lathe but I can’t drill holes because I don’t have anything that can hold collets or a Jacob chuck. That’s why I am interested in buy this one, but yes I feel like it is a little high.
