Ok. He gave up and sent me the watch. Mystery solved. I never would have guessed. Peseux 170. He needs a staff. I have a 190. The book says the balance is the same. Do I sacrifice my parts watch for my friend? Do I swap it out for him? <sigh>
Same staff for both calibers. And isn't that what spare movements are for? You could also get him to buy you a beer and you could pick one up here. https://www.ebay.com.au/itm/PESEUX-...30:m:mQTAHe5i_SuiLWKbk5Rmkjg&var=574344210571Purchases made through these links may earn this site a commission from the eBay Partner Network
^^ yup- not worth scrapping an entire spare movement if you only need a £7 Part https://www.ebay.com/itm/113011191008Purchases made through these links may earn this site a commission from the eBay Partner Network
Sadly, I'm not a watchmaker. Balance staff complete only I've never replaced just the staff successfully. Not my watch and god knows, he's not paying me.
