It is a 105 21 jewels model that was made in Swiss. It doesn’t work but with good balance staff. The dial is aged and fading. It would be a nice HASTE watch for your repair project. I try my best to describe the item.
Partial Vintage Haste / Berna / Valjoux Caliber 22 Chronograph Wristwatch, Parts
Unsure about setting/winding – missing stem. The balance staff is intact, the balance swings freely, and it ticks with gentle pressure applied to the gear train. This item is being sold “as is”. A PROPOS DE NOUS.
