PUW 360
Description
1963, the german Pforzheimer Uhrenrohwerke launched their series 360/1360. This differed from the previous series 260/1260 in the balance system and in the main plate, which is now more service friendly divided into two parts.
As balance, the PUW used a very modern ring balance with three legs. The balance stud was now moveable.
In the movement shown here, a KIF Ultraflex shock protection system was used; the gears all run in jewels, 17 in sum. Two of them are cap jewels for the anchor wheel. Other versions were available with Incabloc shock protection and 21 jewels (all gears with cap jewels).
The movement excels through its clear and economic construction and shows clearly, how advanced and competetive watches from germany once were. They only lacked the “Swiss Made” aura…
