Peseux 320

Description

One of the most successful (and some even say, it is one of the most beautiful) flat handwindig movements is the Peseux caliber 320. With a height of only 3mm with or without shock protection it is really unique, concerning the height.
This work can handle all gears and trains in one layer, since it only has got a possible decentral, direct driven, second hand.

Since this movement was built over a longer period of time, it was available in different versions, which can be distinguished on the balance (screw balance, simple three-leg ring balance), shock protection (without or with Incabloc), with our without moveable hairspring stud and with or without decentral second hand train on "6"

On the dial side, the Peseux 320 looks very cheerful. Lots of free space and a yoke winding system.

The movement in the modern version in copper color with shock protection was donated by Harald Hoeber. Thank you very much!
