450 CHF

1 in stock

The Calibre 17 is based on the ETA 2894-2 modular chronograph movement.

In the first series of production, the Calibre 17 was called Calibre 7, the correction came later in order to avoid the confusion with the ETA 2892/2893 based movement which remained Calibre 7 until now. This movement is a very rare prototype from the first series, bearing the name Calibre 7, which is in fact based on a 2894 chronograph but with a slightly difference at the oscillating weight design.
