View source for SZ02

'''Calibre SZ02''' is an [[automatic chronograph]] movement from [[Sinn]] based on the [[Valjoux 7750]].

==Overview==

Sinn has long used the Valjoux 7750 movement for their chronograph watches, but began reworking the movement in [[2003]] as the [[SZ01]]. This was followed in [[2006]] with this Cal. SZ02. The main difference being a 60 minute (rather than 30 minute) chronograph counter.

Once again, for the SZ02, Sinn reworked the chronograph counters. This movement was designed to be rotated 180 degrees, with the crown and [[pusher]]s on the left. In this orientation, chronograph minutes are displayed in a subdial at 6:00 with chronograph hours at 12:00. The minutes counter is a full 60, however, unlike the Valjoux. [[Small seconds]] are displayed at 3:00.

==Applications==

* [[Sinn 303|Sinn 303 Football Chronograph]]
* [[Sinn U1000]]
* [[Sinn EZM 13]]
