====== SZ03 ======
**Calibre SZ03** 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 the 2003 as the [[SZ01]]. This was followed in [[2014]] by this Cal. SZ03. In addition to a 60 minute (rather than 30 minute) chronograph counter at 12 00, as in [[SZ02|Cal. SZ02]], Cal. SZ03 features an unusual calendar arrangement Windows at 12 00 show the day of week and month, a central pointer shows the date, and the subdial at 6 00 shows the [[week number]].

===== Applications =====
  * [[Sinn 6052|Sinn 6052 Frankfurt Financial District Watch with calendar week display]]
