====== SZ05 ======
**Calibre SZ05** is an [[automatic chronograph]] movement from [[Sinn]] based on the [[Valjoux 7750]].

Sinn has long used the Valjoux 7750 movement for their chronograph watches, but began reworking the movement in the 2010s. Noting that the traditional 30-minute counter of the 7750 is difficult to read, Sinn modified the movement to feature a full 60-minute counter at 3 00 instead. The date window was moved to 6 00 and the day wheel and hour counter removed.

===== Applications =====
  * [[Sinn 358|Sinn 358 Anniversary]]
  * [[Sinn 936]]
