SZ04

Calibre SZ04 is a regulator movement from Sinn based on the Unitas 6498.

Overview

Although Sinn had been reworking the Valjoux 7750 since 2003, their fourth movement, Cal. SZ04, marked the first time the company had worked on the Unitas 6498 base. Their modification was quite simple, moving the hour hand to a subdial at 12:00. Combined with the existing small seconds at 6:00, this created a regulator layout.
