Sinn Spezialuhren EZM 1.1

The Sinn EZM 1.1, reference 506.010, is a steel chronograph in a limited edition of 500 pieces. Its bead-blasted case is 43 mm across and 16.4 mm thick, water resistant to 200 metres. TEGIMENT hardening increases the case surface's scratch resistance. The screw-down crown sits on the left of the case beside the push-pieces. Self-winding calibre SZ01 is shock resistant. The black dial displays a date under a sapphire crystal, within a captive rotating pilot's bezel with minute ratcheting. Ar-Dehumidifying Technology prevents fogging and improves functional reliability.
