100.8 description
Calibre 100.8 features a Grossmann balance; hand setting override and start of movement with lateral pusher; second time zone (24-hour display) by means of exterior revolving hand, time zone display that can be corrected backwards and forwards at any time using the separate crown at 10 o’clock; space-saving modified Glashütte stopwork with backlash; adjustment with Grossmann micrometer screw on cantilevered balance cock; pillar movement with 2/3 plate and pillars made of untreated German silver; balance cock and escape-wheel cock hand-engraved; broad horizontal Glashütte ribbing; 3-band snailing on the ratchet wheel; raised gold chatons with pan-head screws; separately removable clutch winding mechanism; stop seconds for hand setting. It consists of 253 parts including 26 jewels.
Calibre 100.8 features the characteristic components of the Moritz Grossmann movements, such as the 2/3 plate with the raised gold chatons, the Grossmann ratchet, the separately removable winding unit with pusher mechanism and the cantilevered balance cock with micrometer screw, as well as the mass-optimized balance.
On the GMT, the mechanism for the second time is integrated into the movement on the dial side. The 24-hour display is transmitted via the hour wheel of the centre time to another hour wheel and an intermediate wheel to the ring of the second time zone.
The second time zone display can be adjusted via the second crown at 10 o’clock. A ratchet wheel with ratchet spring is used to adjust the time in the pre-defined hourly gearshifts.
