In 1878, the city built an observatory for a single reason, to allow its watchmakers to set their watches by the stars.\u003c\/p\u003e\n\u003cp\u003eThe Spacegraf revives this founding gesture. On its dial, an entire disc turns to the rhythm of the real sky, this is the sidereal time complication, displaying at every moment the stars actually visible above you. At its center, a second rhythm, far faster: the flying tourbillon of the CMM.32 caliber, manufactured in Morteau, visible both from the front and through a sapphire caseback.\u003c\/p\u003e\n\u003cp\u003eThis is the story the Spacegraf tells on the wrist: that of a region which has always measured time by looking to the sky.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLimited to 150 numbered timepieces.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCELESTIAL DIAL\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe dial is deep black, with a fine sandblasted grain under a black PVD coating, ringed by circular-brushed minute and seconds tracks. At 12 o’clock, the “celestial vault” disc turns once every sidereal day (23h 56min 4s) under a thin sapphire cover that shades from smoky to clear. At 6 o’clock, the flying tourbillon opens the dial onto the movement. The indexes are merged into 3D rings and, along with the numerals, tracks, hands and celestial disc, are treated with Super-LumiNova BGW9 Grade X1. At night, the whole sky glows on the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3D SUPER-LUMINOVA® GRADE X1\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe hour markers and hands are shaped from solid 3D blocks of Grade X1 Super-LumiNova BGW9, so they glow through their full depth.

Its 42mm Grade 5 titanium case is vertically brushed and framed by a circular-brushed bezel, and it holds the complication in just 12.15mm.

Specifically manufactured for the CMM.32 by Générale Ressorts, this large barrel is off-centered in order to make enough room for the gears and the balance wheel so as to preserve a contained thickness.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOPTIMIZED ESCAPEMENT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInterface between the gear train and the regulating organ, the escapement is the place where energy and chronometry intersect in a complex interaction. The escapement is an energy-demanding system, it alone consumes more than half of the barrels’ energy. It is the friction of the anchor pallets on the escape wheel which, despite their lubrication, dissipates a good part of this energy.\u003c\/p\u003e\n\u003cp\u003eThe CMM.32 tourbillon escapement presents notable improvements which reduce this friction thanks to an innovating and particularly sophisticated manufacturing process (LiGA technology). This advanced escapement ensures optimization of the entire mechanics, precision and longevity of the caliber components.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eANTI-MAGNETIC \u0026amp; SHOCK-RESISTANT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDesigned for everyday life, the CMM.32 presents robust technical characteristics for a tourbillon caliber. Equipped with non-magnetic components, such as a Swiss-made non-metallic alloy hairspring, a Glucydur balance wheel with an adjustment mass made in gold and micro-components manufactured with LiGA technology materials, the CMM.32 is capable of withstanding exposures to electromagnetic fields up to 2,000 Gauss, a real feat for a tourbillon caliber.\u003c\/p\u003e\n\u003cp\u003eThe architecture of the tourbillon cage bridge with its free-sprung balance wheel and the shock absorbers manufactured by Kif make the CMM.32 impervious to shocks, vibrations, and acceleration up to 5,000 Gs in all directions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSIDEREAL TIME COMPLICATION\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn 1878, at the request of Besançon’s watchmakers, a presidential decree established an astronomical, meteorological and chronometric observatory in the city. Its purpose was to certify the precision of their watches by observing the stars. The Spacegraf’s “celestial vault” disc brings the principle of the Observatory’s meridian circle to the wrist. The disc turns continuously, set to the same 23h 56min 4s the Earth takes to turn once on its axis relative to the stars. At every moment, it shows the part of the sky actually visible above you.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLEATHER STRAP WITH TITANIUM PIN BUCKLE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis black leather strap with matching black stitching tapers from 21mm to 16mm.
