Sold on 25 ventôse an 11 (16 March 1803) to Mr Mariani for the amount of 960 francs.
With the term nouveau calibre (new calibre), Breguet described a new type of movement that he introduced for simple watches after 1796, following his return from exile, and designated as the final development for his watches made without striking or repeating. Usually this type of watch was constructed in a smaller size and was rarely seen with a subsidiary dial for the seconds.
The pare-chute (parachute) suspension is a safety device invented by Breguet to protect the pivots of a balance from damage if the watch is dropped or knocked. The bearing is fitted into a spring which flexes with the inertia of the balance and allows the shock to be taken by the stronger pivot shoulders of the balance staff. Sometimes it was called suspension élastique. This invention is fully explained and illustrated by George Daniels in his The Art of Breguet (1975), pp. 331-332, ill. 407a-b, 408 and 409a-b.
