“Lever Chronometer with Split-Seconds Chronograph” Breguet, No. 4330. Made circa 1920. Very fine and very rare, silver and gold, keyless lever chronometer for Besançon Observatory Timing Contest, with split-seconds chronograph, 30-minute register and the original Breguet morocco leather-covered box. Accompanied by a certificate. Four-body, massive, "bassine”, polished with yellow gold split-seconds button and setting pin surround. Hinged silver cuvette. Notes The viper's head was the official Besançon Observatory punchmark. The more complicated a timepiece is, the more difficult it is to adjust, particularly with complications such as a chronograph, split-seconds function, and/or a register. The additional wheelwork affects the timepiece's functioning, because of the amount of energy required - but often only sporadically, when, for example, the chronograph is in use - and because of the friction to which the moving parts of the mechanism - levers, springs, etc. - are subjected. Another Breguet split-seconds chronograph with Besancon Observatory mark was sold by Antiquorum, Geneva, November 12, 2006, lot 308.
