On the occasion of the Watches & Wonders exhibition, the 1815 Chronograph takes center stage with an exclusive case-and-dial combination. This special white-gold model features blue numerals and a pulsometer scale. It is available only in the fifteen A. Lange & Söhne boutiques worldwide.
The case, in 18kt white gold, measures 39.5mm x 11mm. It has double sapphire crystals.
Movement is the German manual-wind Lange in-house caliber L951.5 with 34 jewels, 18,000 vph and a power reserve of 60 hours. It is a column-wheel chronograph and has four screwed gold chatons and a lever escapement. Shock-resistant balance wheel with eccentric poising weights; balance spring manufactured in-house, precision beat-adjustment system with lateral set screw and whiplash spring.
It is decorated and assembled by hand; precision-adjusted to five positions; plates and bridges made of untreated German silver; balance cock engraved by hand.
Functions are: hours, minutes and subsidiary seconds with stop seconds; flyback chronograph with precisely jumping minute counter; a pulsometer scale.
The dial is solid silver, argenté with hour and minute hands in rhodiumed gold; seconds, chronometer sweep seconds and minute counter in blued steel. In addition to deep-blue printed dial elements, it features a pulsometer scale at its periphery. It is used for heart-rate measurements. This is done by stopping the time while counting 30 heartbeats. Then, on the pulsometer scale, the chronograph sweep-seconds hand provides a direct reading of the number of beats per minute.
