Richard Lange Jump­ing Sec­onds In Pink Gold

ZbBZ (Singapore) - - INTELLIGENCE -

The Richard Lange Jump­ing Sec­onds made its de­but last year in a plat­inum case, which proved to be an in­stant hit. This year, Ger­man lux­ury watch­maker A. Lange & Sohne has fol­lowed up with a ver­sion in pink gold with match­ing ac­cents on the dial and buckle, also lim­ited to 100 pieces.

The clean, min­i­mal­ist time­piece boasts an ex­cep­tion­ally com­plex move­ment, which pays trib­ute to watches for sci­en­tific ob­ser­va­tion. It is driven by a one-sec­ond con­stant-force es­cape­ment with an in­te­grated jump­ing mech­a­nism, which en­sures ac­cu­racy and pre­ci­sion.

The largest sub-dial show­cases the blued steel sec­onds hand. A “zero-re­set” mech­a­nism with a multi-disc clutch pro­pels the sec­onds hand to jump to the zero po­si­tion when the crown is pulled.

The 39.9mm watch is pow­ered by the man­u­ally wound L094.1 man­u­fac­ture cal­iber. A small tri­an­gu­lar in­di­ca­tor on the dial turns red 10 hours be­fore the 42-hour power re­serve runs out, serv­ing as a re­minder to rewind the watch.

The in­tri­cate con­stant-force es­cape­ment and zero-re­set mech­a­nism can be ob­served through the sapphire-crys­tal case­back. The aper­ture re­veals how the re­mon­toir spring of the con­stant-force es­cape­ment re­ceives fresh en­ergy from the main­spring bar­rel ev­ery sec­ond to power the es­cape­ment at the same rate. Just be­low it, un­der a trans­par­ent jewel bear­ing, a star con­nects to the fourth-wheel ar­bor that con­trols the jump­ing sec­onds se­quence.
