BREAK­THROUGH: 1815 RAT­TRA­PANTE PER­PET­UAL CAL­EN­DAR

A. Lange & Sohne has tran­scended watch­mak­ing with the 1815 Rat­tra­pante Per­pet­ual Cal­en­dar. It fea­tures the tech­ni­cal rat­tra­pante or split-sec­ond chrono­graph func­tion that mea­sures lap times, a per­pet­ual cal­en­dar de­signed to re­main cor­rect till the year 2100, and a lu­nar dis­play that only needs cor­rect­ing ev­ery 122 years. Time al­most never stops with this watch.

The vis­ually stun­ning timepiece has an amaz­ing new move­ment made up of 636 parts. The split-sec­ond mech­a­nism has two in­di­vid­ual col­umn wheels (en­sur­ing pre­ci­sion and ac­cu­racy) – one for the chrono­graph and one for the rat­tra­pante, which is ac­ti­vated by the but­ton at 10 o’clock. All this mag­nif­i­cence is vis­i­ble through the sap­phire-crys­tal case­back and ranks among the most fas­ci­nat­ing of watch move­ments.

On the el­e­gant dial are Ara­bic nu­mer­als, a rail­way-track minute scale, gold and blue hands as well as four round sub­sidiary di­als in a clover-leaf con­fig­u­ra­tion.

De­spite its com­plex mech­a­nism, the 1815 Rat­tra­pante Per­pet­ual Cal­en­dar boasts a rel­a­tively pe­tite, clas­sic de­sign – a sig­na­ture of the 1815 watch fam­ily that has its roots in the brand’s grand pocket-watch tra­di­tion. Avail­able in a plat­inum or rose gold case, this timepiece is a def­i­nite musthave for col­lec­tors who value both form and func­tion.
