Sta­ble Mate

Bespoke - - SHOOT -

In­spired by Baume & Mercier mod­els from the 1950s and con­ceived as a con­tin­u­a­tion of their Clas­sima line, the ver­sa­tile and un­der­stated Clifton model has re­mained one of our favourites B&M’S ever since it de­buted in 2013. And, though it al­ready plays host to an in­cred­i­bly wide va­ri­ety of com­pli­ca­tions, it gets an­other this year in the form of the 12,000 USD Clifton Man­ual 1830 Twin­spir. This state-of-the-art move­ment cen­tres around a to­tally orig­i­nal and pro­pri­etary sil­i­con hair­spring, de­vel­oped by the Richemont Re­search & In­no­va­tion team. First a lit­tle back­ground though. A hair­spring, or bal­ance spring, is a spring at­tached to the bal­ance wheel in me­chan­i­cal time­pieces. It causes the bal­ance wheel to os­cil­late with a res­o­nant fre­quency, which con­trols the speed at which the wheels of the time­piece turn, and thus the rate of move­ment of the hands. In vin­tage watches, the hair­spring was of­ten made of steel wire but more re­cently it has been made from a va­ri­ety of dif­fer­ent al­loys, the most com­mon be­ing Ni­varox. The new Clifton Twin­spir’s spring goes its own way how­ever with a new sil­i­cone com­pos­ite ma­te­rial that al­lows it to not just be im­mune to tem­per­a­ture fluc­tu­a­tions, but cor­ro­sion and mag­netism too. The net re­sult is a more even and sta­ble chrono­met­ric per­for­mance, with far greater long-term ac­cu­racy. Ca­pa­ble of run­ning for 90 hours, the 18-karat red gold Clifton Man­ual 1830 watch is 42mm wide and 8.9mm thin, with a wa­ter-re­sis­tance rat­ing of 50 me­tres.
