This watch is the epitome of the Vallée de Joux’s simplicity. The Brassus brand has housed a new self-winding 242 calibre with an exceptional 12-day power reserve in a double stepped case, typical of the ancestral watchmaking area. The ultra-thin movement (6.10mm) with an oscillating weight and integrated power reserve indicator – both visible from the back – has a silicon spring and pallet fork horns. The flying tourbillon at 12 o’ clock seems to leap from its display like lace fluttering on a striking white Grand Feu enamel dial. The finesse in the finer details (e.g. hand-guilloché bridges) and the movement’s complexity (e.g. 243 components) make it a classic in the Swiss watchmaking world. It is available in 18 carat red gold for 119,000 CHF or a numbered platinum limited edition for 139,000 CHF.
