The entire calibre and case are hand finished, with traditionally buffed and polished corners, drilled and hand-polished balance bridge and sweep second cock,
escapement wheel on black-polished endstones, rounded and moveable Geneva hairspring stud holder, moulded, ringed and bevelled wheel and intermediate wheels,
and black-polished and hand-blued screws. The hour, minute and second hands are rounded by hand and then blued and lacquered.
The power reserve and selector dial is made of black-polished steel adorned with a lacquered engraving. The double barrels linked
in parallel are bevelled and engraved by hand. Each calibre leaving the Alchemists’ workshop is then individually numbered.
The Cu29 is a creation that can be highly personalized by allowing the customer to select a dial from our collection of different stones.
Each stone has been selected by the Alchemists for its lithotherapeutic benefits when combined with those of the Cuprum.
The Cu29 is a timepiece equipped with a variable inertia balance with weight screw situated at 8 o’clock.
Just above, between 10 and 11 o’clock, the power reserve is
indicated by a cursor moving along a peripheral gear bar indexed from 0 to 72 hours.
On the opposite side, between 2 and 3 o’clock, the selected function is indicated: W (Wind) or S (Set). The hour dial, made from “Grand Feu” enamel or stone, is placed at 12 o’clock, and displays the hours (red hand) and minutes (white hand), while the seconds are displayed off-centre at 6 o’clock. The ring, calibrated into 60 trailing seconds, covers the two barrels of the Cu29.
Manual-winding mechanical manufacture movement, engraved and hand-bevelled double barrel linked in parallel, suspended “moustache” dual pawl winding. Ébauches in Cuprum 479, titanium and stainless steel.
