Time will stand still at the SIHH when Vacheron Constantin will unveil its Malte Tourbillon Regulator. Offered in 18 kt gold and platinum, this perfectly balanced tonneau case packs a manual-winding caliber 1790R. It has 27 jewels, beating at 18,000 BPH and a power reserve of 40 hours. Some of the exceptional finishing operations on the 1790R movement can only be done by hand, particularly in the case of the bar, which takes 11 hours to hand-finish. Measuring a 40mm X 50mm, the crystal is sapphire.
The dial is 18kt gold done in five kinds of finishing for optimal reading: snailed, guilloched, opaline, vertical satin-finishing, and circular satin-finishing. The dark-blue or brown hand-stitched, saddle-finish, square-scaled alligator leather strap can be clasped with a Platinum or 18kt gold buckle that features a half Maltese cross motif.
