Set off to perfection within a 41 mm-diameter round case in 950 platinum featuring a concave bezel that intensifies its finesse, the engraved 2660/1 caliber is a mechanical hand-wound tourbillon movement with an exceptional 14-day power reserve. Its slightly off-centred hour and minute functions highlight the tourbillon carriage, coupled with a small seconds display. The power reserve is read off with a “dragging” or “trailing” hand that displays the remaining energy on a 280° sector. This larger surface than on traditional indicators enables a precise division into 14 days, themselves split into two 12-hour portions, thus enhancing the readability of the power reserve. The architecture of the 231-part movement features two large bridges, delicately hand-engraved with floral motifs and acanthus leaves, and visible through the sapphire crystal back of the case which is water-resistant to 30 metres. On the display side, the Métiers d’Art Mécaniques Gravées – 14-day tourbillon by Vacheron Constantin provides a stunning view of the tourbillon carriage shaped like a Maltese Cross and adorned with the most refined finishes. Swept over by anthracite-toned white gold hands and composed of two distinct parts, the sapphire crystal dial features frosted zones ensuring perfect readability of the engraved and inked small seconds and power-reserve graduations, while a slate grey ring bears the minute circle and a white gold Maltese cross. Revealed through the transparency of the dial, the stunning scrolling motifs and arabesques exalt the extreme beauty and rare elegance of an entirely hand-engraved work of art requiring more than a week’s work for a single movement.
