Dual Time Rainbow

The AHC Dual Time “Rainbow” is one of the most visually striking executions of Vladimir Négault's debut creation, produced in an ultra-exclusive edition of just 9 pieces worldwide. While retaining the elegant dual-time architecture that defines the Dual Time collection, this version transforms the watch into a vibrant showcase of colour, light, and transparency through its extraordinary rainbow sapphire crystal dial.

The centrepiece of the watch is undoubtedly the multi-layered sapphire dial, where a vivid spectrum of colours flows seamlessly around the circumference, creating an ever-changing display as light passes through the transparent crystal. The rainbow gradient transitions through rich blues, greens, yellows, oranges, reds, and violets, producing remarkable depth and visual dynamism. This colourful sapphire construction allows the dial to appear almost suspended above the movement, creating a striking architectural effect unique to this edition. Above, the signature day/night display provides home time indication, while the central display presents local time, ensuring the watch remains highly functional despite its artistic presentation.

The watch is housed in a matte-blasted titanium case measuring 41mm in diameter and only 9mm thick, offering exceptional comfort and wearability. Beneath the dial sits Atelier Haute Complication's proprietary German Silver calibre, comprising 187 components (220 cased) and 28 jewels. Each movement is meticulously hand-finished with sandblasting, circular graining, and hand-bevelled edges. Operating at 21,600 vibrations per hour (3Hz), the movement delivers a power reserve of approximately 42 to 45 hours.

Combining independent watchmaking, architectural design, and an extraordinary explosion of colour, the AHC Dual Time “Rainbow” is a rare and highly collectible expression of contemporary horological artistry, made even more desirable by its production of only 9 pieces worldwide.
