475 Parts. 440 Hours. No Room for Error.

Girard-Perregaux has put together a watch that’s more about the craft than the count.

This piece combines a minute repeater, tourbillon, and a new self-winding system into one 475-part openworked caliber. It takes nearly 440 hours to assemble and decorate. The artisan's initials are subtly included on the skeletonized movement—a quiet nod to the hands behind the work.

The case is 18kt rose gold, measuring 46mm by 17.9mm. It features an AR-coated "glass box" sapphire crystal and a sapphire display back. Water resistance is minimal at 30 meters, but let's be honest, this isn't for swimming.

Inside, you’ll find the Swiss automatic GP09530-2198 caliber with 47 jewels, running at 21,600 vph and offering a 60-hour power reserve. A white gold micro-rotor handles winding duties. The movement is hand-decorated with over a thousand hand-polished chamfers and nearly 300 interior angles. Functions include hours, minutes, small seconds on the tourbillon, and minute repeater.

The dial keeps it simple with a rose gold inner bezel ring and applied hour markers filled with luminescent material. Rose gold openworked hands match the theme.

It’s paired with a black rubber strap that has a fabric effect and secures with an 18kt rose gold triple folding clasp.

Price is set at $590,000. Not limited edition, but production is under eight pieces per year. You’ll know if it’s for you.
