Patek Philippe Introduces Grande and Petite Sonnerie “Only Watch”

Only Watch has finally revealed the watch that everyone has been waiting for: the Patek Philippe Grande and Petite Sonnerie Ref. 6301A-010 “Only Watch” that will be auctioned by Christie’s on May 10th in Geneva. Based on the standard version of Patek Philippe’s clockwatch which is the second most complicated watch in the brand’s catalogue.

Featuring a Rare Handcrafts dial with a hand-guilloche swirling pattern visible beneath a Grand Feu blue-green enamel (flinqué enamel technique) the dial. 0.45-carats-worth of diamonds are festooned onto the dial in the form of 12 baguette-cut hour markers. A chapter ring encircles the outer dial, enveloping the 6-‘clock jumping seconds and power reserve displays, complete with white gold faceted Dauphine hands. Additionally, the sapphire crystal case-back bears the metalized inscription “Only Watch 2024.”  

The watch has the same GS 36-750 PS IRM movement comprising 703 parts, as found in the regular production model.  The movement has rhodium plating, luscious Geneva stripes, and immaculate hand-beveled and polished edges.  It has a 72-hour power reserve, and a Strikework power reserve of 24 hours (with its power reserve indicator on the right of the dial).  Two patented innovations are linked to the striking mechanism and one to the jumping small seconds mechanism (at 6 o’clock).

The case is identical to that of the standard version in dimensions at 44.8 mm by 12.3 mm, making it one of Patek Philippe’s largest watches. This unique version, however, has a steel case, which will make it substantially lighter and more easily wearable than the regular production model that is only available in platinum.

Accompanied by a patinated alligator strap in a dark blue-green, the timepiece is estimated to sell between $1,644,631 – $1,973,558 USD. The upcoming auction will be taking place in Geneva on May 10.
