Description

The present watch is the Patek Philippe Ref. 5101R, a landmark rectangular “10‑Day Tourbillon” that united, for the first time at Patek Philippe, a tourbillon regulator with twin tandem barrels delivering 240 hours of power reserve. Rendered in 18k rose gold and measuring 51.5 × 30 mm, the stepped Art Deco case features a sapphire display back to reveal the hand‑finished movement.

The dial presents refined clarity: a grey ground with applied Breguet numerals and silvered sub‑dials—power reserve at 12 o’clock and running seconds at 6 o’clock. Elegant feuille hands complete the composition, underscoring the piece’s formal character.

Inside, the hand‑wound calibre TO 28‑20 REC 10J PS showcases Patek Philippe’s chronometric craft. The tourbillon, assembled from 72 individual parts, is paired with two mainspring barrels in series to provide a steady torque over 10 days, emphasizing long‑duration precision. Finishing is executed to haute horlogerie standards, visible through the sapphire back.

The watch is fitted to a leather strap with an 18k pink‑gold buckle, aligning with the case’s warm tone. Functions are focused and pure: time with small seconds, and a prominent power‑reserve indication supporting the extended running autonomy.
