Every Grand Complication Family
Grand Complications We Buy
The complication most closely associated with Patek Philippe's identity. From the legendary pre-war ref. 1526 and the pivotal 3940 — which restarted complicated wristwatch production after the Quartz Crisis — through the modern 5327, 5320, and 5236 in-line display. We buy every generation across all metals, and pay full recognition for early series and unusual configurations.
The most consequential complication lineage in watchmaking history. The ref. 1518 (1941) was the first serially produced perpetual calendar chronograph ever made — 281 examples, including four in steel. The 2499 (349 made over 35 years), the 3970, the 5970 (Thierry Stern's first design), and the current in-house movement 5270. Every series, every metal, purchased with full collector recognition.
The rarest of Patek's chronograph complications. The 5004 split-seconds perpetual calendar (1994–2012, approximately 200 made), succeeded by the current 5204 and the standalone 5370 split-seconds chronograph in platinum with black enamel dial. Each evaluated for series, dial originality, and caseback configuration.
Patek Philippe has dominated the minute repeater wristwatch since Philippe Stern introduced serially produced repeaters in 1989. We buy every generation: the early 3974 and 3979, the 5074 perpetual calendar repeater, the skeletonized 5304, the 5374 Haute Joaillerie, the 5207 tourbillon repeater, and the 5531 world time repeater with its Grand Feu cloisonné enamel dial.
The ref. 3939 (1992) was the first tourbillon wristwatch Patek Philippe ever produced — and the first serially produced tourbillon minute repeater by any manufacturer. Succeeded by the 5101 10-day power reserve tourbillon, the 5016 triple complication, the 5303 open-dial minute repeater tourbillon, and the 5316 retrograde perpetual calendar tourbillon repeater.
The most technically demanding watches in regular series production. The 5208 combines a minute repeater, mono-pusher chronograph, and instantaneous perpetual calendar in a self-winding movement — one of the most complex automatic calibers ever made. The 5308 adds a split-seconds mechanism to that formula. All configurations in white gold, rose gold, and platinum purchased.
Patek's astronomical complication — a rotating sky chart tracking the apparent motion of stars, moon phases and orbit, and sidereal time, all displayed on a single dial. The 5102 (first celestial, 2002), and the current 6102 in platinum and rose gold. Among the most visually spectacular watches in the entire Patek collection, and among the most underappreciated by collectors who focus on purely mechanical complications.
The most complicated Patek Philippe wristwatch ever made — 20 complications, 1,366 parts, including grande and petite sonnerie, minute repeater, alarm, perpetual calendar, and dual time zone. Seven examples of the 175th anniversary ref. 5175 were produced in 2014; the 6300 entered regular production shortly after. The Haute Joaillerie 6300/400G adds 409 baguette-cut diamonds. We are ready buyers at appropriate market levels.
Diamond-set and Haute Joaillerie Grand Complications — including the 5271P perpetual calendar chronograph with 80 baguette-cut diamonds, the 5374 Haute Joaillerie minute repeater perpetual calendar, the 5304/301R skeleton repeater with diamond bezel, and the 6300/400G Grandmaster Chime. Each evaluated with full gemological assessment of the setting, stone quality, and market position.

The Glenn Bradford Difference
Why serious collectors
call us first.
Glenn Bradford Fine Jewelry has spent four decades at the intersection of fine jewelry and horological expertise — buying, selling, and evaluating the world's most significant wristwatches from our flagship boutique in Southampton, New York. That depth of experience spans every era of watchmaking, every tier of the market, and every kind of seller: collectors who have spent decades assembling a collection, individuals who have inherited a single important piece, and clients who simply want a fair, expert, and discreet transaction.
Our particular strength is vintage and transitional-era watchmaking. We have been active in this market since before the secondary market for complicated Patek Philippe became what it is today, and we bring a level of nuance to early pieces that generalist buyers cannot match.
Whether you are selling a single piece or an entire collection, the process is the same: discreet, transparent, and grounded in genuine market knowledge. We are the first call for clients throughout the Hamptons, New York, and internationally — not because we are the most convenient option, but because we are the most knowledgeable one. That is a standard we have maintained for four decades and have no intention of changing.
