MORE THAN TIME

Patek Philippe introduced the annual calendar in 1996, and in 2022 it paired it with Travel Time for the first time in the 5326G. The result is a watch that keeps track of both the calendar and the itinerary. Day, date and month sit in windows across the dial and only need adjusting once a year, at the end of February. A second hour hand follows home time, with separate day and night indicators for home and local, and the pushers on the left flank move local time forward or back an hour without disturbing the minutes. A moon phase sits at six. The dial is a textured charcoal gray with Arabic numerals, set in a 41mm white gold case. Excellent condition, 2023, box and papers. A traveler's watch that dresses like a dress watch, and one of the most complete everyday Pateks in the Vault.

The chronograph is the most familiar complication there is, and Audemars Piguet's 38mm Royal Oak Chronograph is one of its most polished forms. Reference 26715ST keeps the octagonal case, integrated bracelet and exposed screws of the original, then sets the bezel with brilliant-cut diamonds. The light blue Grande Tapisserie dial carries two counters and a date, laid out so the face reads as a Royal Oak first and a chronograph second. Inside is the self-winding Calibre 2385, a column-wheel chronograph that gives the pushers a clean, precise feel. The 38mm size sits comfortably on a smaller wrist and works for anyone. Hand-brushed and polished steel throughout. Excellent condition, 2024, box and papers. Proof that a working complication can also be the most elegant thing in the room.

The GMT-Master was designed in 1954 for Pan Am pilots who needed to keep track of two time zones at once, and the principle has not changed. A fourth hand makes one turn every 24 hours and reads against the bidirectional bezel, so home and local time are always in view. In the current generation the hour hand jumps independently, which means setting local time on arrival takes a few seconds and never stops the watch. Reference 126711CHNR is the one collectors call the Root Beer, for the brown and black Cerachrom bezel that recalls a 1970s original. The case and bracelet combine Everose gold and Oystersteel around a black dial. 40mm, self-winding Calibre 3285 with a 70-hour power reserve. Brand new, 2026, box and papers. The most practical complication here, and probably the one that gets worn most.

Long before the current Odysseus became a steel sports watch, Jaeger-LeCoultre used the name for a line of round, classically proportioned dress watches, and this perpetual calendar is one of them. The rose gold case measures 36mm, with a white dial laid out across four subdials for day, date, month and moon phase, plus a small 24-hour indicator. A perpetual calendar accounts for months of different lengths and for leap years, so once it is set it needs no correction for decades, as long as it keeps running. The self-winding movement comes from a manufacture that has produced more calibers than almost any other in Switzerland. Excellent condition, sold as watch only. At PHP 780,000 it is the most approachable way into high complication in the Vault, and a reminder that some of the best value in watches sits a generation back.

Audemars Piguet has been making perpetual calendars since the 1950s, and the Royal Oak version is the one that turned the complication into something you wear every day. This 41mm reference 26609TI was made for the Chinese market and limited to 88 pieces. It was the first in the 41mm perpetual line built entirely in Grade 5 titanium, case and bracelet, which makes it noticeably lighter than its steel and gold siblings. The slate gray Grande Tapisserie dial carries day, date, month and moon phase, plus a week-number track picked out by a red hand, a quiet reference to what the color means in Chinese culture. Inside is the ultra-thin self-winding Calibre 5134, which accounts for short months and leap years without correction until 2100. Excellent condition, 2020, box and papers. A rare Royal Oak that rewards a closer look.

The RM 11 has been Richard Mille's everyday complication since the first version arrived in 2007, and the 11-05 adds the one thing a frequent traveler asks for, a second time zone. On top of the flyback chronograph, which stops, resets and restarts the timer with a single press, it carries an annual calendar with a large date and a month display that needs adjusting only once a year. The GMT hand is set through a dedicated pusher on the case flank, and every function can be followed through the skeletonized automatic movement. The case is Carbon TPT, layers of carbon fiber pressed and cured into a material that is light, tough and slightly different on every piece. At 50mm it wears smaller than the number suggests, thanks to the curved tonneau shape. This example dates from 2021. It is the most complicated watch in the edit, and the least precious about it.

The Sky-Dweller is the most complicated watch Rolex makes, and also one of the easiest complicated watches to live with. It combines two functions travelers actually use. An off-center disc shows home time in 24-hour format while the main hands follow local time. The Saros annual calendar, named after an astronomical cycle, reads the month through twelve small apertures around the dial and only needs correcting once a year, at the end of February. Everything is set through the Ring Command bezel, which turns to select the function and lets the crown do the rest. This reference 336934-0005 pairs a bright blue sunray dial with a fluted white gold bezel and an Oystersteel case at 42mm. Brand new, 2026, box and papers. A modern classic that asks you to read the manual once and then never again.

The World Time is Patek Philippe's answer to a problem most travelers now solve with a phone, and it solves it far more beautifully. Twenty-four city names ring the dial, a 24-hour disc turns beneath them, and a single pusher at ten o'clock advances the local hour while every other zone follows. The movement is Calibre 240 HU, built on Patek's ultra-thin micro-rotor, so the white gold case stays at a dress-watch 38.5mm. What sets the 5231G apart is the center. In place of guilloché, Patek uses a hand-made Grand Feu cloisonné enamel map, here showing Oceania and Southeast Asia, each line of gold wire laid by hand and fired in the kiln. No two are exactly alike. This example is from 2023, in excellent condition, with box and papers. It is the rare complication that is as good to look at as it is to use.
