The Ulysse Nardin GMT Perpetual Ref. 329-60 is a rare fusion of innovation, practicality, and precious-metal elegance. Produced in the early 2000s as a limited edition of 500 pieces in platinum (Pt950), it combines a perpetual calendar with a user-friendly dual-time GMT function, all housed in a substantial yet refined 42 mm platinum case with curved lugs and a sapphire exhibition back.

Its silver guilloché dial features bold white-gold Arabic numerals at the quarters, luminous markers, skeletonized blued-steel hands, and an arrow-tipped GMT hand pointing to the 24-hour scale. The perpetual calendar displays the day, date, month, and a two-digit year/leap-year window, laid out for easy reading. Notably, the + / – pushers at 4 and 8 o’clock allow the local hour to jump forward or backward in one-hour increments — a hallmark of Ulysse Nardin’s travel-friendly engineering.

Powering the watch is the in-house calibre UN-32, an automatic movement with a 48-hour power reserve, 34 jewels, and fine finishing visible through the sapphire caseback. Water resistance is 30 m, suited to its role as a refined travel companion.

Collectors seek the 329-60 for its blend of perpetual calendar complexity with intuitive GMT adjustment, the rarity of a platinum-cased complication limited to just 500 pieces, and its distinctive mix of practicality and high-horology craftsmanship — a testament to Ulysse Nardin’s forward-thinking approach to complications.
