Vacheron Constantin’s Overseas Perpetual Calendar Ultra-Thin has always sat in a rare space between sport-watch ease and high-complication watchmaking.
For the Overseas collection’s 30th anniversary, the maison has given the model a quieter kind of presence, led by a pale azure lacquered dial that changes the mood of the watch without simplifying what it does.
The result is still a perpetual calendar in white gold, limited to 200 pieces, but it feels less formal and more open on the wrist.

At a glance
- Vacheron Constantin has introduced a 200-piece Overseas Perpetual Calendar Ultra-Thin for the collection’s 30th anniversary.
- The watch pairs a 41.5mm white-gold case with a pale azure lacquered dial, perpetual calendar display and moon phase.
- Its automatic 1120 QP/1 calibre is 4.05mm thick and needs no calendar correction until 2100.
A lighter azure dial changes the Overseas mood
The defining update is the dial, which moves away from the deeper navy often associated with the Overseas line.
Its azure tone is lighter and less saturated, giving the perpetual calendar display a softer visual character.
That matters because perpetual calendars can easily feel dense, especially when day, date, month, leap year and moon phase are all competing for attention.

Here, the layout remains complete but the colour treatment gives the dial more breathing room.
The day of the week, date and month are arranged across three counters, while the leap-year indication appears at 12 o’clock.
The moon phase sits at 6 o’clock, with a disk that echoes the dial’s blue tone rather than introducing a sharper contrast.

Ultra-thin watchmaking with a full calendar
Inside the watch is Vacheron Constantin’s automatic 1120 QP/1 calibre, a movement measuring just 4.05mm thick.
Despite that slim profile, it comprises 276 components and drives a perpetual calendar able to account for months of 28, 30 and 31 days, as well as leap years.
The calendar won’t require correction until 2100, a practical detail that speaks to the purpose of the complication as much as its prestige.
Through the sapphire crystal caseback, the movement reveals a 22k gold oscillating weight engraved with a compass rose.
White gold, integrated bracelet and strap flexibility
The case is crafted in white gold and measures 41.5mm across, with a height of 8.1mm.
Those proportions are central to the appeal of the watch, since the complication is housed in a case that remains notably slim.
The integrated bracelet is also made in white gold, reinforcing the model’s polished, precious-metal character.
Vacheron Constantin also supplies two rubber straps in white and blue jean, each of which can be swapped without tools.
That strap system keeps the watch aligned with the broader Overseas identity, where travel-minded practicality is part of the design language rather than an afterthought.
