Pre-Owned Girard-Perregaux Traveller ww.tc Power Reserve 18K Rose Gold — Grey Dial, Full Set Dated 2007 (Ref. 49850-52-251-BA6A)
In 1931, a Geneva watchmaker named Louis Cottier patented a mechanism that let a single watch tell the time in every major city on the planet at once. Every modern world-time wristwatch — Patek’s, Vacheron’s, this Girard-Perregaux — is still built on the same rotating ring he drew.
Available now at Black Tag Watches (Aventura, Florida), this 2007 example — reference 49850-52-251-BA6A — is cased in 18K rose gold with a grey world-time dial, powered by the manufacture calibre GP033G0, and offered complete with its original Girard-Perregaux presentation box and certificate card dated 2007.
What Is the Girard-Perregaux Traveller ww.tc Power Reserve?
The Cottier World-Time Mechanism
The world-time complication was not invented in 2000, or in the 1980s, or in any of the eras its contemporary market presence might suggest. It was invented in 1931 by the Genevan watchmaker Louis Cottier, who filed a Swiss patent for his “Heures Universelles” mechanism that year and spent the following three decades building world-time movements for Vacheron Constantin, Longines, Rolex, and — most consequentially — Patek Philippe, to which he delivered roughly three hundred and eighty movements between 1937 and his death in 1966. The mechanism Cottier drew — a central dial for local time, surrounded by a counter-rotating 24-hour ring geared to track the world’s time zones — remains the architecture every modern world-time wristwatch is built on, including this Girard-Perregaux.
GP's ww.tc and Its Place in the Modern World-Time Field
Girard-Perregaux’s ww.tc (“World Wide Time Control”), launched in 2000 and patented as the maison’s own modern expression of the Cottier mechanism, is one of the handful of contemporary manufacture world-timers that extends the complication into the twenty-first century. Its launch year is significant: 2000 was the same year Patek Philippe reintroduced its own world-time line with the reference 5110 after a thirty-four-year dormancy following Cottier’s death. For collectors of pre-owned world-time watches, the GP ww.tc is one of the few modern world-time complications patented and produced entirely in-house by its maison — a distinction that places it alongside the better-known Genevan references on technical merit.
Dial & Case Design: Rose Gold, Two-Crown World-Time Layout
Case Construction and the Second Crown
The 41mm case is rendered in 18K rose gold and stands only 11mm thick, with polished flanks and short tapered lugs framing a two-crown configuration specific to the reference: the standard winding crown at 3 o’clock, and a second signed rose gold crown at 9 o’clock that operates the world-time function by rotating the cities ring to align the user’s current city at the 12 o’clock position. The second crown is the reference’s most immediate functional signature — the interface through which the entire world-time complication is set.
The Grey World-Time Dial
The dial is where the complication reads. An outer ring of twenty-four reference cities — from New York and Chicago in the Americas through Paris and London to Tokyo, Sydney, and Auckland in the Pacific — covers every full-hour time zone from GMT−11 through GMT+13, and an inner 24-hour ring rotates counter-clockwise once per solar day with daylight hours against a white field and the nocturnal hours against dark. A grey central dial carries large applied rose gold Arabic 3, 6, 9, and 12 numerals, with the Girard-Perregaux signature printed beneath 12. A power reserve indicator sits above the dial centre with a 46-hour scale, a framed date aperture sits between 1 and 2 o’clock, and a small-seconds sub-dial sits at 9. The composition is dense but ordered: every function occupies its own geometry, and the eye finds each at a glance.
Movement: Manufacture Girard-Perregaux Calibre GP033G0
One of the Few Remaining Vertically-Integrated Manufactures
Inside is the manufacture Girard-Perregaux calibre GP033G0 — an automatic movement of 27 jewels running at 28,800 vph (4 Hz) with a 46-hour power reserve, developed and produced in-house at the maison’s La Chaux-de-Fonds facility. Girard-Perregaux is one of the oldest continuously-producing Swiss watchmaking manufactures — the maison traces its origin to 1791 in the workshop of Jean-François Bautte and takes its current name from the 1854 acquisition by Constant Girard — and its modern operation is one of the smaller circle of Swiss houses that remains a vertically-integrated manufacture rather than relying on supplier ébauches. For buyers evaluating pre-owned world-time watches, that in-house status is a substantive credential, not a marketing line.
Coordinating Six Functions
The GP033G0 drives the world-time cities ring, the inner 24-hour ring, the central time display, the power reserve indicator, the date, and the small-seconds — a specific coordination that requires the ww.tc patented module to work in concert with the base calibre’s going train. The movement is finished with Côtes de Genève on the bridges, perlage on the mainplate, and a signed rotor visible through the sapphire display caseback. For a 2007-dated manufacture world-timer at this price band, the GP033G0 is exactly the class of calibre that justifies the reference’s position within the serious modern world-time market.

Condition, Provenance & Documentation
Full Original 2007 Delivery
Condition is mint. Provenance is complete: the watch is offered with its original Girard-Perregaux presentation box and certificate card dated 2007. The strap is a pre-owned alligator in good condition rather than a factory-new replacement, which is straightforward provenance for a watch of nearly two decades’ age; the signed rose gold folding buckle, the meaningful provenance signal at the strap level, is present and original. For a 2007 Traveller ww.tc with full original documentation and the signed buckle intact, this is the appropriate acquisition configuration for the reference.

Why Buy a Pre-Owned Girard-Perregaux Traveller ww.tc?
A Serious Manufacture World-Timer the Market Overlooks
The Traveller ww.tc Power Reserve occupies a specific corner of the contemporary world-time secondary market — recognised by collectors who track the serious manufacture world-timers alongside the better-known Patek 5110 / 5130 / 5230 lineage, and largely bypassed by buyers whose world-time familiarity stops at the Genevan references with broader cultural recognition. Girard-Perregaux’s ww.tc is one of only a few modern world-time complications patented and produced entirely in-house by its maison, and its 2000 launch placed GP squarely within the small contemporary world-time field alongside Patek’s own reintroduction that same year. The rose-gold Traveller ww.tc with power reserve is one of the more completely-specified configurations in the line.
Full Set, Below Retail, Historically Grounded
Full-set examples with original documentation from within the production window are increasingly hard to source. Against contemporary rose-gold world-time retail — and against the current Patek 5230, Vacheron Overseas World Time, and other manufacture world-time references — this Girard-Perregaux Traveller ww.tc offers direct entry into a serious patented manufacture world-timer at a level that rewards horological literacy over badge recognition, with a complete original delivery from within the production window and the signed rose gold buckle intact. For the collector who values the in-house world-time mechanism over the more culturally recognised names, it is one of the quieter strong propositions in the category.
