Vacheron Constantin Overseas Chronograph Perpetual Calendar in pink gold

30/08/2012 | By Frank Geelen | 4 min read |

More then a year ago, in June 2011, Vacheron Constantin launched the most complicated watch in the Overseas collection. The first Overseas Chronograph Perpetual Calendar came in a titanium/steel case, one of the three choices of metals that Vacheron Constantin offers. Yesterday VC launched another version of the Overseas Chronograph Perpetual Calendar, but now in pink gold.

Because the photo of the VC Overseas Chronograph with deep blue dial, that we introduced yesterday, got so many positive responses, we show you the Overseas Chronograph Perpetual Calendar (or QP from Quantième Perpetuel like the French say), in exactly the same angle. A ‘dramatic’ view on a stunning timepiece!

To be honest, usually I’m a purist and therefore no fan of mixing styles. Since the Overseas is a chic, elegant and sporty styled watch, my first response on mixing this style with a perpetual calendar would be skeptical. However seeing the photos of the new Overseas Chrono QP didn’t leave any room for doubt, this is a stunning watch!

I can imagine this watch will not be worn during sports activities, something for which the watch was originally designed, I’m sure it looks good with either casual clothing or combined with a suit and tie. The combination of the pink gold case on a brown alligator leather strap gives this watch an extra boost of “chic”. And so does the combination of pink gold case with the grey/beige dial. The hands and hour-markers are accented with white luminescent substance ensuring readability even in the dark.

Inside the Overseas Chronograph QP beats calibre 1136 QP, that comprises of 228 parts. This caliber is a mechanical self-winding movement, just as one would expect from a sports watch. It oscillates at the rate of 21,600 vibrations per hour and is endowed with a power reserve of approximately 40 hours.

In addition to the hours, minutes and small seconds at 6 o’clock, Calibre 1136 QP powers the chronograph functions: central sweep seconds-hand, 30-minute counter at 3 o’clock and 12-hour counter at 9 o’clock. And of course it also powers the functions of the perpetual calendar: day of the week, date, 48-month counter (!!) with leap years as well as a moon-phase display.

The 18-carat pink gold 42 mm-diameter case, like all (men’s) Overseas models, is water-resistant to 15 bar (approximately 150 metres) and houses a soft iron cage protecting the movement from magnetic fields of up to 25,000 A/m. The case features design elements referring to Vacheron Constantin’s Maltese Cross emblem, that comes back in the bezel and embossed in the crown. The caseback also features the famous three-mast ship Amerigo Vespucci, like all Overseas models (and one Special Edition Panerai). Circular brushing around the case back with sun-ray brushing around the engraved ship that looks stunning. The amount of details and complex finishing applied of the case-back is impressive.

The Overseas Chronograph Perpetual Calendar is delivered with two straps: one vulcanized brown rubber and a brown alligator leather strap. Both straps are held together by a pink gold triple-blade, double-pusher folding clasp.

A really cool added value is that the Overseas Chrono QP is delivered with a luxurious presentation box that is equipped with a watch winder! This helps to keep the watch and its perpetual calendar to indicate the correct time and date, when it’s not on the wrist. A handy and very welcome extra, especially when considering that adjusting a perpetual calendar and moon phase is always kind of a hassle.
