Jaquet Droz Grande Seconde Tourbillon Aventurine (Ref. J013014270) Swiss Watches

While Jaquet Droz is quite prolific when it comes to design of their extremely beautiful timekeepers, it is the one with figure eight-shaped off-centered layout that always gets the most attention. In this respect, the new Jaquet Droz Grande Seconde Tourbillon Aventurine (Ref. J013014270) will most probably be a triple win for the Swiss watchmaker: not only it incorporates the symbol of infinity on its dark-blue, star-studded dial, but the watch also sports a stunningly executed tourbillon that also acts as a small seconds hand, as well as sports whole 382 diamonds totaling almost 1.9 carats and decorating its medium-sized white gold body, the dial and even the folding clasp on its hand-made leather strap.




Aventurine, a sort of quartz, which is known for its star-like mineral inclusions and is becoming more popular among watchmakers and jewelers, again plays a leading role.

With its deep blue color that does such a great job mimicking a night sky, the mineral looks especially stunning when combined with white gold and hundreds of diamonds that compose the timekeeper’s body and main elements of the dial.

Traditionally for the Swiss-based brand, the dial of the watch is decorated with a figure eight-shaped cutout that houses a natural white mother-of-pearl inlay and tourbillon carriage. The three blued steel hands are nicely matched by three blued steel screw heads making the watch look even more expensive.

According to official info, the device is powered by their own Caliber 25JD in-house movement. Featuring automatic winding and sporting an impressive power reserve of whole week, this mechanism is identical to that that powers the gorgeous Jaquet Droz Grande Seconde Tourbillon Automatic (Ref. J013033200) that the company has first presented back in 2011 and started selling in 2012.

The main difference between the two calibers is, of course, the way their oscillating weights are decorated. This new version of the engine has its winding rotor adorned with another block of aventurine with extra seven-spoke gold stars giving it an even more refined look.

The painstakingly decorated tourbillon carriage that also houses a blued steel small seconds hand seems to be the same, which is great since it looks perfect to yours truly. From where I stand, this is one of the most well-balanced and exquisitely, um, beautified component that I have seen in years.

Since the watch seems to have been designed for the better part of humanity, it is offered in a significantly smaller body that now measures just 39 millimeters in diameter and is only a trifle thicker than 13 millimeters from top to bottom.

When it comes to timekeepers of this caliber, ergonomics is possibly the last thing that many people think about, but Jaquet Droz did its homework here, too: the watch is as easy to read (at least when you have adequate lighting), as it seems to be comfortable to wear.




Frankly, I can’t find any flaw to its design. Well, perhaps, its only problem is that the watch is limited to just 28 pieces, which makes it tough for those who don’t have such an impressive pile of cash on their accounts. According to JD’s press service, the watch will be offered at 118,700 CHF, which roughly converts to $132,000 USD or €98,000.

While the price of the device seems to be prohibitive for most buyers, the timepiece seems to be worth every penny that the Swiss brand asks for it: it is probably one of the most collectable timekeepers in this price range.
