Jaeger-LeCoultre no. 1660 ring watch on the finger

Give Me Five! Rare And Unusual Ring Watches

A ring watch is a very rare sight in horology. This delicate style of timepiece is dependent upon a masterful set of artisans as, to accommodate the dainty size needed to fit on a finger, the mechanics must be much smaller. While ring watches might be rare, they’re not unheard of. Here we show you five – well, six – quite different ring watches, one modern from Baselworld 2015 while five are historical pieces.

The panther is Cartier’s most famous animal. But why is this so, and how has this ‘beastly’ line managed to remain in the watch and jewelry collection for more than 100 years? A look at the relationship between Louis Cartier and “the Coco Chanel of jewelry” Jeanne Toussaint sheds some (spotted) light on the first watch design, the Art Deco painting that inspired the collection, and the popularity that propelled it.

Parting shot: G.N. Papi No.1 pocket watch

Exclusive: The Giulio Papi No. 1 Pocket Watch

Sometimes persistence pays off. After a few well-placed questions, the shopkeeper brought out a relatively innocent looking skeletonized pocket watch. With a wry smile, he suggested that the buyer take a look at the tiny lug, leaving my friend flabbergasted. “G.N. Papi No.1” is a clear reference to Giulio Papi. The legendary watch industry figure who leads Audemars Piguet Renaud & Papi and now my friend has stumbled across what could be his very first timepiece from 1984.

Here’s Why A Watch Is More Like A Motorcycle Than A Car

This is the first installment in a new series of articles focusing on a single concept. I’m calling it “Here’s Why.” Here I explain here’s why a watch is more like a motorcycle (and an iPod) than a car. To help me find the answers, I spoke to a few serious motorbike riders who also love mechanical watches, such as Bremont ambassador Charley Boorman and motorcycle enthusiast and watch journalist Keith Strandberg. The answers will surprise you.

Dramatic Scenery On And Off The Wrist: Panerai Classic Yachts Challenge At British Classic Week

I have been an admirer of Panerai since the late 1990s, so getting a chance to go out to the Isle of Wight for the British Classic Week in Cowes, where Panerai is the time partner for the Classic Yachts Challenge, was a fantastic experience. I had the chance to see and photograph a number of recent Panerai releases in their natural habitat over the race weekend.

The Urwerk Opus 5 For Harry Winston That Almost Was

The Opus 5 by Felix Baumgartner/Urwerk for Harry Winston is one of the best of this series of exceptional timepieces.

Titanium cased Romain Gauthier Logical One Black

Back In Black: Romain Gauthier’s Logical One Black

Romain Gauthier’s Logical One is a masterpiece of complicated mechanics, boasting − as with all of the models in his collection − a level of finishing rivaled only by the likes of Philippe Dufour, Greubel Forsey, and Kari Voutlainen. That’s high praise, indeed. With its four patents, Logical One delivers what it promises: a re-imagined complication laid out very logically. And the most recent edition of the timepiece taking home the 2013 Grand Prix d’Horlogerie de Genève prize for best men’s complication is a surprising all-black version.

Having the chance to wear the H. Moser & Cie. Endeavour Perpetual Calendar for several weeks reminded me a great deal of the evening the brand launched in Schaffhausen, Switzerland.

Mechanical Computers From Then To Now: Greubel Forsey Quantième Perpétuel à Équation

Calculating large numbers is a pain if all you have handy is your brain and a pencil. This is why people have created systems and objects to make the process easier. The Greubel Forsey Quantième Perpétuel à Équation has a mechanical computer that calculates the dates for the perpetual calendar and equation of time. This is a complete departure from the traditional perpetual calendar mechanism.
