Laurent Ferrier and URWERK Arpal One
It’s neither a Laurent Ferrier watch nor an URWERK, yet the signatures of both firms appear on its back. The existence of this unexpected watch defies logic because it is the joint effort of two watchmaking companies that couldn’t be more different. Each bases its identity on the opposite ends of watchmaking’s stylistic spectrum. On one side, the expression of time-honoured traditions; on the other, an anarchic effort to overturn conventions. Laurent Ferrier and URWERK have created a piece of work that is unique, for only one-of-a-kind watches qualify to be sold at the Only Watch auction in aid of the battle against Duchenne muscular dystrophy.
This remarkable watch also offers a unique opportunity to witness two independent brands working together to produce a watch for the Only Watch 2017 sale. Laurent Ferrier has forged an enviable reputation as master of the definitive watch in the classic style. URWERK, on the other hand, has spent the last 20 years challenging the watchmaking world with its bold originality. The result of this extraordinary association is in front of your eyes.
You can well imagine the perfect, almost aerodynamic, curves coming to life in the confident strokes of Laurent Ferrier’s pencil. “It’s a cleanly cut watch. My friends know my love of cars, a predilection expressed in this watch. This new creation is like streamlined coachwork, fluid and without any affront to the eye,” he explains. Such a design demanded a special material. “For that we turned to the Cendres+Métaux company in Biel.” The case was shaped from an exclusive alloy called ARPAL+, specifically developed for this unique watch. ARPAL+ consists of 75% precious metals and resists wear and scratches better than white gold or steel. Its colour never fades, nor does it oxidise. This alloy was first developed for the electronics industry where it is much appreciated for its strength and because it is easily worked.
The polished case of the Only Watch by Laurent Ferrier and URWERK is what first catches the eye. It reflects light like no other and seems to sparkle. In contrast, URWERK’s movement was created with every restraint. Unlike the case, it is almost self-effacingly colourless. The four hours satellites are in a matt pearly grey with diamond-polished outlines while the hours and minutes markers are painted in white SuperLuminova.
The time is shown by four satellites, each bearing three hours numerals, which successively sweep past the track of minutes. This original and intuitive way of telling the time is aided by a cover in polyetheretherketone, a thermoplastic known as PEEK, which hides the satellites that are not engaged in indicating the time. The satellites turn on a hidden carrousel, at the heart of the successive passage of the hours. It’s no easy job to engineer the smooth and silent revolutions of a module that weighs 500 times as much as a conventional set of hands.
Arpal One by Laurent Ferrier and URWERK is powerd by the Selfwinding UR5.03 governed by a double turbine. The movement has 52 jewels, a 48 hours power reserve and runs at a frequency of 28,800v/h – 4Hz.
Dimensions of the case: width 40,9mm, length: 60,8mm, height: 20,7mm. The watch has pressure tested to 30 m/ 3 ATM.
