Neuhaus Janus DoubleSpeed Silver Limited Edition

Just before the MUNICHTIME show (2-4 November, 2012), German watch brand Neuhaus presents a new version of their extraordinary Janus DoubleSpeed mono-hand watch with a silver dial. Of course, the new dial is not simply a silver plate with black numerals printed on it: The new player on the watch market has once more applied the Janus principle in a way similar to the black predecessor model. While its brightness remains unseen during the day, it completely unfolds at night time where it is needed. This amazing dual nature of the watch resembles Janus, the two-faced Roman God.

To achieve this, separate pockets for each numeral are cut with highest precision into the light silver dial and are then filled with light Super-LumiNova. Afterwards, the numerals are printed in black right on the luminous paint. This technique results in a design where you see just the black numerals while the light paint remains hardly noticeable in daytime. At night, however, the dial and the numerals stay dark, while the brightly glowing numeral outlines become visible.

Mono-hand watches come without the minute hand; there is just an hour hand. The hour hand of the Janus DoubleSpeed moves at double speed, that is, it goes round the complete dial within just six hours. The dial displays an innovative 6-hour scale with double-sized segments, with each mark representing two times 6 hours apart. This results in a degree of readability unprecedented among mono-hand watches.

Even without the second hand, you know at a glance that the watch is running: Through three small cutouts in the dial, you can see a rotating disc featuring black and white sectors. Plus the innovative night-vision design becomes visible just when you need it—in the dark. The Janus DoubleSpeed is driven by a classic hand-winding movement that is visible through the glass bottom. That movement has been converted to double speed with outstanding watchmaking expertise. Only 99 silver-dial items will be available worldwide.

JANUS DoubleSpeed by NEUHAUS Inventing Timepieces

NEUHAUS Inventing Timepieces is a new, independent watch based in Augsburg, Germany. Founded in 2009 by Manuel Neuhaus, the company manufactures high grade exclusive watches in limited editions for watch aficionados.

The JANUS Double Speed model by NEUHAUS is a highly innovative single hand watch that comes just with an hour hand, which winds in double speed, meaning 360° in six hours. For each hour there are two cyphers, six hours apart from each other. It is up to you if it is four o´clock or ten o´clock. The hour of course is divided in half hours, quarter hours and five-minute sections. These sections are, because of the double speed, twice as big as normal and therefore directly legible.
Instead of using a sweep hand, JANUS Double Speed is provided with a new kind of running indication. At first sight you can make sure if your JANUS is operating. A black and white disc turning beneath the watch dial indicates the change of colours which takes two seconds.
The indication on the dial is well luminous, though during day time it stays almost invisible and doesn’t disturb the delicate design of the watch dial. The double-faced roman god Janus who gave the watch its name, symbolises this deliberate difference between day- and night view. At night, the five-minute sections aren’t available. The smallest unit then are the quarter hours.

To wind up the watch, turn the crown forwards. After approximately 30 twirls the maximum is reached and the mechanism will block. To adjust the time, gently lift the crown outwards with your fingernail until it clicks into place. The time can now be adjusted by turning the crown. When done, you simply press the crown back into its initial position.

Each JANUS DoubleSpeed single hand timepiece is supplied with a high quality stainless steel Milanese bracelet. A black leather bracelet is also available as an option. The length of the steel bracelet is individually adjustable. The JANUS DoubleSpeed has water resistance up to 5 ATM. All NEUHAUS JANUS DoubleSpeed watches come with a unique crown featuring a silicone ring for an ergonomic grip and the emblem on front side.

he case back has engraved the year of creation, a design model number as well as a continuous serial number. In addition, every watch is consigned with an authenticity certificate containing the same information. NEUHAUS Inventing Timepieces issues 24 month guarantee on JANUS DoubleSpeed, starting from the date of purchase.
