Our friends from Angular Momentum have just revealed their new Angular Momentum Longitude 12 Traveler Timepiece Concept hand-wound GMT watch that combines their beloved Verre Eglomise technique with a simple, but beautiful second time-zone complication that makes the wristwatch really stand out among hundreds of other contenders.
The photos are not very good (no offence intended, but they really need to hire a professional photographer to do the job,) but, to my understanding, the watch works as follows.
Using the aforementioned Verre Eglomise technique, AM’s artisans coat the inner side of the sapphire crystal with names of the cities that correspond to respective time zones.
Since watches are usually made on demand, the circle is positioned in such a way that owner’s home city always stays at 12 o’clock for simplified reading.
Time in the given city is displayed by means of a rotating hour disk with large Arabic numerals and a bright red triangle printed on it at 12 o’clock.
The lonely rectangular-shaped hand that you can see on the photos is here to display minutes.
Another trick is that the Longitude 45 displays not the traditional 24 time zones but only half of that number, which is relevant to one of the three main travelling destinations: Americas, Europe and Asia.
The model AMERICA Traveler, for example, displays zones from GMT -10 to GMT +1 from Honolulu to Paris respectively.
The EUROPA Traveler lets you know official time in the vast area from Mexico City (GMT -5) to Novosibirsk (GMT +6.)
And the ASIA Traveler tells time from the Azores (GMT 0) to Nouema (GMT +11.)
As usual, the watch is delivered in a mid-sized 42 mm case made of their signature 1.4435Ncu Staybrite satin finished steel with polished bezel.
The Longitude 12 Traveler Timepiece is powered by the historic Fontainemelon FHF 96 hand-wound movement. What’s interesting is that there actually are versions of the Caliber FHF 96 with a second time zone indication that do their job with a standard “secondary” hour hand and, at least in this respect, don’t differ much from any other GMT caliber. However, as you can see, this particular version of the mechanism doesn’t need a secondary hand at all replacing it with the aforementioned “time disk”. Although the complication seems to be rudimentary at best, it has its own value as an object of art and I must admit that it gives the watch a very welcome twist among hundreds of other “traveler’s companions” that are currently available on the market.
