In his quest for mechanical, everyday timepieces, Guy Ellia has added a new string to his bow with a new complication: universal time.
Housed in a round 50mm diameter case in 18 carat gold with black, grey or red micro-bubbles, the automatic movement has a reserve of 72 hours and meets the challenge of displaying simultaneously local time and a second time zone for 24 cities with a day / night indicator as well as a large date.
Guy Ellia’s “Jumbo Heure Universelle” 2009 makes its mark as a complicated timepiece, an ambassador for high watch making as well as being useful on an everyday basis, particularly for globe-trotters who love clever watch movements.
This is great watch-making art staged in the heart of a dial whose open centre gives a view onto part of the skeleton movement. At 5 and 6 o’clock there are also two discs displaying the big date for reading in a line.
The two central hands for hours and minutes turn on the same axis as the hand intended for the second time zone, the blue colour of which matches the turning cities disc.
The disc, activated by the button located at 2 o’clock turns under a blue sapphire glass and displays the city corresponding to the second time zone, chosen in a window located at 12h.
Water-resistant to 3 bars, the Jumbo Heure Universelle has an alligator strap with an 18 carat gold butterfly clasp.
Despite the complexity of its dial, this is a watch that is simple both to use and to read.
