It is surprising how the Urban Jürgensen perpetual calendar Reference 3 offers a swept back sense of exhilaration. Everything about the present lot speaks of craftsmanship, sophistication and tasteful restraint.

A student of Breguet, Houriet and Arnold, Urban Jürgensen was considered as one of the greatest watchmakers of the 19th century and his style can be found in the watches bearing his name today.

A cavalcade of subtle yet important details add up to make the present timepiece a must have for the savvy collector. The hand guilloché dial requires up to 700 different operations and 2 full days to complete, the tear drop lugs have been individually forged, heat treated, hand polished and individually soldered onto the watch case in a way which makes the soldering line invisible to the naked eye. The moon disc is also made by hand, it is crafted from mirror polished blued steel, in which the stars are manually inlaid in gold and two solid 18 karat gold, mirror polished moons are fitted.

The movement powering this masterpiece is a superbly finished extra slim automatic caliber with a 21k yellow gold guilloche rotor.

The present Reference 3 also features a power reserve indicator stylishly placed beneath the moonphase display.

The present lot offers immense value to the connoisseur with its enticing looks, artistry, perfectly legible calendar functions and ultimate rarity.
