Dear watch aficionado.
The "reference 3 model" used by Peter Baumberger and Derek Pratt for the official Urban Jürgensen catalogue is this N°015 in yellow gold, which adds that little extra to this example and sets it apart from other reference 3 examples. The more, this example was never worn, comes with its box, outer packaging, original certificate, booklet, original catalogue and original price list from 2003.
In the 1990s, when the
reference 3 was presented, Urban Jürgensen was guided by Peter Baumberger and together with Derek Pratt they developed their
collections. Derek Pratt was as well the one who developed the up/down
mechanism on the reference 3,
which took almost 2 years of research, different technical drawings and three
dozens of additional parts to finally fit into the ultra thin (2.4mm)
Frédérique Piguet base movement. The more, the whole modification for the
perpetual calendar indication was as well developed and produced in-house at
the atelier of Urban Jürgensen!
To finish the guilloché
dial, it takes more than 700 operations and 2 days of work. The moon display
requires over 20 operations to produce the blued steel background with inserted
gold moon discs and stars that are punched in one by one. The effort required
to produce the elegantly curved springs and levers of the perpetual calendar
mechanism is partially unlimited. Each steel surface is carefully grained and
the edges angled and polished to perfection. The tear drop lugs are individually forged and
then soldered by hand to the case.
The level of finissage on the Urban Jürgensen reference 3 timepieces is at the very highest standards of watchmaking.
