Urban Jürgensen reference 3
Yellow gold N°098
NOS, never worn, box, certificat and booklet
This is a rare opportunity for every high-class collector to own a legendary Urban Jürgensen reference 3. It comes in NOS condition, never been worn with box, certificat and booklet. The fact that this example never has spent time on a wrist is a unique chance for every connaisseur of independent watchmaking.
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 (image of the mechanism in the gallery), 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 (photo of the perpetual calendar mechanism in the gallery). 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.
This timepiece is certainly a connoisseur’s choice and a great addition to every high-class watch collection.
