Reference 1741

Introducing the Jürgensen 1745 Collection, Urban Jürgensen presents Reference 1741 in Platinum with Perpetual calendar, leap year indicator, moon phase and central seconds. Reference 1741 is equipped with a Grenage dial for the first time in more than 100 years and reintroduces the almost forgotten craft which is hardly used or even known today.

It is handcrafted, delicate and time-consuming, but the final result justifies the difficulties of creating the Grenage Dial. The Reference 1741 dial is hand made using Grenage dial making and fitted with the Urban Jürgensen white gold Arabic appliques. The moon disk takes more than 20 different operations to create, and the result is a unique tiny wonder of classic workmanship which is rarely found in timepieces nowadays.

The Ref 1741 caliber is based on the Urban Jürgensen P4 In-house movement, enhanced with the QP functionality that has been augmented by introducing the leap year indication. The Ref 1741 is executed in a 41mm case in traditional Urban Jürgensen teardrop lug case. The elegant profile of convex and concave curves of the case consists of 3 main pieces; the middle case with individually soldered teardrop lugs, the top bezel houses the domed sapphire crystal, and the screw back with a flat sapphire crystal.
