Reference 2, Platinum

A Reference 2, one of 50 examples made in platinum (172 examples across all metals). Urban Jürgensen's first complicated calendar, the Reference 2 established several principles that would define the Pratt-Baumberger years. Its stepped-bezel, two-body 38mm case had a more contemporary soldered-teardrop lug profile, the Observatoire handset was introduced, and thoroughly reworked Frédéric Piguet ébauches were introduced. Each dial took Pratt roughly a week, manually turned with a level of skill few have rivaled. The Reference 2 defined the revival of Urban Jürgensen and set an archetype for some of the most beautiful wristwatches of the 1990s—still influencing the brand's direction under the Rosenfields with Voutilainen today.
