The tourbillon is one of watchmaking’s most fascinating achievements. Effectively, it involves the balance rotating around its axis in a cage. This not only provides a visual spectacle on the dial: the constant rotation also reduces the influence of gravity on the oscillating system and increases the watch’s accuracy.
The Portugieser Tourbillon Rétrograde Chronograph (Ref. 3940) combines a flying minute tourbillon at 6 o’clock with a retrograde date display at 9 o’clock and a flyback chronograph. The model is available in two versions, both limited to 50 watches. One is housed in an 18-carat Armor Gold® case with a blue dial featuring the maritime- inspired design cues of the Boutique Editions. Thanks to its improved microstructure, this innovative new material has considerably higher hardness values than traditional 5N gold alloys. A second version is available in platinum.
