Good things stand the test of time—what is true of life applies all the more so to the world of watches. Already in 1994, with the Grand Régulateur, Chronoswiss created a regulator in a stately 44 mm dimension which could be worn as a wristwatch or pocket watch thanks to its convertible case. Launched in 2006 as a wristwatch, the successor has since loyally complemented the collection. A decade later, the time is now ripe to release this Regulator model in a new dimension as well: As the Flying Grand Regulator, the watch is now presented in a new, contemporary look with an innovative, 3D dial.
Like its little brothers, the Flying Grand Regulator is set apart by its intricate dial design featuring several levels: While the lower one is decorated with the characteristic guilloche pattern designed at Chronoswiss´ in-house studio, a second level was designed over it on screw-fastened bases with the scale for the central minute display. The dial is topped off by the funnel-like displays for the hour and second floating above the minute scale.
Chronoswiss’ love of detail and horological finesse is also revealed in the latest addition to the Regulator collection: There is a smaller counterpart under the minute hand that accurately depicts an inverse image of the areas of the minute scale on a central miniature scale. These are hidden from view due to the overlapping of the large scale with the hour funnel. This trick elicits light-hearted joy for the sophisticated design because the minutes can be precisely read. The aesthetically, sophisticatedly designed hand-wound movement is characterized by a second stop: Pulling on the crown triggers a slide that blocks the balance spring. Thus even the second hand can be stopped and precisely set.
