The “Grand Régulateur” has been there before at Chronoswiss. In 1994, the brand launched the limited edition “Grand Régulateur” pocket watch, which, with the help of a second case and a bayonet connector, could also be worn on one’s wrist.
Since the hand-wound caliber C.1722 R made by the movement manufacturer Minerva was only available in limited numbers, the previous edition “Grand Régulateur” had to be strictly limited to 300 pieces.
Things are a little different for the “Grand Régulateur” 2006: It should also be linked to the hand-wound tradition, which, for Chronoswiss, began with the long sold-out ancestral Régulateur of 1987.
Since Gerd-Rüdiger Lang represents the clear concept of selling aesthetic watches and not just hot air, there are limitations to the growth using the automatic caliber C. 122.
An increased diameter would fill the corresponding case in addition to the movement with lots of vital gas. Additionally, the aesthetics of the dial would suffer tremendously since the hour- and second-scale would move far into the center.
The case of the “Grand Régulateur” in the typical Chronoswiss style measures 44 millimeters. When one turns the paned back to the front, one discovers the 16 1/2 -lined hand-wound movement C.673 with a diameter of about 36.6 millimeters.
The base movement is ETA 6498-1. In order to be able to and to be entitled to animate the “Grand Régulateur”, the established hand-wound movement has to endure quite a bit. It starts with the move of the hour-wheel from the center towards the “12”, is continued by supplementing a balance-wheel-mechanism as well as by assembling an elegant swan-neck adjustment and is completed by a painstaking finishing.
