The dials on the Flying Regulator Open Gear Anniversary Editions are engine-turned by hand to create a complex guilloché pattern, while they also serve as module boards for exposed train wheel bridges. The multi-dimensional finished dials with raised sub-dials are partially skeletonized and much more elaborate than a classic piece like the Regulator Classic Date. A regulator setup has each hand separated in its own register, which helped watchmakers centuries ago set the time on new watches from master regulator clocks. 🇨🇭 ♢ #chronoswiss #regulateyourtime
