This thinness is the result of perfect technical mastery, especially since this calibre incorporates a tourbillon regulator mechanism designed to compensate for the effects of gravity on the isochronism of the balance-spring. ⚡To clearly understand how it operates, this regulator has been set to a frequency of 18,000 vibrations per hour (2.5 Hz). This relatively slow tempo often found in historical pocket watches provides an opportunity to appreciate at leisure the tourbillon’s mechanical ballet. 🔎 The show that can be admired through the sapphire crystal caseback is enhanced by the movement’s structure incorporating a peripheral rotor. The latter reduces the thickness of the calibre as well as ensuring a comfortable 80-hour power reserve. #VacheronConstantin #OneOfNotMany #vacheron #thehourlounge #watches #watch #watchesofinstagram #horology #watchoftheday #instawatch」11月25日 1時07分
