Calibre 5100 is a manufacture automatic movement from Vacheron Constantin first produced in 2016.
Vacheron Constantin long relied on ebauche movements from Jaeger-LeCoultre, F. Piguet, and Audemars Piguet, but in 2016 they unveiled a family of in-house automatic movements to be used across their product line. Cal. 5100 is the company's basic time and date movement, with central rotor automatic winding and modern 28,800 A/h frequency. The movement is quite large, measuring 30.60 mm (13 1/4 ligne) in diameter and 4.70 mm thick. It is also extravagantly jeweled, with 37 jewels specified. Vacheron Constantin is proud to have a Geneva Hallmark on all these movements.
This movement replaced the Jaeger-LeCoultre-derived VC 1126 movement in mainstream time-and-date watches from Vacheron Constantin such as the "Large Model" Overseas, though Cal. 5100 is quite a bit larger and thicker than that movement.
The similar Cal. 5100/1 differs mainly in using a tungsten rotor rather than the gold one used in the basic Cal. 5100. This is used in the Vacheron Constantin Quai de L'ile.
Cal. 5110 DT
Cal 5110 DT adds a GMT module with an adjustable hour hand and day/night indicator. This adds thickness to the movement, bringing it to 6.00 mm, and components, now at 234. The movement remains at 37 jewels and 60 hours power reserve. Cal. 5100 DT was introduced in 2017's Overseas Dual Time Ref. 7900.
