Vacheron Constantin 1127

Caliber 1127 is an automatic chronograph movement manufactured by Vacheron Constantin, introduced in 2017 and still in production. It belongs to the brand's in-house 11xx caliber family and incorporates additional complications beyond the chronograph function. The movement reflects Vacheron Constantin's continued development of proprietary chronograph calibers using base mechanisms introduced decades earlier. Notable Vacheron Constantin watches featuring this caliber include references within the Traditionnelle and Overseas collections.
