Universal Genève Calibre 125

Calibre 125 is a manually wound chronograph movement manufactured by Universal Genève. Based on the Valjoux 23, it measures 13 ligne (29.5mm) in diameter and operates at 18,000 vph. The movement was produced exclusively for Uni-Compax versions of Universal Genève watches and is identified in some references as "125 (84)". As a sourced caliber rather than an in-house development, it belongs to the Universal Genève tradition of integrating established ebauche movements into their chronograph family. Production has been discontinued.
