40h power reserve28,800 vph (4 Hz)
Cal. C125 is an automatic GMT movement built on the Soprod A10-2 base. It measures 25.0 mm in diameter, stands 5.67 mm thick, and beats at 28,800 vph with a 40-hour power reserve. The movement's distinctive feature is its independently adjustable 24-hour hand for local time, which differs from conventional GMT constructions where the 12-hour hand typically serves that function. Produced by Soprod, it remains in production.
