Derby - Swissonic Jump-Minute Circa 1975

Here is a Derby Swissonic Jump Minute, dating from around 1960.

Its 41 mm chromed steel case houses an unusual dial with three distinct apertures. One window displays the hours, another the jumping minutes, while a moving line represents the passing seconds, offering a unique and technical way of reading time.

This watch stands out for its jumping hour and jumping minute complications, characteristic of innovative timepieces from that era.

It is fitted with its original Derby signed bracelet, suitable for a wrist up to approximately 19 cm.

The watch comes with our 6-month warranty on the movement.
