On March 3, 1967 Henry L. Blum of Montres Yema S.A. filed a patent for a ‘Watch for Yachting and Underwater use’.

This resulted in the introduction of the Yema Yachtingraf in 1966. All together 6 different models (7 if you count type 6 in standard or jumbo case as two) of the Yachtingraf were sold between 1966 and 1970. Type 1 (Valjoux 92), type 2 ( Valjoux 7733 or 7734) and type 3 (Valjoux 7734 with date) have a subdial counting the seconds at 9 o’clock, and an oversized 30 minutes subdial at 3 o’clock, divided into 6 differently coloured segments representing 5 minutes each.
