V.I.P. Memosail Regatta Swiss Made mechanical chronograph watch from the 1970s.
The watch is based on the caliber Valjoux 7737 (derived from the caliber 7733), patented by Valjoux SA in 1972 as a “Pièce d’horlogerie à mécanisme de chronographe”, and was first produced in 1972 under the trademark Memosail, registered by Ebauches Electroniques SA. In the mid 1970s the Memosail Regatta watch is sold as “V.I.P Memosail” (trademark name registered by the same Ebauches Electroniques SA). The additional word V.I.P appears both on the dial and on the case back.
The watch diameter is ca. 43.5 mm (without the crown) and it’s one of the late models produced with a Valjoux 7737 movement, therefore it has a full stainless steel case (unlike the first models which were chrome plated brass).
The Memosail has two pushers for the chronograph / countdown function. One pusher at 2 o’clock for start/stop, and one pusher at 4 o’clock for reset. Under the dial is a plastic indicator disk divided in 15 segments for a total of 15 minutes, of which 5 segments are shown through a large opening in the dial from 12 to 4 o’clock to follow the countdown. After a reset it shows 10-9-8-7-6 in black figures on a yellow background. When the chronograph is activated, the countdown starts and the orange sweep hand is set in motion counting the seconds backwards from 60 to zero. After 30 seconds the indicator disk moves half a minute, and again after 60 seconds, now showing 9-8-7-6-5, and so on until it reads START in green capitals on a white base.
The watch band is a genuine and very rare BESTFIT TROPIC rubber strap, which was the ideal band for a water sport watch in that time. The actual value of the strap only varies from $100 to $250 nowadays.
