It can be rather difficult to find a 1970s chronograph larger than 40mm – small by today’s standards – yet this full serviced 1970s Memosail Olympic regatta chronograph here is precisely that, measuring in at a rather large 48mm across.


Dating from the early 1970s, this colorful chronograph features the famously robust, manually wound Valjoux 7737 (a modified 7733).  The Valjoux manual movement, first produced to acclaim in 1969, was used until 1978; the 773x movement was used by Breitling, Tudor, and Heuer during the 1960s and 70s.


And this one has an Olympic heritage!  Hedging their bets, the Memosail chronograph adorned the wrists of American, Canadian, Swiss, British, Belgian, French, and German teams at the 1972 Summer Olympic Games held that year in Kiel, Germany.


Regatta yacht racing requires a countdown period before the start of a race to help keep the boats as fairly placed as possible. Before the start of a sailboat race, there are two guns, the first gun signals that the race will start in either five or 10 minutes (depending on the type of race sailed).


At the five minute mark, a gun is sounded and the sailors start their countdown functions and maneuver their sailboats as close to the start line as possible. Once the end of the five minute blue period is reached, the race has begun.


This Memosail comes on a nylon strap, and with another nylon strap, rugged travel case, and springbar tool.
