The 1950s were foremost marked by the Post World War II Boom. New consumer goods such as cars, televisions and refrigerators became available to more people than ever before. The booming prosperity originated new music genres such as Rock ’n Roll, and in industrial design bright primary and secondary colours became fashionable. In Europe the Mid-20th century saw the birth of the unification process and in Great Britain, Elizabeth II ascended the throne and became Queen of the United Kingdom and the Commonwealth.


In those times the mechanical wristwatch was a delicate and precious object that asked for special and precocious care. It is in that context that Vacheron Constantin in 1951 created the reference 4737, which Italian collectors nicknamed ‘Cioccolatone’, as its shape is reminiscent of a square of Swiss chocolate. Its design was radical and broke with the aesthetic codes of the time. Concurrently, rectangular and square (through its dial opening), the case additionally is curved to better fit on the wrist. Above all, its impressive size (36mm width and 43mm length) made it stand out from all other watches on the market.


Soon after the “time only” model, the spectacular complete calendar with the display of the moon phases was introduced. Excitedly original and daring, reference 4764 was to become one of Vacheron Constantin’s most sought-after models by collectors, equally for its unique aesthetic and rareness. To the best of our knowledge, in total less than 50 pieces were finally produced until 1957.


The ‘Cioccolatone’ hence became a success with connoisseurs and collectors. Nevertheless, its production remained very limited. In fact, all versions combined less than 650 pieces left the Vacheron Constantin workshops between 1951 and 1969. Six versions of the ‘Cioccolatone’ will see the light of day:


  • Reference 4737, 6440 and 6440Q (automatic winding mechanism, calibres 477 – 1019 – 1071 – 1072)
  • Reference 4764 with complete astronomical calendar (manual winding mechanism)
  • Reference 4821 with small seconds (manual winding mechanism)
  • Reference 4822 with centre seconds (manual winding mechanism)


Later, the celebrated ‘Cioccolatone’ was several times revisited in different variations and sizes:


  • Reference 39044, 31100 and 11100 in 1990
  • Reference 42100 and 121000 as part of the ‘Les Historiques Collection’ in 1998
  • Reference 47300 in 2003 
  • Reference 86300 integrated in the ‘Historical Collection’ in 2013


The present platinum version of reference 4764 is to date the one and only piece referenced in the archives of Vacheron Constantin. It was sold in Athens, Greece in 1957 and it is fresh to the market, hence the first time in auction. This unique piece impresses by its sheer presence and strong proportions. It is furthermore offered with its original unrestored dial and a Vacheron Constantin Certificate of Authenticity. Without a doubt, this might be the only occasion for passionate Collectors to obtain such a historically significant timepiece as a second opportunity might not appear so quickly again... if ever. 


We would like to thank the Vacheron Constantin Heritage Department for their support with the research on this piece.
