'Highlife Hearbeat', circa 2004; three unique prototype stainless steel wristwatches with visible escapements
The 'Heart Beat Manufacture' calibre was developed by Frédérique Constant together with a team of 8 specialists from the École d'Horlogerie de Genève", "École d'Ingénieurs de Genève" and the "Horloge Vakschool Zadkine" in Amsterdam. A team of 14 specialists were carefully selected for the production of the calibre.
A press preview of the new movement was hosted in Geneva in February 2004, prior to the official launch at the Basel World Watch and Jewellery Fair in April. These three wristwatches are working prototypes made for this presentation.
