There are three styles in the new series, each of which is available in stainless steel and 18K gold. The stainless steel version is limited to 1,888 pieces, while the 18K gold version is limited to 188 pieces, all of which are contained in exquisite wooden gift boxes. Each heartbeat Maufact GMT (CALFC-938) has a new second time zone function and 42-hour power reserve. With a diameter of 30.50 mm, it is decorated with 27 precious stones, and has KIF shock absorption system, Glossay and Nivarox balance balance wheels. The bridge plate of the movement is decorated with Geneva stripes and fish patterns, as well as chamfering, polishing and rhodium plating. Each dial has a second time zone timer, a day/night display at 12 o’clock, a Heart Beat window at 6 o’clock, and black hands. Very practical design, it is easy to adjust the time zone in the crown, and there is no need to add a separate button. Turn the crown clockwise to set two time zones; Turning the crown counterclockwise will only correct the middle pointer.
The history of Constance’s "Heart Beat series" can be traced back to 1994, and its purpose is to become a Constance mechanical watch that is completely different from the battery-powered watches on the market. At that time, the dial on the balance wheel was windowed to show the operation of the mechanical movement in the watch. The balance wheel vibrates 28,800 times per hour and rotates clockwise and counterclockwise on the pendulum needle on the big ruby. The dynamic rotation is controlled by the continuously and repeatedly rolling hairspring, which is clearly visible through the "Heart Beat series". Since 2004, Constance has joined the elite Swiss watch brands, and developed and produced its own movement. Up to now, no other Swiss watch brand, which belongs to luxury goods acceptable to the public, can develop similar movements by itself.
Constance strives to bring forth new ideas in the field of watchmaking. Through independent research and development and manufacture of movement, it shows the brand’s extremely high watchmaking concept, and at the same time reveals the brand’s commitment to innovation and the pursuit of higher technology and the quality of movement production.
