CALIBER RM 004-1: Manual winding movement with hours, minutes, chronograph, split seconds, power reserve, torque indicator, function indicator.
Rm Collection Watches Dimensions: Length 48 mm x 39.00 mm (widest point) x 15.05 mm (thickest area) MAIN FEATURES (MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS) POWER RESERVE 70 hours (numerical indications to the left of the barrel) CHRONOGRAPH (column wheel in titanium) The modern architecture of this movement has allowed for the consistent and rational arrangement of its constituent parts, avoiding unnecessary superimpositions and permitting the best possible use of the functions with technical solutions. For example, research was conducted into the geometrical design of the column wheel that controls the different levers to ensure the perfect, long-term simultaneity of the functions, a feature that is essential for a high performance chronometer. This design was implemented in order to achieve a high degree of continuity of settings and an unfailing repeatability of the various functions. Operation: The user can start or stop the chronograph function via the pusher located on the lower left at 8 o clock. The hands are reset by pressing another pusher located on the upper left at 10 o clock. SPLIT SECONDS MECHANISM with improved function One of the new characteristics developed for the RM 004-1 is the virtually complete elimination of initial jumping in the chronograph seconds hand. A great number of studies led to the design and manufacture of gear wheels and levers in titanium, thus reducing inertia. Moreover, the development of a new generation of split seconds components meant that energy consumption could be lowered by approximately 50 % by reducing friction on the spindle, as well as eliminating the jumps on stopping, thanks in particular to research that focused on the working of the split seconds arms. Operation: simply by pressing the pusher on the right (at 4 o clock), the user can stop the split seconds hand to read an intermediate
