Description
For the RM04 Richard wanted something new. Rather than the old method of using a column wheel that was stopped and started using a system of levers that would interact with the column wheel, Richard went after an innovation in the way the rattrapante worked.
The important part to any chronograph, if you wish to measure time accurately, is the stop/start part. The more instantaneous the stop and start the more precisely you measure the time elapsed.
Richard’s main concern was inertia. Specifically: The jumping of the rattrapante when starting and stopping, due to the mass of the hand and gears, should be eliminated as far as possible. To do this a ‘pincer’ made of titanium, in which both arms work simultaneously, engaged from one point, in order to ‘grab’ the split seconds gear in a single swift movement.
In a standard rattrapante, this is done by two separately activated levers, with the corresponding problem of having to adjust these accurately, such that they reach the gear at the same moment.
This watch features a Manual winding movement with hours, minutes, seconds, split-seconds chronograph, 30-minute totaliser, power-reserve, torque and function indicators.
