Rapport London watch winder
An automatic watch has a mechanism that requires regular motion to keep the inner spring constantly charged. This motion is usually provided as it is worn. Once removed from the wrist the stored energy will only run for 24-72 hours, depending upon the model, then the watch will need to be manually rewound and reset.
Many automatic watches have additional features, or 'complications' - date, moon phase, world time, annual calendars, etc. so the task of rewinding and recalibrating a watch if it runs down is best avoided.
Furthermore, watches of such caliber are precision instruments and like all thoroughbreds they actually benefit from exercise. If left unwound for long periods, internal lubrication can be lost from critical areas which will eventually lead to excessive wear on components and subsequent lack of accuracy.
All Rapport Watch Winders have features designed to mimic the action of a watch being worn. The watch is held at a precise angle while being rotated and the winder can be set to run intermittently so that the watch is not permanently fully wound. It is not possible to over-wind a mechanical watch due to a clutch in the main-spring. If such a watch is then taken off by the owner, the spring can relax. Timepieces which run constantly in watch winders work on a longterm basis within the clutch-slip-range. In order to avoid unnecessary load of the clutch, Rapport Watch Winders simulates normal use by starting and stopping its winding program at specific intervals. The Rapport Satin Double Watch Winder has a solid wood case. The natural walnut finish of the winder is enhanced by the hard varnish that gives it a smooth, tactile feel. The interior is lined with soft, luxurious velvet.
Rapport is commited to technical perfection. Modern standards, functionality and reliability are the main focus. All Rapport Watch Winder runs silently making practically no noise; thus an extremely long, disturbance and maintenance-free life is guaranteed. This Rapport Watch Winder has two modes of operation, timed and constant. Timed mode is the setting to be used under normal use, will rotate 1130 turns per day. Constant mode is to be used for display or for quickly winding your watch, will rotate 3690 turns per day. Both modes are programmed to run clockwide and counter-clockwise during specific intervals so to not keep the watch fully wound at all times but maintaining the power reserve so the watch does not stop.
