Agenhor caliber AGH-6801
AGH-6801 by Agenhor incorporates:
a. AgenEse® gear for unhesitant movement of the eccentric second hand
b. AgenPit® regulator for easing adjustments to the hairspring without using collets nor a regulation lever
A small window in the baseplate displays the AgenEse® second wheel with slip-free timekeeping accuracy. The spring-like elastic teeth prevent gear slippage, that is particularly advantageous for watches with eccentric seconds, as they are subject to hesitancy caused by small interferences within the gear train. As the seconds hand of Étude No. 1 is set in a sub-dial at 8:30, the addition of the AgenEse® gear provides seamless transmission of power from the mainspring to the eccentric second hand befitting a movement of this calibre. This innovation is so important that Jean-Marc Wiederrecht considers it the most significant of his distinguished career. The AGH-6801 also benefits from the addition of the AgenPit®, a balance regulation mechanism that allows for fine adjustments to the hairspring by rotating an adjustment organ to adjust the effective length of the hairspring. In addition, the AgenPit® can be moved in its entirety using two screws, which allows the beat of the balance to be tuned. There is no need for a regulation lever or collet pins to achieve optimal accuracy. The movement beats like a metronome at an unhurried 21,600 semi-oscillations per hour.
