échappement Richard libre excentrique à ressort et irrenversable, circa 1860
My detent chronometer escapement is based on the above, by the great Louis Richard.
In my rendition of the open source escapement I’ve managed to make all parts from grade 5 titanium and expanded its reach to the balance extraordinaire. This includes the thinnest titanium spring in watchmaking that resides on the extended reach pallet arm used for impulse, shock resistance, and locking. The entire escapement is basically, weightless.
Some highlights are a one piece solid titanium escape wheel, titanium extended reach single impulse pallet arm, titanium balance staff mounted impulse roller, and titanium small balance staff shock resistance safety roller. The movement plates consist of two full size mainplates machined in house from solid German Silver bar stock. Steel flatwork and individual pinned bridges and cocks lie, thereafter.
The focal point of my timepiece is a captivating balance wheel, extraordinaire. It is 18.4mm and reminiscent of high grade vintage American pocket watch perched placement. Simply magnificent and mesmerizing to watch in motion, in conjunction with the single impulse escapement. All in full view.
Longevity of parts manufacture
The escape wheel will more than likely never wear out, chip a tooth, or show any wear, ever. Same for the extended reach pallet arm and its shock spring. The escapement needs no oil on the pallet surfaces at all to execute its precision no draw, no loss, chronometer actions. No oil means no sticky pallet jewel faces to hinder time keeping precision, as in other types of production escapements. The single impulse escapement is too complicated, utilizing too many parts, to produce for mass produced watches.
Three years of full time development to execute perfection of this full titanium chronometer escapement and balance extraordinaire system.
