DeWitt Academia Tourbillon Force Constante a Chaine Watch

The DeWitt Academia Tourbillon Force Constante a Chaine watch is a brilliant development of the DeWitt manufacture's tourbillon movement with a constant force device.  This new model utilizes the manual winding DW8050 caliber, which employs a barrel-spring driven chain--visible from the dial--to activate a sliding power reserve indicator.  The sliding power reserve indicator moves on a worm screw, and shows the state of the spring barrel at its various stages of tension.  

The DeWitt Academia Tourbillon Force Constante a Chaine watch is presented in a 43mm platinum case, whose intricate "Imperial Columns" design emphasizes exceptional attention to finishing.  Equally intricate is the silver and black dial, with its openings for the tourbillon cage, constant force device, and the power reserve complication with its miniature driving chain.  Hours and minutes are shown via white gold hands which are hollowed in the center.  The crystal is in sapphire, and the alligator leather strap features a deployant clasp in platinum engraved with the DeWitt signature.  

Power reserve of the manual-winding movement in the DeWitt Academia Tourbillon Force Constante a Chaine watch is 72 hours.  The flying tourbillon cage completes a full revolution every sixty seconds, bearing a glucydur balance with a flat hairspring that oscillates 21,600 times per hour.
