Fully documented service and performance & timing report from former President & Watchmaking Instructor of the American Watchmakers Clockmakers Institute (AWCI), Manuel Yazijian. Quite possibly the best performing example anywhere!

Extra New Old Stock Bezel (watch will be delivered with both bezels, and buyer's choice of which one fitted to the watch). 


An all new Autavia 2446c GMT launched in 1968/69 in a 40mm compression case housing a manual wind Valjoux 724 movement. Two different cases were used with subtle differences including the fit diameter of the bezel. In general first cases had engraved back, plain pushers and plain steel hands. Second cases had plain backs, fluted pushers and hour and minute hands with red insert.
