Glycine Watch F104 GL0126. Since 1953, the history and development of Glycine have always been connected with the evolution of aircraft and aviation. Many Glycine watches carry the hallmark of this affinity, such as the F 104. Conceived in the fashion of a cockpit instrument, this extraordinary model impresses by its pure functionality. The watch features a stainless steel case that houses a manual wound pocket watch movement. A domed exhibition back attached securely by six screws allows for a full view of the movement. Despite its extraordinary size, the case is ergonomically designed and conforms to any wrist by use of articulated lugs. A pyramid-shaped double o-ring crown lends an antique look and touch long missing from todays fine timepieces.
