[Brief Comment] The cooperation between Longines and Wittnauer has a history of 120 years. With the support of Longines, Wittnauer provided the Navy with two watches during early aeronautical tests, and it quickly became famous. So that in the early 20th century, almost every pilot wore a Wittnauer watch. This is a pilot watch produced by Longines for Wittnauer, with a very rare sterling silver case. The design of this watch is the same as Longines’ ‘Lin Bai’, and it uses the Weems seconds setting function, which is a more classic one of the classic Longines. However, due to the age, the appearance of this watch has been severely damaged, the case and dial are worn to a certain extent, and the movement needs maintenance. If the appearance is better, this expression will be fine to the upper limit of the valuation.
