Longines Spirit 37mm Chronometer
COSC-certified pilot watch at an incredible value.
Our take on the Longines Spirit 37mm Chronometer
Longines' Spirit line draws on the brand's genuine aviation history rather than a borrowed aesthetic, and the 37mm size answered the main criticism of the original 40mm and 42mm cases. Every Spirit is chronometer-certified, which is unusual at this price.

Where and how to buy
Authorized dealers discount Longines more readily than most Swiss brands — expect meaningful room on list price. The bracelet is worth specifying at purchase; buying it separately later costs more.
