The Longines SPIRIT (ref. L3.410.4.63.6) is an automatic watch, with a 37mm stainless steel case, 11.7mm thick, powered by the L888.4 movement and a 72-hour power reserve. Water resistance is rated to 100m, under a sapphire crystal, with hours, minutes, seconds and date complications. Manufacturer MSRP is $2,850. The dial color is ivory.
Owners and reviewers widely praise the Longines Spirit for its exceptional finishing, refined vintage-inspired design, and strong value proposition, with many finding the 37mm and 40mm variants to be a "sweet-spot" size for wearability. The champagne dial with applied indices on the 37mm model is noted for its depth and legibility, while the L688.4 movement in the Chronograph is appreciated for its COSC certification and silicon balance spring. Some owners report accuracy within COSC specifications, and the 72-hour power reserve is a frequently cited positive. However, some community members find the bracelet finishing and end links less refined than competitors, and one owner noted the presence of three different fonts on the dial numbers of the 37mm. The 37mm model's non-screw-down crown despite 100m water resistance and the lume strength are also flagged as potential drawbacks by some.
