Overview
The Longines Spirit 40 (ref. L3.810.4.53.6) is a 40 mm stainless steel pilot's watch introduced in 2020 as part of the revived Spirit collection. Its matte black dial carries luminous Arabic numerals for clear legibility in low-light conditions, and the movement holds COSC chronometer certification. The watch draws on Longines' long association with aviation timekeeping, translating that heritage into a contemporary, wearable package.
History
Longines launched the Spirit collection in 2020, revisiting the brand's storied role as a supplier of precision instruments to aviators and navigators throughout the twentieth century. The Spirit 40 sits at the core of the line, offering a case diameter that balances vintage pilot proportions with modern wrist presence. Powering the reference is the in-house Cal. L888.4, a high-frequency silicon-escapement movement that earned COSC chronometer status, reflecting Longines' ongoing commitment to certified accuracy.
