Meet Longines Spirit (ref. L3.721.4.53.6), an elegant watch engineered for daily versatility and long-term reliability.

First released in 2025. Designed for real-world wear, the watch transitions smoothly from tailored looks to casual settings. Manufacturing tolerances and surface treatment highlight consistent quality control. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
