Longines caliber L289.2

Based on ETA E57.211 The movement developed exclusively for Longines stands out for its high degree of precision for an analog watch (±5 s/yr) and its ability to reset its hands after an impact or exposure to a magnetic field, using the GPD (Gear Position Detection) system. These attractive features are likely responsible for its status as an exceptional movement, to which a very long battery life and a perpetual calendar must be added. Battery Renata 394
