At the heart of the spirit collection stands the longines spirit pilot flyback, a testament to the brand’s pioneering role in flyback chronograph development. This sophisticated timepiece celebrates a technology longines invented in the early 1930s, when the brand produced the first flyback chronograph watches before filing its groundbreaking patent in 1935. The new spirit pilot flyback presents reimagined dimensions within a refined 39. 5 mm stainless steel case, measuring just 13. 4 mm thick for a sleeker, more comfortable profile. The bidirectional rotating bezel benefits from an improved rotating system and introduces a countdown timer for the first time, while the box shaped sapphire crystal and matt black dial create the distinctive aesthetic of vintage aviation instruments. Gold coloured hands and applied numerals treated with super lumi nova® ensure exceptional visibility, while honouring the functional requirements that made pilot watches essential cockpit tools.
