The Longines Spirit Pilot Flyback represents a more substantial redesign of the two, dramatically reducing in size from 42mm to a significantly more wearable 39.5mm steel case, with a 13.4mm thickness. A streamlined bidirectional 120-click ceramic bezel, this time with more niche countdown bezel markings, surrounds the matte black dial with gilt accents that match the time-only Spirit Pilot. 

Most importantly, the stars are also gone, replaced by the “Chronometer Officially Certified” text. There is one design compromise, however, given the smaller case size, the 2, 4, 8, and 10 numerals are partially cut off to accommodate the spacing of the subdials of manual-wound Calibre L792.4. This ETA Longines-exclusive caliber is officially COSC-certified and features a silicon balance spring, a 68-hour power reserve, and a blued column wheel visible through the exhibition caseback. On the steel bracelet, also with tool-less microadjustment, the Spirit Pilot Flyback is priced at $5,500.
