About this entry
68% of key specs known. Missing: weight, hardening, bracelet links, end links, link attachment, clasp micro-adjust.
The 36mm Flyway with the La Joux-Perret G101 Soigné (time only, 68h; Isotope: tested in 4 positions, averaging ±7 s/day). Every Flyway listing offers the same watch with the Swiss Landeron 24 at £1,200 instead of £1,496; that build is a separate model, flyway-landeron-24. Shared spec table: three-piece 316L steel case with polished, brushed and sandblasted finishes and a Clous de Paris bezel, 36mm, 12.3mm thick and 42mm lug-to-lug (Fratello gives the same), saddle-shaped "hyperbolic paraboloid" AR sapphire crystal (no schema shape fits, so shape is blank), screw-in sapphire exhibition caseback (Isotope; Fratello says it is affixed with screws), mirror-finished push-down crown with the Lacrima logo, 100m, Lacrima hands with Super-LumiNova, and an 18mm quick-release 316L bracelet with a signed butterfly clasp. Each colourway is limited to 100 pieces across both movements. The first Flyways (Cayana Blue, Purple Air, Blink Air, Off-White Air, Terra Maris) were listed in March 2025. On 2026-10-25 the G101 build was in stock in every colourway except Guilloché and Off-White Air. Prices include UK VAT (Fratello: US$1,698 for the G101 Fata Morgana outside the UK). Weight and bracelet link details aren't published.
