About this entry

67% of key specs known. Missing: weight, hardening, crown, lume, bracelet offered.

Lebois & Co's Heritage Small Seconds case family, references 641.xxx: every reference shares the 37.8mm 316L case and the COSC-certified automatic LC-350, which Monochrome identifies as a Sellita SW360-1 (31 jewels, 56h, 28,800 vph, all matching the brand); the dials sit on the same case, so the dial families are variants. The SW360-1's date is not shown (hours, minutes, small seconds). Regulation is the COSC standard (-4/+6 s/day). Dimensions: brand spec table gives 10.5mm with the double-domed sapphire, 8mm without; Fratello's Atelier hands-on says 8.5mm without crystal. Lug-to-lug is 45.5mm per the brand and Fratello; Monochrome gives 45.2mm. The spec table says "screwed down" caseback, and the collection page and reviews confirm a sapphire display back. Monochrome describes a fluted crown; whether it screws down, lume and weight are not stated. Launched in October 2025 as a 100-piece Founder's Launch (blue Baton, silver Script, black Numeral) at EUR 2,200 (Fratello), with a Fixoflex stretch bracelet and a sweater included; not a limited edition. On 2026-10-31 the three standard references take reservations for the 2027 production (delivery expected early summer 2027, Fixoflex bracelet included with each pre-order), hence status pre-order. The Atelier references (2026, dials by GT Cadrans) are sold in production runs and are not numbered limited editions: the first 14-day ordering window closed on 10 August 2026 and the store takes registrations for the next run; each comes with an "Atelier Discovery Set".
