Swiss automatic from Landeron Swiss Movements (the revived Landeron name), built as a replacement for the ETA 2824-2 on the same architecture (Grail Watch Reference; Monochrome calls it "based on the architecture of the ETA 2824-2"). Base version: central seconds, date at 3, 25 jewels, 28,800 A/h, 40h power reserve, 11½ lignes (Grail Watch); hacking and hand winding per Fratello's spec list for the Isotope Flyway. Grail Watch lists a family of options on the same base (small seconds, power reserve, big date, moon phase, 24-hour and GMT versions with 25-27 jewels, and the day-date L36). No factory spec sheet or accuracy range was found; the ±12 s/day quoted by brands using it (Isotope) is recorded on their models. Height and exact diameter are not published. Grail Watch reports Landeron telling it that no components come from Chinese factories.
