Comments about the data
gold lever, -escape wheel (only for Mido)
early bumper automatic of AS, redesign of the Harwood automatic
The calibre designation on the dial plane comes from the 8.75''' manual wind calibre AS 612, used as base for this movement.
The signature AS 1049 is probably always missing;
commonly known is only the AS 1049A, differing from this one by a common train bridge.
Example, year: signature; shock device
1935: 5251, Mido, Switzerland, 17 Jewels, 3 Adjusted - AS 612, Brevet+Dem.; Incabloc old shape
