Start year is a guess based on no movement stamp, an early style of movement and no serial number.

17J version. Very different movement engraving.

Bestfit shows no listing for this, but is probably stamped under the dial. If we know the manufacturer of the ebauche, we might be able to get a better idea of it's production range. If there is no maker's stamp, we might still be able to identify by the keyless works.

Strange. They look alike except for the different type of jewel for the escape wheel. The position of the 6LA just below the signature is interesting too. Lets see the fingerprint and as Rev says, the ebauche if available.
