Recently aquired this movement for a project:
This is what I know, correct me if I am wrong:
After Schild Freres, the movements were signed U. Schild ( Urs Schild ) the son of Anton Schild.And then, when Urs's son Max and Adolph Schild couldn't work together anymore, Urs went on by his own company which became Eterna in 1906 and its ebauche division ETA, and Adolph Schild continued making ebauches and all the calibers we know now, A.Schild.
ETA and A.Schild formed the ASUAG in 1930,the same year when Omega, Tissot and Lemania formed SSIH, the basics of recent Swatch Group after a long journey.
The question is:
Since this movement is signed U.Schild which became Eterna in 1906 ( I saw the alarm watch from Eterna produced in 1908, PW, the movement was signed Eterna ) can we assume this is from pre 1906? Or was Eterna still using some ebauches signed U.Schild from their inventory? The watch dial looks a military dial with a red 12, which we see in WW I era trench watches. Do you think this dial and movement belong originally together and were made as a wrist watch in the first years of the 19hundreds? Or is this a ladies pendant watch alike design? The diameter of the movement is 23 mm, and I couldn't identify the movement.
Thanks for any input
