The pictures posted here are of the A. Schild caliber AS 1475 found in a vintage Buren alarm watch. It is signed J.P. Pingouin. There are two crowns. The crown at 2:00 winds the alarm. The crown at 4:00 winds the movement and sets the time. You also set the alarm hand with the crown at 4:00 by turning it counter-clockwise. Then, to activate the alarm function, you pull the 2:00 crown out…pushing in to disable the alarm.

From PeterCDE:

The AS 1475 debuted in around 1954 and was made until around 1970. The first alarm movement by the well known AS factory which delivered movements to many many makers those days. The AS 1475 is a 11 lignes movement featuring a glucydur compensating balance, flat hair spring, 18.000 A/h beat rate, two barrels (one for the alarm, one for the watch), indirect centre second and 17 jewels. Reportedly a total of 780.000 movements was made.

There is also a similar caliber AS 1568 with the only difference being a date feature.

The AS 1568 is basically the same as AS 1475, but came out in 1956 and does have a date. The reported production total is about 149.000 movements.

Additionally, you may find two more calibers which beat at a higher 21,600 vph: the AS 1930 and AS 1931 with a date. Both manufactured into the mid-seventies.

According to The Watch Spot:

The original AS cal. 1475, easily qualifies as the world’s most widely used alarm calibre. Production started in 1954 and in its 16 year production cycle, more than 750,000 were made, some of which were re-branded for other watch manufacturers; Tissot, Benrus, Bulova and Girard Perregaux to name but a few… The AS 1475 was used as the basis for alarm calibres developed by other manufacturers too, such as Citizen and Poljot/Sekonda. The Poljot cal. 2612.1 found in the majority of Russian alarm watches is an almost identical copy of the AS 1475.

Excellent post! What really has peaked my curiousity, though, is how can one tell the difference between the AS1475 and AS1930 if there are no markings? The movement in the photo does not actually say AS1475, so could it be an AS 1930?

The title is a AS 1475 why would they title it AS 1475 if it’s a AS 1930?

The 1930 and 1931 have a different regulator with micrometric regulation.

The 1475 is usually marked by the balance wheel, under the alarm hammer. There would be the “AS” shield, and “1475” stamped into the plate. As the photo does not have enough detail/resolution in that area, it will be hard to determine exactly what this example is.

It clearly says “The pictures posted here are of the A. Schild caliber AS 1475” doesn’t it?

Excellent and enlightening your post.
I got a Mondaine 269 with this movement, and I was looking for reference, because on the net I did not find anything about the model.
Thank you.

I just came into the possession of an Elgin pocket watch with “978” stamped on the movement. I could only find one reference to it and said it was also known as an AS 1475 which led me here. I have read Elgin imported Swiss movements for some watches in their final years of production (late 1950’s through mid-60’s). My watch shows obvious signs of wear but it still runs strong and the alarm still… Read more »

This movement also powers a SCUBA (brand) Alarm by Bellmont Watch Company France.
