AS 324

Description

The 10 1/2 ligne windup movement AS 324, made in the 1920s was part of the 302 caliber series, which came in about two dozen different designs, all of which differed only in the shape of the bridges and in details like the setting lever.

With 15 jewels, which were also neatly set, this movement belonged among the better lever movements that were available at the time.

The gear train also pleases with its well made execution. Its design is classic, with a directly driven, central minute wheel, third wheel, fourth wheel at 6 o’clock and steel escape wheel.

The AS 324 uses a monometallic, two-leg screw balance used, which of course is not yet shock-proof.

In order to give her an even higher-quality impression, the balance wheel has got two halfway cluouts, so that one can to think at a first glance that you are looking at a bimetallic balance wheel.

It beats with 18000 A/h, which can be adjusted by a long regulator arm, and it regulates a classic swiss pallet lever escapement.

Nice to see is the old AS hallmark at 12 o’clock. along with the gold or brass-colored version of the boards a clear indicative of the 1920s.

At 3 o’clock you can see the yoke winding mechanism, which was quite modern at the time.
