Cal. AS 1475 is a historic hand-winding alarm movement from A. Schild. Produced from 1954 through 1970, the movement was updated with date and faster balance before, but went out of production around 1974. The design was apparently copied by the Russians, where it remains in production by 1st Moscow Watch Factory. Cal. AS 1475 was one of the most widely-produced alarm calibres, with over 781,000 made, plus an indeterminate number produced later by Poljot.
Poljot 2612.1
Russian maker 1st Moscow Watch Factory, sold as Poljot (Russia), Sekonda (UK), and Cardinal (Canada), produced an almost-exact copy of Cal. AS 1475 starting as early as 1959 and continuing to the present time. The movement is commonly called the Poljot 2612 or 2612.1. This movement is often used today, typically with decoration and other modification, rather than the original Swiss movement. Often, the movement is referred to as “AS 1475” or some similar variation using the number “1475” to reference the historic basis for this movement. Note that the Russian version is usually indicated to have 18 rather than 17 jewels.
AS 1475 Operation
These A. Schild movements have two crowns located at 2:00 and 4:00 on the dial. As is the case with the Jaeger-LeCoultre Memovox, the crown at 2:00 is dedicated to the alarm function, while the one at 4:00 is used for timekeeping. However, unlike the Memovox, the alarm is enabled only when the crown is pulled.
- Crown at 2:00
- Wind alarm spring, alarm disabled
- Set alarm time (backward only), alarm enabled
- Crown at 4:00
- Wind main spring
- Set time (drag alarm in reverse)
