    I picked up a movement that seems to have two barrels for the time train. The movement is marked ST on the left and the number 10 on the right. it's a balance wheel mvt. What is it from. Thanks, Jack

    Welcome to the NAWCC Message Board Jackk nyc.

    You ask what the ST #10 movement was used for. The answer is "just about everything imaginable in time measurement and control."

    The ST #10 movement is/was very reliable and versatile. It was sometimes cased in a large bronze water-tight case like a steam gauge and used in boiler rooms. And it was cased in a simple wood box with a 24 hour dial and equipped with electrical contacts to control entry alarms for banks and other secure locations. It was used with a commutator to control public musical chimes and bells. It was used in many temperature and humidity recording instruments to move the chart paper.

    An finally, a very few were modified by the M. Low company during WWII with specially designed, very accurate escapement to be used at sea as a reliable precise timer.

    Some are found in "plain-old-clocks" too.

    Where did you locate your ST#10 clock movement and where or how do you plan to use it?

    Thanks, I found it at a flea market. I was going to use it to practice overhauling. Is it only an 8 day mvt.?

    Mine is sitting in a brass ship's clock case and is labeled "US Navy" on the dial. It does not have the precision escapement made by Low. So maybe it was just a timekeeper in the boiler room.
