ARMING CLOCKS |
UES I |
The UES I (original model - with soluble washer; revised model - without soluble was-her) was first hydrostatic arming clock used in German sea mines. To operate properly, this clock requires constant hydrostatic pressure in depths of 17 feet or more; after a continous run of 20 to 30 minutes the mine is armed. This clock was replaced by the UES II. |
