A mechanical timer, used by the italian navy during the 2nd world war. To our knowledge today, these type of timers were used in warheads which have been carried by SLC torpedos. They have been inserted into a circular cavity on the starboard side of the warhead.
The countdown scale (delay mechanism) is adjustable to max. 10 hours. The case is made of brass. As the adjustable scale is not luminous, it had to be set before the mission (usually in total darkness underwater / night mission) started. Once the explosive was placed under the target, the timer had just to be activated.
