This bank alarm timer uses two independent Seth Thomas movements within one unit. Many alarm timers had two separate timers each contained within a wood case and often used a lesser quality and much larger Seth Thomas #10 movement. A few were single units utilizing standard time lock movements within a similar style case or a small metal case. The Seth Thomas movements used here appear to have been originally made for the marine market. The design of the case and glass indicates that this was intended for a proof of concept and would have entailed an unnecessary expense for a production model.
Many alarm timers were expected to be set at the time the alarm was to go on guard, this one allowed the operator to set it ahead of time and a separate warning would sound when time was approaching for the timer to go on guard to alert the personnel to close up the bank.
