You have a Waltham Model 11609 , Type A, No. 105 timer/stopwatch. The large hand measures seconds in 1/5 sec. increments and the small hand measures minutes up to 30 min. This is one of many stop watch variations made by Waltham. Info from Military Timepieces by Whitney. As to exactly what it was used for, no idea.
