35 jewels
The Ingersoll caliber 735 is a Chinese-made automatic movement with 35 jewels, rated for accuracy within -30 to +30 seconds per day under normal wear conditions. Its open balance wheel design places the balance visible at 6:00 on the dial side but keeps it hidden from the caseback. The movement includes day, date, and month complications. It powers the Bison No. 18 IN4506 model.
