Ingersoll automatic caliber IN 886. It is basically a Chinese version of the 7750. This movement was found in an Ingersoll Bison 21 Buffalo model. Chinese-made with 35 jewels. Ingersoll claims this movement should stay accurate between -30 to +30 seconds per day when worn under normal conditions. This is one of the few chronograph movements ever used by Ingersoll. Most of their watches look like chronographs, which pushers and all, but do not actually have a functioning start and stop mechanism.
