Ingersoll watches claims this movement should stay accurate between -30 to +30 seconds per day when worn under normal conditions.

Dual Time Zone Instructions

This movement is equipped with a dual time complication. The subdial at 9:00 gives you the time in a second time zone. To set the two times:

  1. With the crown pulled out one click to position 1, turn the crown counterclockwise to set the small dual time dial.
  2. Once the dual time is set, turn the crown clockwise to set the local time.
  3. Push the crown back in to position 0 (winding position).

In the Ingersoll manual, they state the following:

“Over wind of the spring may cause damage to the mainspring. Only wind the spring as far as it will go but not beyond.”

Base Caliber: PTS Resources/Shandong Liaocheng Zhong Tai Watch Company Z2031/Z2032(Boonville) Z2033/Z2034(Ulzana)

The two watches use slightly different movements based on the balance wheel anchors.

These movements have dual mainsprings.

This is not an ‘unknown’ reserve, because it s a 42-hour movement reserve.

It has “dual mainsprings” but such a low power reserve when they can just accomplish the same thing with one mainspring right? If one mainspring is broken can the watch still work with the other mainspring at half the power reserve?

Not really. My earnshaw uses the same movement and lasts for over a week without being wound, just sat on a desk. It makes a difference

What earnshaw do you have? Does it have seconds hand at the 6h position? I have Ingersoll theJazz, and I wonder why I dont have the seconds hand at the bottom, contrary to what this article say.

Hi djpahit, the Ingersoll Jazz is very similar to the Ingersoll Boonville, but one big difference is that for some reason they decided not to attach a seconds hand to the gear at 6:00. Check out this piece.
