The PTS Resources caliber Z2031 (Shandong Liaocheng Zhong Tai Watch Company?) is a 22 jewels automatic watch movement. This caliber is made in China. There is a similar caliber Z2032.

Functions

The Z2031 is a multi-function automatic movement with an open balance wheel at 6:00, second time zone (dual time) subdial at 9:00 and a day/night (sun/moon) indicator at 12:00. The dual time subdial is a true second time zone indicator and is set independently by turning the crown backwards in time setting mode.

Double Barrel

The PTS caliber Z2031 features double barrels (two mainsprings). Although this is a feature used to get more power reserve out of a watch movement, PTS Resources does not list the power reserve in their tech information.

Svalbard Watches uses the “PTS Resources 5833” automatic movement, in at least two of their watches, the Expedition FL44 and the Noonday FL17.

I wonder if the Jazz model of Ingersoll could be fitted with small seconds hand on the 6 oclock exposed mechanism. Apparently, it doesn’t have at the moment.
