This the movement fitted to the Ball Trainmaster Cannonball. The base of this movement is from Soprod SA. It is a 49 jewel, 28000vph with a 38hour power reserve that is modified.

Base probably a 2824. Not a big fan of modular chronos, although the looks of this one are spectacular.

Keep in mind that the design changed, and the stop second hand does not have a tritum tube or a the RR symbol.

Beautiful dial, striking watch.

Soprod is a great Swiss movement assembler that supports the mid-price Swiss watch industry. They also supply Louis Erard among other Swiss watch makers.

The original base movement is probably ETA 2824 with 25 Jewels and it was modified to 49 jewels to accomodate the Cannonball's complications.
