We have been working on identifying this one for a while - Gruen verithin pentagonal pocketwatch - for another watchmaker. It needs a staff (both pivots are broken) that I am trying to find a staff for, specs for a staff, or someone to repivot it for me. Attaching pictures to show watch, any help would be appreciated.

We have managed to track down that it is a Swiss chronometer extra precision and know that none of the book info for a V1 is correct for this watch. The balance has the roller jewel mounted in the arm of the balance itself. The guard for the roller is a separate unit at the very base of the staff. Would like to know more about the watch, it's specs, and origin. The watch identifies as a V1 via labeling and fingerprinting but is a 21 jewel chronometer version instead of a 17 or 19 jewel.

We have tried both staffs that are for a V1 and they do not fit
