The AHS caliber 41 is similar in size and functions to the caliber 40. The only difference is, that the balance wheel runs in synthetic jewels, which is good for the precision, but bad for the survival of bad shocks.
This movement is also available in different versions; the one displayed here has got a double plate on the balance.
