Authentication Notes

Movement

CriticalProbable

Count the jewels rather than reading the grade marking

The value gap between a 992B and a 950B rewards altering the grade name engraved on the movement. The check is physical and conclusive: a 950B has 23 jewels and a 992B has 21, and the additional jewels are visible. Verify the count, and verify that the serial prefix matches the grade claimed, before accepting an engraved designation.
