Note: The type of lever escapement used in this watch is drawn and described in G. Daniels, The Art of Breguet, pp. 306, 307 although the banking fork is slightly different being off-set to one side of the lever tail. An all-or-nothing system is incorporated in the repeating train allowing the hammer to engage only when the pendant is fully depressed.
