bimetallic screw balance
regarding the dial signature, cased by Ami LeCoultre (LeCoultre-Piguet), and after the additional movement signature finished by Blancpain
made before 1932, because later Blancpain signed movements with Rayville (anagram for Villeret)
differences not known between 90-96

Example, year: signature; shock device
ca. 1930: A. LeCoultre, Blancpain, Swiss, 17 Jewels
