HANDS Original


The present watch is in extremely good condition. It is also very high quality, being fitted with a Willis dial and a thief-proof swivel bow. The escapement is particularly well finished and employs a double-overcoiled balance spring.
Grande Sonnerie Striking: both the hours and the quarters are struck at each quarter.
Petite Sonnerie Striking: "ting-tang" quarters are struck at the quarter hours, but in which the hour is only struck at the hour.
