Sonnerie Souveraine
Wristwatch with an inverted grand
strike/small strike chiming mechanism, is a unique piece invented
and made by Geneva chronometer-maker, F.P. Journe. It was completed
in 2000.
Journe's own construction puts the twin striking hammers under
the dial where they are visible through an aperture.
The inversion means that the complex and exact steelwork of the
chiming and repeating mechanisms can be admired through the
sapphire-crystal display back for the first time.
No less original is the dial of silver on gold, with central hours
and retrograde minutes, a power-reserve indicator and strike selection.
-
The button at 4 o'clock on the
platinum case sets the chime:
-
small strike which chimes
the hour and the three quarters in passing,
-
grand strike which repeats
the hour at the quarter, or silence.
-
The button at 2 o'clock releases
the minute-repeater.
-
The 13-lignes movement in a 40mm
diameter case contains 450 parts for a height of 6.8mm
and runs in 33 jewels.
-
The crown winds two barrels,
one for the chime and repeater, the other for a 36-hour movement
beating at 21,600 v/h.
