#CMT# #/CMT# The watch has a timepiece movement including a tourbillon (10) whose rotary cage (14) is connected to an opaque part of the movement by fixed metallic support and by a kinematic connection. A continuous annular gap (20) allows only the visibility of an index (17) on the top and not visibility of other movement elements. The gap is extended from a circular window (11) between an index perimeter, and a visible part of the cage. The support and the connection comprise transparent annular disks and a transparent rotary base plate, respectively, in the gap. The disks and the plate are made of sapphire. #CMT#USE : #/CMT# Watch i.e. wristwatch. #CMT#ADVANTAGE : #/CMT# The transparent disks and the base plate are made of sapphire, thus assuring high mechanical resistance of the watch, while ensuring high wearing comfort of the watch. The continuous annular gap allows only the visibility of the indicator element on the top and not the visibility of other movement elements, thus assuring the aesthetic appearance of the watch, while permitting a user to see the indication of hour. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of a wristwatch. 1 : Case 6 : Opaque dial 10 : Tourbillon 11 : Circular window 14 : Rotary cage 17 : Index 20 : Continuous annular gap. |
