#CMT# #/CMT# The device has a spiral drive mobile (1) engaged with a driven mobile (2), where shapes and profiles of the drive and driven mobiles are determined to obtain a gear ratio between the drive and driven mobiles, that varies based on relative angular positions of the drive and driven mobiles. The driven mobile is integrated with an indicator unit i.e. hand, such that the device displays power reserve of a timepiece in a non-linear manner. The drive mobile is integrated with a wheel (3) engaged with a power reserve wheel (4). #CMT#USE : #/CMT# Indicating device for use as a non-linear sectoral power reserve display on a dial of a timepiece i.e. wristwatch (all claimed), to indicate power reserve of the timepiece. #CMT#ADVANTAGE : #/CMT# The driven mobile is integrated with the indicator unit such that the device displays the power reserve of the timepiece in a non-linear manner, thus assuring precise, reliable and clear reading of the power reserve when the wristwatch reaches the end of the power reserve. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of a part of a power reserve indicating device. 1 : Spiral drive mobile 2 : Driven mobile 3 : Wheel 4 : Power reserve wheel 7 : Arbor of hand. |
