Abstract

Abstract A correction device for a watch having a plurality of adjustable time displays utilizes a single control element extending externally of the watch and adapted to be manually operated to adjust the plurality of time displays. Operating means operatively associates each of the adjustable time displays with the control element whereby the latter is operable to adjust each of the time displays. By way of example, the control element may be used to adjust a first time display indicating local time and a second time display indicating the hour in a time zone other than that in which the wearer of the watch is located.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 131 words
A correction device for a watch having a plurality of adjustable time displays, comprising a control element extending externally of said watch and adapted to be manually manipulated to adjust said plurality of time displays, and operating means operatively associating each of said adjustable time displays with said control element whereby the latter is operable to adjust each of said time displays, wherein said operating means comprises a setting lever operable to be pivoted by longitudinal displacement of said control element, a setting gear lever, biasing means urging said setting gear lever into engagement with said setting lever, a setting gear rotatably mounted on said setting gear lever, and a clutch gear rotatable by said control element, said clutch gear driving said setting gear which in turn rotates a correction gear.
Claim 2
Dependent Claim 131 words
A correction device for a watch having a plurality of adjustable time displays, comprising a control element extending externally of said watch and adapted to be manually manipulated to adjust said plurality of time displays, and operating means operatively associating each of said adjustable time displays with said control element whereby the latter is operable to adjust each of said time displays, wherein said operating means comprises a setting lever operable to be pivoted by longitudinal displacement of said control element, a setting gear lever, biasing means urging said setting gear lever into engagement with said setting lever, a setting gear rotatably mounted on said setting gear lever, and a clutch gear rotatable by said control element, said clutch gear driving said setting gear which in turn rotates a correction gear.
Claim 3
Dependent Claim 122 words
A correction device for a watch having a plurality of adjustable time displays, comprising a control element extending externally of said watch and adapted to be manually manipulated to adjust said plurality of time displays, and operating means operatively associating each of said adjustable time displays with said control element whereby the latteR is operable to adjust each of said time displays, wherein said operating means comprises a correcting finger and lever means operatively connected between said control element and said correcting finger whereby longitudinal displacement of said control element pivots said correcting finger, and means operatively connected between one of said time displays and said correcting finger operable to rotate said one time display upon pivotal movement of said correcting finger.
Claim 4
Dependent Claim 122 words
A correction device for a watch having a plurality of adjustable time displays, comprising a control element extending externally of said watch and adapted to be manually manipulated to adjust said plurality of time displays, and operating means operatively associating each of said adjustable time displays with said control element whereby the latteR is operable to adjust each of said time displays, wherein said operating means comprises a correcting finger and lever means operatively connected between said control element and said correcting finger whereby longitudinal displacement of said control element pivots said correcting finger, and means operatively connected between one of said time displays and said correcting finger operable to rotate said one time display upon pivotal movement of said correcting finger.
Claim 5
Dependent Claim 36 words
A correcting device according to claim 2 wherein said means operatively connecting said lever means with said control element comprises a plurality of pivotal levers and spring means biasing said levers in a predetermined rotational direction.
