Claim 12

A timepiece according to claim 8 wherein said revolving members comprise an hour and a minute hand.

Claim 13

A timepiece according to claim 7 further comprising a means for adjusting the position of said center of gravity of said revolving member and said movement means such that said center of gravity revolves about said bearing point in a substantially circular path.

Claim 14

A timepiece having a face comprising: at least one revolving member rotatably coupled to said face at a bearing point for indicating the time; a movement means provided said revolving member causing the center of gravity of said revolving member and said movement means to rotate about said bearing point whereby said revolving member is caused to revolve about said bearing point as a result of a gravitational force acting on said center of gravity, said movement means comprising: a timepiece movement having a rotating output which rotates with the fixed period; and a weight fixed to said output whose center of gravity is eccentric relative to the access of rotation of said output; and a means for adjusting the position of said center of gravity of said revolving member and said movement means such that the center of gravity revolves about said bearing point and substantially circular path, said means for adjusting the position of said center of gravity comprising a weight whose position relative to said bearing point is adjustable.

Claim 15

A timepiece having a face comprising: at least one revolving member rotatably coupled to said face at a bearing point for indicating the time; a movement means provided said revolving member causing the center of gravity of said revolving member and said movement means to rotate about said bearing point whereby said revolving member is caused to revolve about said bearing point as a result of a gravitational force acting on said center of gravity, said movement means comprising: a timepiece movement having a rotating output which rotates with the fixed period; and a weight fixed to said output whose center of gravity is eccentric relative to the access of rotation of said output; and a means for adjusting the position of said center of gravity of said revolving member and said movement means such that the center of gravity revolves about said bearing point and substantially circular path, said means for adjusting the position of said center of gravity comprising a weight whose position relative to said bearing point is adjustable.

Claim 16

A timepiece having a face comprising: at least one revolving member rotatably coupled to said face at the bearing point for indicating the time; a movement means provided in said revolving member for causing a center of gravity of said revolving member and said movement means to rotate about said bearing point whereby said revolving member is caused to revolve about said bearing point as a result of a gravitational force acting on said center of gravity, said movement means comprising: a timepiece movement having a rotating output which rotates with the fixed periods; and a weight fixed to said output whose center of gravity is eccentric relative to the access of rotation of said output; a means for adjusting the position of said center of gravity of said revolving member and said movement means such that such center of gravity revolves about said bearing point in a substantially circular path; and an external manipulating part which corrects the time indicated by said revolving member by causing said movement means to rotate said center of gravity about said bearing point in response to an input via said external manipulating part.

Claim 17

A timepiece having a face comprising: at least one revolving member rotatably coupled to said face at the bearing point for indicating the time; a movement means provided in said revolving member for causing a center of gravity of said revolving member and said movement means to rotate about said bearing point whereby said revolving member is caused to revolve about said bearing point as a result of a gravitational force acting on said center of gravity, said movement means comprising: a timepiece movement having a rotating output which rotates with the fixed periods; and a weight fixed to said output whose center of gravity is eccentric relative to the access of rotation of said output; a means for adjusting the position of said center of gravity of said revolving member and said movement means such that such center of gravity revolves about said bearing point in a substantially circular path; and an external manipulating part which corrects the time indicated by said revolving member by causing said movement means to rotate said center of gravity about said bearing point in response to an input via said external manipulating part.
