Abstract
Abstract A timepiece includes a pair of rotatable discs carrying respectively hour and minute indicia on one surface adjacent their peripheries. The indicia are arranged to pass, on rotation of the discs, adjacent the geometric central axis of the case of the timepiece. A window is formed at a position corresponding to the geometric central axis of the case, in a cover of the case, for viewing the indica.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
191 words
A wrist watch having a generally rectangular case having a lengthwise direction and a widthwise direction, a movement in said case comprising a mounting plate which is disposed eccentrically of said case with the center of said plate spaced in a lengthwise direction from the center of said case, a dial overlying said plate and having window means disposed at the center of said case, a minute disc rotatably mounted on said plate and overlying said movement, said minute disc being disposed between said plate and dial and having at its periphery indicia indicating minutes selectively visible through said window means, an hour disc rotatably mounted on said plate at the periphery thereof and extending beyond said plate, said hour disc being disposed beneath said dial and having at its periphery indicia indicating hours selectively visible through said window means, and means operatively connecting said discs with said movement to be driven by said movement, said window means, discs and indicia being arranged to present the hour indicia and minute indicia in line with one another in a direction lengthwise of the case with the minute indicia following the hour window.
Claim 2
Dependent Claim
191 words
A wrist watch having a generally rectangular case having a lengthwise direction and a widthwise direction, a movement in said case comprising a mounting plate which is disposed eccentrically of said case with the center of said plate spaced in a lengthwise direction from the center of said case, a dial overlying said plate and having window means disposed at the center of said case, a minute disc rotatably mounted on said plate and overlying said movement, said minute disc being disposed between said plate and dial and having at its periphery indicia indicating minutes selectively visible through said window means, an hour disc rotatably mounted on said plate at the periphery thereof and extending beyond said plate, said hour disc being disposed beneath said dial and having at its periphery indicia indicating hours selectively visible through said window means, and means operatively connecting said discs with said movement to be driven by said movement, said window means, discs and indicia being arranged to present the hour indicia and minute indicia in line with one another in a direction lengthwise of the case with the minute indicia following the hour window.
Claim 3
Dependent Claim
23 words
A wrist watch according to claim 1, in which said indicia on said minute disc comprises the numeral 0 to 55 by 5''s.
Claim 4
Dependent Claim
65 words
A wrist watch according to claim 1, in which said plate has two opposite straight sides extending along opposite sides of said case and two opposite arcuate sides one of which extends approximately to one end of said case and the other of which is spaced from the opposite end of said case by a distance equal approximately to the radius of said hour disc.
Claim 5
Dependent Claim
52 words
A wrist watch according to claim 1, in which said window means comprises two adjacent windows, one for said hour indicia and the other for said minute indicia, said window for said minute indicia having a greater extent in a widthwise direction of said case than said window for said hour indicia.
Claim 6
Dependent Claim
34 words
