' WRIST WATCH Filed Dec. 16, 1929 2 Sheets-Sheet 2 awww Patented Apr. 26, 1932 UNITED STATES EMILE FREY, OF BIENNE, SWITZERLAND WRIST-WATCH Application filed December 16, 1929, Serial No. 414,518, and in Switzerland April 23, 1929.

The present invention relates to Wrist watches. The object of the invention is to provide wrist watches applied more closely to the curved surfaces of the wrist and it consists in a combination of a plate and bridges where plate and bridges have their surfaces facing the casing curvilinear and the surfaces facing the wheels plane, and where owing to a special arrangement of parts the bulk of the watch has been reduced without diminishing the size of parts accordingly.

In the accompanying drawings one embodiment of the invention has been illustrated. In the drawings Fig. 1 is a section on line II of Fig. 2, Fig. 2 is a plan view, Fig. 3 is a side elevation, Figs. 4 and 5 are diagrams showing more clearly by a plan and a section the particular arrangement of parts.

According to the Figures 1 to 3 the plate 79 is provided on its inside surface with recesses for the different wheels. These recesses are all parallel to each other and perpendicular to the axes of the Wheels. The outside surface however of the plate is convex so as to fit a casing of the same shape. The bridges, 0 0 which are fixed to the plate are limited on the side of the wheels by planes par allel to the planes of the plate and on the outside by a concave surface fitting that of the casing not shown. 0 may be curved on the outside also, if necessary.

According to the present invention in the arrangement of parts according to the Figs.

4 and 5 the lever escape wheel d is not located nearly in the same plane with the pivoted detent as in ordinary wrist Watches, but directly above the same, as shown in Fig. 5. This arrangement achieves the advantages while keeping the rest of the movement very low elevating end n of the casing for locating there the balance wheel f, spring f balance cock f and index f Thus the movement utilizes the space as much as can be. Not only the whole length of the movement is shortened, but also the dial has obtained a solid base, the uniform thickness of the movement has rather diminished than increased and the same size of the parts has been maintained.

What I claim is:

1. In an oblong wrist watch having a case curved on both sides and all wheels disposed in parallel planes, a plate and bridges po sitioned on one side of such plate said plate and said bridges having their surfaces facing the case conforming to the contour thereof and their surfaces facing the wheels plane.

2. In an oblong wrist watch having a case curved on both sides, a plate for supporting the Wheels of the watch, said plate having the surface disposed on the side of the case of convex form to support a dial and the surfaces on the side of the wheels of rectilinear planar form, and bridges having the surface disposed on the side of the case of con- CEUQ form.

3. In an oblong wrist watch having a cas ing and movement curved according to the rounded form of the wrist, a winding mechanism positioned relatively near the longitudinal center of the casing, a lever escape wheel provided above a portion of the winding arrangement and a balance Wheel and associated part-s positioned at a higher level and partly overlapping said lever escape wheel within the curved end of the movement.

4. In an oblong wrist watch having a casing and movement according to the rounded form of the wrist, a winding device with the winding button arranged relatively near the longitudinal center of a side of the casing, an escape wheel provided above a portion of said winding device and a balance wheel, spring, cock and index positioned above said escape wheel in the curved end of the movement.

In testimony whereof I affix my signature.

EMILE FREY.
