A., Le Locle, Switzerland, a firm of Switzerland Application May 9, 1951, Serial No. 225,394 In Switzerland May 12, 1950 1 Claim.

My invention has for its object a universal watch including on one hand time-indicating members and on the other hand a rotarydial controlled by the clockwork and indicating universal time in register with a stationary dial.

This watch is characterized by means for manually shifting said rotary dial independently of the above mentioned indicator members, the watch being designed so as to allow an adjustment of the rotary dial.

I have illustrated by way oi example and by no means in a binding sense, three preferred embodiments of the objects of my invention in accompanying drawings, wherein:

Figs. l, 3 and 5 are plan views respectively of each of said embodiments, certain portions of which are torn oli.

Fig. 2 is a cross-section through line iI-II ci Fig. 1.

Fig. 4 is a cross-section through line [V-IV oi "i Fig. 3.

Fig. 6 is a cross-section through line VI--VI oi Fig. 5.

In Figs. 1 and 2, the Watch illustrated carries hands I, 2 and 3 for indicating respectively hours, minutes and seconds. The stationary dial shown at 4 and carrying the indication of hours at its .periphery is annular. A dial 6 is revolubly mounted inside and coaxially with the dial 4. Said rotary dial carries the names of various large cities, symbolizing different time-belts, at its periphery and it is intended to give out universal time on a 24-hour scale 8 carried by the cooperating inner periphery of the stationary dial 4. It is possible, just as well, to provide this 24-hour scale 8 on the rotary dial 6 and the names of the different large cities 'I on the stationary dial 4. The drive of the dial 6 under the action of the clockwork is provided by a wheel 9 meshing with an our wheel shown at I0 and driving through the agency of a friction coupling a ratchet wheel I I rigid with a wheel I2 and this latter wheel drives a toothed ring I3 fitted over an embossment 6a of the dial 6. Friction between the wheels 9 and II is ensured by a coil spring I4. The ratio of the gearing between the different wheels and pinions of the gearwork driving the rotary dial 6 is such that said dial executes one revolution per 24 hours.

The watch illustrated includes a hand-operable resetting device for the dial 6. This resetting arrangement includes a pusher I5 pivotally secured at I 6 and the outer end I5a oi which acts on a lever I1, the nose-shaped end Ila of which is adapted to cooperate with the ratchet wheel II. Spring blades I8 and I9 serve for returning the pusher I5 and the lever I? respectively back into their inoperative positions. The operation of the pusher I5 producesthus an angular shifting of the dial t and said shifting is not transmitted to the other indicating parts by reason of the frictional engagement between the wheels 9 and II.

The setting of the hands of said watch is performed in two different manners:

When the time belt remains the same and it is merely desired to set the watch right after a stoppage or an irregular working of the watch, the person wearing the Watch acts on the button shown at 20 so as to produce an angular shifting of the hands I and 2 and also of the dial 6. If, in contradistinction, the time-setting is required on account of a change in the time belt, it is necessary to move the button 2S in order to set the hands I and 2 by the time oi the further time belt in which the wearer of the watch enters. But this time setting shifts the dial 6 which should not in this case move with the hands. The wearer of the watch acts then on the pusher I5 so as to return the dial t into the position it was occupying at the moment considered and that should not have been modified.

In the second embodiment illustrated in Figs. 3 and 4, the stationary dial 2l carrying the scales of I2 and 24 hours is located centrally and inside the rotary dial shown at 22 which is annular and carries the names of the large reference cities. Said dial is rigid with a toothed ring 23 meshing with a pinion 24 rigid with a ratchet wheel 25. The wheel 25 is driven in its turn by a similar wheel 28 rigid with a pinion 2l. The pinion 27 is driven by intermediate wheels illustrated at 28 through the agency of an intermediate pinion 29. The dial 22 executes one revolution per 24 hours. The two

wheels

25 and 25 forming a catch system are adapted to cooperate with one another through the agency of a spring blade 38 shown in Fig. 3. The resetting arrangement of the dial 22 includes a pusher 3i controlling a catch 32 cooperating with the pinion 24. The position of the series of names oi large cities and of the annular 24-hour scale may also be interchanged as precedingly.

In the last embodiment illustrated in Figs. 5 and 6, the rotary dial is constituted by an annular dial designated by 33 and carrying a 24- hour scale. Said rotary dial is located between an inner stationary dial 34 carrying an annular 12-hou11 scale and an outer annular stationary dial 35 carrying the names of the large reference cities. The annular dial 33 is Arigid with a toothed ring 3B that is controlled by the hour wheel 31 through the agency of a gear work including a ratchet Wheel. A dial-resetting arrangement similar to that already described allows shifting the annular dial 33 `independently of the indicator hands.

In a modication, the manual shifting of the rotary dial may be performed by means of. a.

ring replacing the pusher meansr even .by means of a rotary bezel.

What I Claim is:

In a Watch, the combinationof .timer-indicata.- ing parts, a clockwork, a transmission 'operatively connecting the clockwork -with .said-parts, a stationary dial cooperating with said.; parts, a rotary dial coaxial with the stationary dial, means controlled by the transmission `for'driving the rotary dial including a shiftable member adapted to be shifted .with reference to' the transmission to allow correction of :theangular setting-of the rotary dial, hand operable means member and thus set the rotary dial and two registering annular scales carried respectively by the cooperating peripheries of the two dials and including respectively a subdivision in hours and a subdivision in time belts.
