Description

Technical Field

[0001] This invention relates to a timepiece, and more specifically, to a wristwatch with an oriented bezel. Background Technology

[0002] Typical watches in this art may have a bezel; that is, a ring that surrounds the case. Two types of bezels are generally used: timing bezels and diving bezels. Timing bezels can move in both clockwise and counterclockwise directions, while diving bezels, used to visually track a diver's air supply by measuring dive time, rotate only counterclockwise. Other bezels may be purely decorative and may not move in either direction. No watch in this art incorporates a highly efficient double bezel design that is functional, water-resistant, and quick-operating.

[0003] This invention provides a watch bezel assembly having a double bezel, which utilizes an elastic device (e.g., a spring, a buffer, or a pawl) positioned within a channel formed between the bezels to allow for reverse rotation functionality. Double bezel functionality is not provided in the prior art. Summary of the Invention

[0004] As the foregoing discussion has shown, there is clearly a need for a reverse-rotating double-bezel watch assembly. Advantageously, such a device would overcome many of the difficulties and safety concerns raised.

[0005] This invention was developed in response to problems and needs that have not been fully solved or explored by currently available devices in the art. Therefore, this invention has been developed to provide a double-bezel watch assembly comprising: an annular outer bezel including a plurality of pawls adapted to engage teeth on an inner bezel; an inner bezel positioned within the outer bezel, the inner bezel having an outer surface including first teeth at first regularly spaced intervals, the first teeth adapted to engage the pawls; and the inner bezel having a lower surface including second teeth at second regularly spaced intervals.

[0006] The double-bezel watch assembly may be composed of a first tooth in a number of 20, 40, 60, 100, 120, and 180. Alternatively, the double-bezel watch assembly may be composed of a second tooth in a number of 20, 40, 60, 100, 120, and 180. The double-bezel watch assembly may also include an inner overhang flange adapted to hang over a portion of the watch dial surrounding the inner bezel.

[0007] The inner edge of the inner outer ring may define an inner hemispherical channel in which a first sealing ring is received. The lower flat surface of the outer outer ring may define a lower hemispherical channel adapted to receive a lower sealing ring. The top surface of the outer outer ring may slope downward toward the outer periphery of the outer outer ring.

[0008] The inner bezel and the outer bezel can rotate in opposite directions. The inner bezel and the outer bezel may have graduations.

[0009] A second type of double-bezel watch assembly is provided, comprising: a housing housing a watch dial having a raised circular support including lateral protrusions surrounding the watch dial; an outer bezel positioned outside an inner bezel, the outer bezel including a top surface; an outer flange descending from the downwardly sloping top surface; and outer teeth spaced at regular intervals around an inner surface of the outer flange; an inner bezel positioned within the outer bezel, the inner bezel including a plurality of inner teeth spaced at regular intervals around a lower surface of the inner bezel; and an annular inner lip positioned above the raised circular support of the housing; wherein the housing defines an annular channel surrounding the watch dial, the annular channel being sized to receive the inner teeth of the inner bezel; and wherein the housing defines a large spring recess annularly surrounding the watch dial, the large spring recess being sized to receive a large spring.

[0010] The double-bezel watch assembly may also include a small spring with a lever arm.

[0011] The outer surface of the inner ring and the inner surface of the outer ring can be grooved to form a sealing ring groove, which accommodates the sealing ring.

[0012] A lever arm groove may be provided below the internal teeth, and the size of the lever arm groove is set to receive a lever arm with a small spring.

[0013] A third type of double-bezel watch assembly is provided, comprising: a housing housing a watch dial; an outer bezel positioned outside an inner bezel, the outer bezel including: a top surface; an outer flange descending from the downwardly sloping top surface; outer teeth spaced at regular intervals around an inner surface of the outer flange; an inner bezel positioned within the outer bezel, the inner bezel including: a plurality of inner teeth spaced at regular intervals around a lower surface of the inner bezel; and an annular inner lip positioned above a raised circular support of the housing; wherein the housing defines: an annular channel surrounding the watch dial, the annular channel being sized to receive the inner teeth of the inner bezel; and wherein the housing defines a large spring recess annularly surrounding the watch dial, the large spring recess being sized to receive a large spring.

[0014] The watch dial can be centrally positioned between the outer bezel and the inner bezel. The double-bezel watch assembly may also include a sealing ring disposed between the case and the inner bezel, the sealing ring surrounding the watch dial.

[0015] The double-bezel watch assembly may further include a sealing ring disposed between the inner bezel and the outer bezel, the sealing ring surrounding the watch dial. The top surface of the outer bezel may be sloped downwards.

[0020] Figure 1 A bottom view of the inner bezel of the double-bezel watch / bezel assembly 10100 according to the present invention is shown.

[0021] The bezel assembly 10100 includes an inner bezel 10100 and an outer bezel 10200. The inner bezel 10100 and the outer bezel 10200 are rotatable in opposite directions along their axial axes. The watch face is disposed within a circular recess 10106 defined by the inner bezel 10100. In some embodiments, the inner bezel 10100 rotates counterclockwise in diameter, opposite to the hands, while the outer bezel 10200 rotates clockwise about the same axis as the hands.

[0022] The inner bezel 10100 includes a plurality of teeth 10102 spaced at regular intervals around the periphery of the inner bezel. In the illustrated embodiment, the inner bezel 10100 includes 60 teeth, but in other embodiments it may include 10, 20, 30, 40, 90, 120, or 180 teeth.

[0023] An annular lip 10104 surrounds the inner edge of the inner bezel 10100. The annular lip 10104 hangs over the housing and is operable to rest on a raised circular support 10410 of the housing 10400. A tooth 10102 is positioned below the lower edge of the annular lip 10104.

[0024] Flange 10106 surrounds the outer periphery of inner ring 10100. Flange 10106 includes a cylindrical sidewall that projects downward below tooth 10102.

[0031] The housing 10502 includes an annular channel 10411 surrounding the dial 10106. The channel 10411 is sized to receive the internal teeth 10102 and flange 10106 of the inner bezel 10100.

[0032] The lower inner surface of channel 10411 defines a large spring recess 10406. A spring or large pin 10700 is positioned within the large spring recess 10406. Spring 10600 may include a lever arm 10602, which, in the assembled watch 10500, is positioned within a lever arm recess 10502 below the internal teeth 10102 of the inner bezel 10100.

[0033] In various embodiments, the housing 10400 includes a raised circular support 10410 that spacees the watch crystal face from the inner bezel 10100. The raised circular support 10410 is secured to or formed as a single integrated member with a lateral protrusion 10408 that surrounds the raised circular support 10410.

[0034] In the assembly configuration, the tension spring groove (i.e., the sealing ring groove 10510) is defined below the lateral protrusion 10408, and the tension spring and / or sealing ring are received in the tension spring groove.

The side edge 310 may include 20, 30, 50, 60, 100, 120, or 180 teeth. In various embodiments, the number of teeth on the side edge 310 differs from the number of teeth on the lower edge 308, such that fractional distances between the teeth can be achieved by simultaneously operating the bezel / dials 102, 104.

[0061] The inner ring 104 is positioned within an annular groove defined by the outer ring 102. The inner ring 104 and the outer ring 102 may form a friction fit, a snap fit, or otherwise combine in a manner known to those skilled in the art.
