Description

CROSS-REFERENCE TO RELATED APPLICATION

BACKGROUND

Early mechanical watches serve the purpose of a time-indicating device, but now also act as a fashion accessory for consumers. The existing watch design for mechanical movement mostly adopts the traditional hour hand, minute hand, and second hand for time indication. The axes of the hour hand, minute hand, and second hand are typically all positioned at the same point, although some designs have them arranged at different positions on the watch face. The operation of the hands of a wristwatch is generally determined by a gear system of a wristwatch.
Watches evolved to include automatic movement such that watches may be self-winding. An automatic watch captures energy from the movements of the wearer's wrist using a weighted mechanism and stores the energy in a watch's mainspring.
Since the advent of automatic movement, quartz movement has been developed. A quartz watch relies on a battery, thereby eliminating the need for winding by the wearer. The battery in a quartz watch generates an electric current that creates a vibration in a piece of quartz inside the watch. This piece of quartz vibrates at a specific frequency to maintain the accuracy of the watch's time indication.
The design and purpose of the foregoing watches are to indicate time.

SUMMARY

The disclosure provides a case cap apparatus and a watch apparatus having a case back configured to be removably coupled to the case cap. This novel system advantageously permits a first removable case cap to be exchanged with a second removable case cap, for example, to swap out engravings or other personalization or alternative materials, such as different metals. When the case caps are exchanged, the case back remains in place protecting the watch movement control system.
In one beneficial implementation, a case cap retainer is coupled to the case back of the watch for removable coupling with the case cap apparatus. This variation permits removal and attachment of the case cap to the base back by a user without resort to a separate tool or other implement and without servicing by a professional jeweler.
In a first aspect, an example watch is disclosed. The watch includes (a) a housing having a first face and a second face and a cavity extending therebetween, where the first face includes a first bezel coupled to a first transparent watch crystal, (b) a disc disposed within the cavity between the first face and the second face and coupled to the housing, where the disc includes a watch face for indicating time, and (c) a case cap removably coupled to the second face of the housing, where the case cap comprises a casing having a first side configured to mate with the second face of the housing and a second side configured to be engraved.
In a second aspect, an example case cap for coupling to a case back of a watch is disclosed. The case cap includes (a) a casing that is circular and has a first side configured to mate with a case back of a watch housing and a second side includes a planar surface configured to be laser engraved or acid engraved, and (b) an opening arranged on the first side of the casing and configured to receive a case cap retainer therethrough, where the casing defines a cavity in communication with the opening, where the cavity is sized and shaped to receive at least a portion of the case cap retainer and to permit rotation of a retention rim of the case cap retainer.

DETAILED DESCRIPTION

Figures 1-20 depict a watch 100 that includes a housing 105 having a first face 110 and a second face 115 and a cavity 106 extending therebetween. The first face 110 includes a first bezel 111 coupled to a first transparent watch crystal 112. The watch 100 further includes a disc 120 disposed within the cavity 106 between the first face 110 and the second face 115 and coupled to the housing 105. The disc 120 includes a watch face 121 for indicating time. The watch 100 also includes a case cap 125 removably coupled to the second face 115 of the housing 105. The case cap 125 includes a casing 126 having a first side 127 configured to mate with the second face 115 of the housing 105 and a second side 128 configured to be engraved.
In one optional implementation, shown in Figures 2, 5-6, 9, 11-15, and 17-18, the watch 100 includes a case cap retainer 130 coupled to the second face 115 of the housing 105. The case cap 125 is removably coupled to the case cap retainer 130. As shown in Figure 6, the case cap retainer 130 has a support 131 at a first end 132 coupled to the second face 115 of the housing 105 and a retention rim 133 at a second end 134.
In this example implementation, as shown in Figure 7, the case cap 125 has an opening 135 arranged on the first side 127 of the casing 126 and is configured to receive the case cap retainer 130 therethrough. The casing 126 defines a cavity 136 in communication with the opening 135. As shown in Figure 17, the cavity 136 is sized and shaped to receive at least a portion of the case cap retainer 130 and to permit rotation of the retention rim 133 to a locked position on the housing 105 such that the retention rim 133 of the case cap retainer 130 is out of alignment with the opening 135 of the casing 126 of the case cap 125, as shown in Figure 18.
In an optional implementation, a shape of the opening 135 in the case cap 125 and a shape of the retention rim 133 are the same. For example, the shape of the retention rim 133 is oval (FIG. 9), triangular (FIG. 11), rectangular or square (FIG. 12), pentagonal (FIG. 13), or hexagonal (FIG. 14).
In another optional implementation, the watch 100 includes at least one locking mechanism 140 having reciprocal male 141 and female 142 components coupled to the first side 127 of the casing 126 of the case cap 125 and the second face 115 of the housing 105. In a further optional implementation, shown in Figure 16, the at least one locking mechanism 140 is in the form of a ball detent 142 coupled to or defined by one of the second face 115 of the housing 105 and the first side 127 of the casing 126 of the case cap 125 and a ball plunger 141, not limited to but including a capsa ball, coupled to the other of the second face 115 of the housing 105 and the first side 127 of the casing 126 of the case cap 125.
In operation, the male and female components 141, 142 of the at least one locking mechanism 140 are out of alignment when the case cap retainer 130 is received through the opening 135 of the casing 126 of the case cap 125 in an unlocked position. When the case cap 125 is rotated about the support 131 of the case cap retainer 130, the male and female components 141, 142 of the at least one locking mechanism 140 are aligned and mated together in the locked position. In various implementations, the at least one locking mechanism 140may provide haptic or audible feedback when the male and female components 141, 142 initially engage with each other.
In another optional implementation, as shown in Figures 17-18, the cavity 136 of the casing 126 of the case cap 125 is sized and shaped to permit the retention rim 133 of the case cap retainer 130 to rotate at least 15 degrees within the cavity 136. Rotation of the retention rim 133 in this manner causes the retention rim 133 to move out of alignment with the opening 136 in the case cap 125 such that the case cap is retained on the housing of the watch. The retention rim 133 may be rotated back into alignment with the opening 135 of the case cap 125 to remove the case cap 125 from the case back 115 of the watch 100. In a further example implementation, the cavity 136 of the casing 126 of the case cap 125 is sized and shaped to permit the retention rim 133 of the case cap retainer 130 to rotate up to seventy-five degrees.
In one optional implementation, the at least one locking mechanism 140 includes two locking mechanisms arranged 180 degrees apart on the second face 115 of the housing 105 and 180 degrees apart on the first side 127 of the casing 126 of the case cap 125.
In an alternative optional implementation, as shown in Figures 19-20, an outer circumference 124 of the case cap 125 contains at least one through-hole 145 configured to receive a removable connector in the form of a threaded screw, wherein the second face 115 of the housing 105 includes at least one threaded cavity 146 configured to receive the threaded screw when the at least one through-hole 145 of the case cap 125 is concentrically aligned with the at least one threaded cavity 146 in the second face 115 of the housing 105.
In an another optional implementation, shown in Figure 8, a second side 128 of the casing 126 of the case cap 125 includes a planar surface 129 configured to be laser engraved or acid engraved. In a further optional implementation, an outer circumference 124 of the case cap 125 is chamfered.
In a yet another optional implementation, as shown in Figures 2 and 16, the second face 115 of the housing 105 includes a second bezel 116 coupled to a second transparent watch crystal 117. This implementation permits a watch movement control system 150, including for example, gears and spindles, to be observed when the case cap 125 is uncoupled from the case back 115 of the watch 100. In an alternative implementation, the second face 115 of the housing 105 is opaque.
In yet another optional implementation, the disc 120 has a through-hole 122 arranged in the center of the disc 120. In this implementation, the watch 100 further includes a shaft 151 disposed within the through-hole 122 of the disc 120. The watch 100 includes at least one hand 123 for indicating time coupled to a first end 152 of the shaft 151 between the first face 110 of the housing 105 and a first side 113 of the disc 120. The watch 100 also includes a watch movement control system 150 coupled to the second end 153 of the shaft 151 between the second side 114 of the disc 120 and the second face 115 of the housing 105.
In a further optional implementation, the watch 100 includes a rotatable knob 155 coupled to the watch movement control system 150 and configured to move the at least one hand 123 for indicating time. The rotatable knob 155 is coupled to a side 107 of the housing 105 between the first face 110 and the second face 115.
In still another optional implementation, the watch 100 includes two pairs of lugs 160a, 160b extending from opposite ends 108a, 108b of the housing 105 between the first face 110 and the second face 115.
In a second aspect of the disclosure, the case cap 125 for coupling to a case back 115 of the watch 100 is provided. As used herein, the second face 115 of the housing 105 corresponds to the case back 115 of the watch 100. The case cap 125 includes a casing 126 that has a first side 127 configured to mate with the case back 115 of the watch housing 105 and a second side 128 comprises a planar surface 129 configured to be laser engraved or acid engraved.
Although for purposes of describing the case cap 125 and the case back 115 (i.e., the second face 115 of the housing 105), a watch 100 has been illustrated and described as being generally circular, it is to be understood that it is within the scope of the disclosure that the case cap 125 and the case back 115 may be made in any shape, such as square, rectangular, octagonal, oval, elliptical, triangular, or any other shape that may be desired.
In one optional implementation, the case cap 125 of the second aspect of the disclosure also includes an opening 135 arranged on the first side 127 of the casing 126 and configured to receive a case cap retainer 130 therethrough. The casing 126 defines a cavity 136 in communication with the opening 135. The cavity 136 is sized and shaped to receive at least a portion of the case cap retainer 130 and to permit rotation of a retention rim 133 of the case cap retainer 130.
The case cap 125 includes, in an example implementation, at least one male or female component 141, 142 of a reciprocal locking mechanism 140 coupled to the first side 127 of the casing 126. In one variation, the at least one male or female component 141, 142 of the reciprocal locking mechanism 140 includes at least one ball detent coupled to or defined by the first side 127 of the case cap 125.
