FIG. 1 illustrates an example of a watch band 100 according to some embodiments of the present invention. As shown in FIG. 1, watch band 100 includes a first section 102 and a second section 104. As shown in FIG. 1, watch band 100 couples a watch 106 with a watch 108 where first section 102 and second section 104 couple watch 106 and watch 108 into a single wearable watchband with two watches. Watch 106 and watch 108 can be any pair of watches. However, watch band 100 can be used to mount a decorative watch, watch 106, with a highly functional smart digital watch, watch 108. For example, for those that do not wish to abandon wearing of an expensive high-end watch but would also like the functionality of a smart digital watch, watch 106 can be a high end watch and watch 108 can be a smart digital watch.
As shown in FIG. 1, sections 102 and 104 can include connectors to mate with watches 106 and 108. The example shown in FIG. 1 is a standard pin type, or spring bar, connection so that section 102 couples to watch 106 with connector 112 and to watch 108 with connector 110 while section 104 couples to watch 106 with connector 116 and couples to watch 108 with connector 114. As is further discussed below, other connections can be made. Further, in some embodiments section 102 and 104 can be formed in a single piece with a holder for watch 108 formed in the now single piece band. Additionally, in some embodiments a clasp may be formed in section 102, section 104, or both. Band 100 can be formed of any material capable of holding watch 106 and watch 108. For example, band 100 can be formed as an expansion bracelet, can be formed of leather, simulated hides, metal, precious metals, cloth, fabric, nylon, rubber plastic, composite materials or other material. Band 100 can be formed to various designs and patterns and can be formed of combinations of materials.
FIGS. 2A and 2B illustrate one way of wearing band 100 while FIGS. 3A and 3B show another way of wearing band 100. In some examples, band 100 may be configured such that watch 106 is on the opposite side of the band from watch 108. In some examples, the links of band 100 on either side of watches 106 and 108 may be of equal length and/or are symmetrical such that watches 106 and 108 are on opposite sides of the band. In some examples, band 100 may be configured such that watch 108 is placed on the outer wrist while watch 106 is placed on the inner wrist when worn. In some examples, the links of band 100 on either side of watches 106 and 108 may be of different length and/or are asymmetrical, such that the watches are not placed on the opposite sides of the band. For example, band 100 may be configured such that when watch 108 is placed on the outerwrist, watch 106 may be placed on the side of the wrist. In some examples, band 100 may be configured to connect additional watches.
FIGS. 4A and 4B further illustrate band 100 with watches 106 and 108 in place. FIG. 4A illustrates the perspective towards watch 106 while FIG. 4B illustrates the perspective of band 100 from watch 108.
