Abstract: A watchwinder adapted for home use or in a retail store environment includes a horizontal dovetail groove or channel on the top, bottom and side surfaces of the watchwinder housing which cooperates with a removable interlocking bar or rail of mating dovetail shape to selectively and detachably interconnect adjacent watchwinders arranged in a vertical or side-by-side relation. The grooves preferably extend across the horizontal dimension of the watchwinder to a point short of the front of the housing for concealment purposes, and are made relatively wide in relation to the dimensions of the housing to improve rigidity of an interlocked grouping of watchwinders and to simplify assembly. Preferably, the channels are of equal size and shape and spaced equidistantly apart. An array of interlocked watchwinders can be built up to varying size and shape, and one or more of the watchwinders can be selectively removed from anywhere within the array without disturbing the others.

In the armor assembly, a timepiece movement which has a movement main body and a winding stem attached to this main body so as to be capable of being inserted into or detached from it and connected to the crown, and a dial are built, and a winding stem attachment/detachment mechanism which makes an insertion/detachment of the winding stem into/from the main body possible is provided.
Abstract: An electronic timepiece with a solar cell includes a timepiece movement, a timepiece case for housing the timepiece movement, a casing ring for housing and holding the timepiece movement in the timepiece case, a solar cell and a dial. The solar cell is disposed almost vertically to a solar cell positioning portion provided in the casing ring, and the solar cell has a slender strip shape formed on a flexible substrate. Consequently, the solar cell is not disposed in the timepiece movement, and it is only necessary to change the casing ring as an external component even when a panel cover diameter is changed. Further, a solar cell can be coiled to match the size of the casing ring when it is incorporated in the casing ring, so that a common solar cell can be used despite a change in the panel cover diameter of the timepiece.

Abstract: A method and system for accurate timing in a low current system useful in fuzing applications generates a first count of oscillations of an oscillator of unknown frequency during a first period of unknown duration. A second count of oscillations of the oscillator is generated during a second period of a known duration. The duration of the first period is calculated based on the first count and the second count. A solid-state, thin-film battery is able to be used by virtue of low-current characteristics of the system, enabling extended shelf life for fuzing systems.

Abstract: A watch design that has a movable case that keeps the face of the watch visible regardless of the position of the wrist. In this way, a user can quickly see the watch face in the proper orientation so that the time can be quickly and correctly determined. There are several ways to accomplish this. The case can be mounted on a turntable that rotates on the y-axis. A frame containing the watch mechanism and display is hinged on said turntable and rotated vertically upon the x-axis described by the hinge-mounted frame mounted on said frame. Another embodiment uses a gimbaled point on which the face is free to rotate, much like a compass. In this embodiment, the watch case is weighted to that the face always moves to a readable position. Finally, the watch may include displays mounted in the link of a watchband.
