Making use of clock parts to build wrist watches offers one an outlet for private expression, a chance making a personal declaration. The parts of a clock are basically standard, implying that generally they operate no matter exactly how they are blended and also matched, as long as they are sized effectively. For this reason the clockmaker is quite free to let his creative imagination run with design and creative thinking.
Of course, clock parts have to be framed in something to earn them a device. This establishes the overall measurements of the wrist watch as well as necessary figures out the appropriate sizing for the parts. You might have an existing case, probably retrofitted from falling into disuse, or you could have the propensity for designing as well as building instances from square one.
In some cases the instance is so stylistically unique or naturally purposeful as an antique that it alone reveals adequate originality. In such instances you don't desire the clock hands and dial to overwhelm the declaration, yet to enhance it or bring it much more into emphasis. It could also make good sense to select the relative modesty of a preassembled clock insert or "fit-up" as opposed to construct from parts..
