By the 1980s, quartz technology had taken over applications such as kitchen timers, alarm clocks, bank vault time locks, and time fuzes on munitions, from earlier mechanical balance wheel movements, an upheaval known in watchmaking as the quartz crisis. Quartz timepieces have dominated the wristwatch and domestic clock market since the 1980s.
A clockmaker is an artisan who makes and/or repairs clocks. Since almost all clocks are now factory-made, most modern clockmakers only repair clocks. Modern clockmakers may be employed by jewellers, antique shops, and places devoted strictly to repairing clocks and watches.

Reverse motion – a visual effect in which reversing the order of the frames of a film or video makes time appear to run backward; Reverse tape effects – an audio effect in which reversing the direction of an audio recording renders sounds backward; T-symmetry (or time reversal symmetry) – the expected symmetry of physical laws independent ...
Anchor escapement clocks driven by a mainspring required a fusee to even out the force of the mainspring. It is a recoil escapement as mentioned above; the momentum of the pendulum pushes the escape wheel backward during part of the cycle. This causes extra wear to the movement, and applies varying force to the pendulum, causing inaccuracy.
