https://en.wikipedia.org/wiki/Escapement

"escapement: A mechanism in a clock or watch that alternately checks and releases the train by a fixed amount and transmits a periodic impulse from the spring or weight to the balance wheel or pendulum

usage examples:
– a lever escapement
– In 1730 Harrison visited London, taking with him his gridiron pendulum and the grasshopper escapement which he had developed, and there he learnt exactly what was required to win the longitude prize.
– In general, any lantern clock with a balance wheel has had its escapement restored.
– Because they have no gears or escapements to disturb their regular frequency, quartz clocks are extremely accurate and have become the dominant timekeeping technology." [Oxforddictionaries.com]

... in light of the context, which is a list of marks for particular courses, I was looking for something more like a noun. In this particular case:
Uuurwerktechniek > Watch & clock techniques/technology
Gangen & regelorganen > ?? (but the latter refer to control units of some kind)
Rader & slagwerken > Wheelwork & clock striking work (I think)

GWIT:

gang [8] = motion, movement (beweging van een werkstuk)

another option for "gang" would also be speed/velocity

(regelorgaan = control device)
