Watch part established to hold male South Africans? (10)

I believe the answer is:

escapement

I'm a little stuck... Click here to teach me more about this clue!

'watch part' is the definition.
'escapement' can be an answer for 'part' (I have seen 'part of watch' mean 'escapement' so perhaps 'part' could also mean 'escapement'). I am unsure of the 'watch' bit.

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for escapement that I've seen before include "One-time flight" , "Part of watch mechanism" , "piano piece" , "Part of A Clockwork" , "Clock or watch mechanism" .)

I've seen this clue in The Times.
