doesn't work/isn't working all of a sudden

[joham]

My watch doesn't work/isn't working all of a sudden.

This sentence is taken from L. G. Alexander's RIGHT WORD WRONG WORD.

My question is whether the phrase 'all of a sudden' goes with both 'doesn't work' and 'isn't working' or just with 'isn't working'.

Many thanks in advance.

Works with both, but present continuous, "isn't working" with "all of a sudden"(now) would be correct.
