No: verbs cannot function as object complements.
This is a catenative construction in which "watch" is a catenative verb and the subordinate infinitival clause "boil slowly" is its catenative complement.
Note that the noun phrase "the pot" is the syntactic object of "watch" and the understood subject of the subordinate clause. The natural interpretation of "slowly" is that it modifies "boil".
The term 'catenative' comes from the Latin word for "chain, for the construction is repeatable in a way that enables us to form a chain of verbs in which all but the last have a non-finite complement. In your example, the chain is short -- just two verbs separated by the NP "the pot".
