about the passive

Hello, everyone!

I have a question about the passive. Could you take a look at the sentence below?

A watch was bought for me by him.

Can I omit the prepostion 'for' as in 'The present was given (to) me by them.'? Could I say like the below?

A watch was bought me by him.


Many thanks in advance!

No. Also, using a passive sentence to express this sounds very awkward. I'd just say, "He bought a watch for me."

Thank you very much for your kind and detailed comment.
