Engagement ring equivalent for men

I really want to get my fiancé a meaningful gift—something that feels just as special to him as receiving an engagement ring feels for women. He’s mentioned that he’d like an engagement ring too, so I’m torn between a couple of ideas.

Should I get him a watch (he is obsessed w watches) with our engagement date engraved or an actual ring for him to wear until our wedding (which is two years away)? I’d love to hear your thoughts or suggestions!
