Early celebation for him

He got his early presents though his birthday not until March! What a coincidence, MIL invites her sisters, brothers and brother in-laws for a couscous that day. We really had a good time and we even had a Galette des Rois for dessert

This year, he's turning 40! Giving me a headache already what to get for him. Any idea what to get for a person that almost have everything?
