I'm getting my FI this watch from Victorinox. He's not a jewelry/dress up guy either. But he's also super interested in automatic watches and being able to see the movement (this watch has a clear plate in the back so you can see the gears and stuff).
What hobbies is your FI interested in? Maybe you can find him something small but high quality that can be engraved with a short message? I considered getting my FI some sort of special woodworking tool or a new lens for his camera but the watch seemed more appropriate for a wedding day gift.
Fi and I decided not to really get each other gifts. However, we did decide to splurge and get custom wedding bands made. We mutually decided that the rings would be a perfect gift to each other for our wedding. He bought mine. I bought his. They were made to match. They are different but beautiful and it helps that no one had any say at all in their design just because they were footing the bill for the rings. They are completely "ours" and I'm so happy it's that way.
It may not be the typical way to do things, but we're super happy and excited about our "gifts". We will wear them for the rest of our lives as a symbol of our love and commitment to each other, so we could really think of no better gift to give.
"They say there's no such place... as Paradise. Even if you search to the ends of the Earth, there's nothing there. No matter how far you walk, it's always the same road. It just goes on and on. But, in spite of that... Why am I so driven to find it? A voice calls to me... It says, 'Search for Paradise.' " - Kiba, Wolf's Rain
