How about a nice traditional dress shirt or tie from his favorite brand or store? You can make it even more special by having it monogrammed with his initials. Alternatively, you could make a gift basket of traditional fashion items such as cufflinks, collar stays, pocket squares and a nice dress watch. Another idea is to check out any high-end men's clothing stores or boutiques in your area that might offer gift vouchers or gift cards that he can use to purchase something he really wants.
Or you can get him a star map with the date of your first kiss.
