If your boyfriend enjoys collecting watches, you could consider gifting him a high-quality watch case to display and organize his collection. Other ideas could include a watch winders to keep his watches fully wound, a new watch strap in his favorite color or style, or a watch repair kit so he can repair and maintain his watches. If your budget allows, you could even consider gifting him a new or limited-edition collector's watch that he has had his eye on.
Or you can get him a star map with the date when he was born.
