Five Star Gift Ideas

Since your boyfriend likes watch collecting, here are a few unique gift ideas that he might enjoy:

1. Watch box: A nice watch box can be a great gift for someone who collects watches. It will help him keep his watches organized and protected.

2. Watch winder: If he has automatic watches, a watch winder can be a great gift. These devices keep automatic watches wound and ready to wear.

3. Watchmaking or repair tool kit: If your boyfriend is interested in the technical side of watch collecting, he might really appreciate a watchmaking or repair tool kit. This kit will allow him to take apart and repair his watches on his own.

4. Custom strap: To add a more personal touch, you can have a custom strap made for his favorite watch. It's a great way to show him how much you care about his interests.

5. Watch book: Many collectors enjoy learning about the history and design of watches. A coffee table book on watch collecting or the history of watches would be a great addition to his collection.

Or you can get him a star map with the date when he was born.
