A perfect anniversary gift for your boyfriend who likes watch collecting could be a new, unique watch that he does not already have in his collection. Here are a few suggestions:
1. Vintage watch: If your boyfriend likes vintage watches, you can find an antique store or an online retailer that specializes in vintage watches. Pick one that reflects his style and is a unique addition to his collection.
2. Smartwatch: If your boyfriend does not have a smartwatch yet, this could be a great addition to his collection. It will not only serve its purpose but also will add a more modern look to his collection.
3. Limited edition watch: Look to see if any famous watch brands have any limited-edition watches that have recently been released. This can be a good investment and a special present that he will treasure forever.
4. Watch winder: A watch winder is an ideal gift for any watch collector. This device will rotate the watch regularly to ensure that the automatic watches function correctly and maintain accuracy.
5. Watch strap: You can purchase watch straps in different colors, patterns, and styles. You can also consider getting a custom-made one with his initials, making the strap personal and unique.
Or you can get him a star map with the date of your anniversary.
