For your grandpa who loves collecting watches, you can consider the following gift ideas:
1. A watch case: A watch case will not only help your grandpa store his watches safely but also make it easier for him to pick the watch he wants to wear without any hassle.
2. A watch winder: For the automatic watches that need to be kept running, a watch winder is the perfect device. Make sure that it is compatible with his watch.
3. A watch repair kit: If your grandpa loves collecting vintage watches or complicated chronographs, he might enjoy tinkering with them to perform minor repairs. You can gift him a good quality watch repair kit.
4. A watch with sentimental value: If you can afford it, you could gift your grandpa a watch that has some special meaning or sentiment attached to it.
5. Watch-related books: For a watch enthusiast, books about watches are a treasure trove of information. Look for books that talk about vintage watches, watchmaking, or watch history.
Or you can get him a star map with an important date you share.
