A great gift for your grandpa would be a Hermès tie. Hermès is known for its high-quality silk ties, and they come in a wide range of colors and patterns. Alternatively, you could consider a Hermès cashmere scarf, which is also known for its luxury and comfort. If your grandpa enjoys reading, you could get him a book about the history and philosophy of the Hermès brand. Another option could be a Hermès leather wallet or a leather-bound notebook. These gifts are not only thoughtful but also practical and useful.
Or you can get him a star map with an important date you share.
