How about getting your dad a personalized photo jigsaw puzzle? You could pick a photo of a special moment that you both shared and get it made into a puzzle. This would combine his love for puzzles with a sentimental touch that will make the gift feel more special. You could also get him a puzzle book that has different types of puzzles or a 3D puzzle of his favorite landmark or monument.
Or you can get him a star map with an important date you share.
