How about gifting your friend a personalized watch box, which can hold several watches in one place and help keep them organized? You could consider getting it engraved with their names and wedding date to add a special touch. Alternatively, you could gift a unique or limited edition watch that they can add to their collection. If you know the brand or style of their favorite watch, you could also look for a complementary accessory, such as a watch strap or cufflinks, that they can wear on their big day.
Or you can get her/him a star map with the date of the wedding.
