The key is – knowing your groomsmen personally. If they were your friends, or colleagues then most likely you have the slightest idea what their hobbies or interests are. This will help you find the right groomsmen gift that they will appreciate.
If your groomsmen love outdoor sports such as cycling, lawn tennis, or golf, giving them gears for their sports will be much appreciated than more common groomsmen gifts (money clips, flasks, or cufflinks). If your groomsmen were your best college buddies even the simplest personalized beer mugs can be a great groomsmen gift.
If you’re looking for more extravagant gift for your groomsmen (and because you have the budget) you can give your groomsmen personalized signature watches. You can find online wedding stores selling these type of watches. If your groomsmen love adventure, you may want to schedule an out of town adventure. You can go hiking together, or do canoeing and conquer the fiercest rivers.
Giving your groomsmen individual gifts is also a good way of showing your appreciation. You can pick the gift that best suits their personality. This may require longer time to look for the gifts but will surely be appreciated by your groomsmen.
