Look for a hard-to-find collectible watch. Personalized items make excellent romantic gifts. However, you need to ensure that the gift matches your husband's preferences and interests. If you notice he likes watches, engrave a custom watch for him. Avoid engraving something generic on the watch such as, "I love you." If you and your husband have a secret joke or a nickname, incorporate this into the message.
Watch your man for clues. Is he looking for something on his own? What does he collect? Sports fans usually like personalized items from their favorite team, but if he already has many items like this, you may want something even better for him like tickets to the Super Bowl.
