·My two pennies' worth would be not to have it serviced quite immediately, but wear it for a good bit daily and notice what it's doing so that when you do have it serviced reasonably soon, you might be able to let you watchmaker know of any particular issues with it that might be bothering you. Of course, no doubt a competent watchmaker should take any watch, discover all problems and return it running perfectly, but I suspect we all like a bit of direction in our lives.
