Hamilton H10 after 6.5 years service recommendation

I bought this watch new 6.5 years ago. Ive worn it every day, save 5 minutes in the shower, for 4 years and quite a lot after that as well. Ive been thinking about having it routinely serviced but the stats (timegrapher app on the phone) seem ok? What do you recommend? Anything I should know about the H10 etc?

Thank you for your opinions.
