Pretty much any time you send an Omega in to their service department, they will swap out anything that looks remotely worn and return your watch lightly repolished and in perfect condition. I've had a couple of POs done and it's honestly like getting a new watch back. You'll even get all the replaced bits (cogs, gears, watch springs, hands etc) back in a plastic bag, along with a list of work done. Sure, they're more expensive than a local watchmaker, but all the replacement parts are included in the cost of the service (within reason). Totally worth it in my opinion.
