I have two Eco-drive skyhawks, Both U650's one in stainless and the other in titanium. They have the basic wear and tear of a 15 year old watch, both work perfectly fine other than they look well worn. I am looking to get them looking like new or just better than what they are now. Looking for any suggestions/recommendation on where to send them?

Hurley roberts to work them over topped out over $530 for both (ouch). Other options?
