Seiko watch case refinishing recommendations

I have a Seiko SRP-773 with a Roman numeral date wheel. I‘ve had this watch for 10+ years and it shows it’s age. I had considered cutting it loose but have decided to keep it. That being said, I’d like to have the case “cleaned up” a bit. I’d like to find someone that has experience with Seiko‘s because I’d like the the brushed surfaces to retain the factory appearance. Thanks in advance!
