I have two Omega, both of which are "previously enjoyed" pieces, and I agree...that's a fair price. Seeing as how the movement needs cleaning, It wouldn't hurt to ask if the seller would consider knocking the price down a little to compensate for the cleaning needed, but even if the seller won't do it, it's still a good price!
BTW...except for that tiny piece of dirt on the "1", the dial is in great shape!
