Seiko dive watches?

Got a buddy who wants to sell his Seiko White Knight and doesn't know what a fair price to ask for it. Admittedly I know nothing about that model so I told him I'd check eBay and ask on the forum. Anybody have a ballpark of what a nice condition model will go for? If it was an 007/009 or a Monster I could answer from first hand experience, but I've only just held a White Knight once for a few minutes so I have no clue. Thanks!

What did you find out?

Looks like they sell for under $200 pre-owned. Considering they can be found in the $250 to $300 range new that's pretty damn good resale value. Same with the Monsters - bought mine for $170, sold the head only for $115 a little more than 2 years later.

this is on the bay for 105 buy it now

When I bought my Orange Knight (not new) I paid $175. You should buy it. Great watch.

It isn't for me. He wanted to list it and didn't want to be out of the ballpark on price.
