Rolex Datejust 16220 from 1990 with the IBM engraving on the back.
My friend's dad passed away recently, and he asked if I wanted to buy his dad's watch (or help him sell it). It's a 1990 16220 (Silver dial, Engine Turned Bezel, Oyster bracelet) with box/papers.
I feel like I could give him a fair price on that... because there are probably thousands of comps I could compare with :)
What i don't know about is the engravings on the case back.. It has his Dad's name, the IBM logo, then the date November 1990.
It's in ok shape, zero service history (as in.. I know the history: it's never been serviced).
Does this IBM Engraving hurt, or increase the value?
If I buy it, I want to give him a fair price (the money goes to his mom). If we sell it i don't want to go into getting offers blind. What do you think would be a fair price for a basic 16220 w/oyster and a personalized caseback?
