Current value of Rolex 1680 red Sub please?

[gmt 16750]

In the current climate what would one reasonably expect to get for a 1971 (306… serial).
Watch is in very, very good order - dial, hands & bezel pearl are flawless & match perfectly with a creamy, light beige colour).
Watch is just back from William Rice after a service so had a 23 month warranty.
Sorry no pics as yet.
