1964 Tudor 7928 opinion

[Leed123]

Hello,

I have a 64 tudor sub 7928. Serviced only three months ago. Has a 69 rivet bracelet fitted which is in pretty good shape for age. Can confirm it have the 390 movement. Also has a very nice plexi super dome fitted. Had a light polish when serviced. Some light corrosion on the hands. I would like to sell it as I purchased a NOS Heuer Autavia 11063 GMT in mint condition.

The problem I have is I haven't a clue what to sell the 7928 for?
I live in the UK so would have to be UK prices. What is the market range?

It's not the pointed crown type. Serial number is 400 series. Bezel is original and mint. No box or papers.

Ideally want to buy a Heuer Carrera 510.523 with the cash....

Your thoughts.

Thanks lee
