White Gold Daytona in UK for SS Daytona

[mjh1234mjh]

Im considering a White Gold Daytona, White Face, with dark arabic markers and dark sub dial surrounds, red hands. (pic attached)

I know these are a lot easier to get a discount on than the steel models. RRP is £19,500 in the UK. I have seen new ones for c. £14,500 on the net.

I have a SS V-Serial (March 2009) Black Face Daytona (with new clasp) fully boxed, unnamed warranty card etc.

I also have a Breitling Navitimer World, white face with black croc strap (Aug 2009), boxed, papers etc.

Both in great condition, no scratches etc. I would need to trade in both to buy the WG Daytona.

What do you guys think is a good trade in for my two watches and what discount could I get on the new WG watch? So basically what money do you think I would need to put in?

Im working in £sterling for all you guys not in the UK.

Cheers
