Does this trade make sense?

[rollx10]

I am considering selling two of my watches and getting one gold watch. The deal is sale of my full set 2005 16613 Serti, slate dial submariner + sale of my unworn partial stickered 116613 blue dial submariner. The second watch is rare as it is a 2020 watch with new style green card. I would part ex both for a full set 2008 full gold 16618 Serti dial, champagne submariner. The full gold sub is immaculate with a 2020 Rolex service. I would need to add £8k/$10k cash as well.

I love the Serti dial and this consolidation of 2 to 1 submariner is keeping me up at night.

I also have in the collection the 116610 LV, 126610 LV and a full set 2007 16600 sea dweller.

What do you guys think?

Thanks.
