Need advice! First and second purchase.

Hi everyone I’m in a very blessed position to purchase a watch or two in the next 6-12 months. I’m dead set on a Daytona Congo 126500 and Pepsi on jubilee. I see the market is slowly going down, which watch should I get first and which would most likely take a bigger fall on price. I’d still get the other one down the road just hoping to save a few bucks with the depreciation. Pepsi here is 22,830 usd and daytona is 28,600. Thanks everyone! Current collection is a 126519ln , batgirl and 5712.
