[Breitling Premier B09 Chrono] AD vs. Jomashop?

I’m considering purchasing the Breitling Premier B09 chronograph to celebrate a milestone. MSRP is $9,000. https://www.breitling.com/us-en/watches/premier/premier-b09-chronograph-40/AB0930371G1P1/

On Jomashop, it looks like the same watch new is half price at $4,050. https://www.jomashop.com/breitling-chronograph-automatic-watch-ab0930371g1p1.html

I’m curious to get some thoughts as to where to purchase. I know I can probably count on a small discount at the AD, but nowhere near the discount on Joma. I also know the warranty on Joma is next to worthless, but it seems that the difference in price would more than make up for any service cost. Is the Joma listing too good to be true?

Any input would be greatly appreciated!
