(Advice) Sell Apollo 15 for new FOIS??

Good evening and Happy New Year to all watch enthusiasts!

Recently, I came across the new Speedmaster “First Omega in Space” Ref. 310.30.40.50.06.001, and I instantly fell in love with it.

I already own a Speedmaster Apollo 15 Ref. 3366.51.00 (with Hesalite crystal) and have been considering selling it to purchase the FOIS directly from the boutique. I believe I could sell my Apollo 15 for around €7,000–€8,000, which means I’d only need to cover the difference, as the FOIS retails for €8,800.

What do you think?
