Good evening. I have the opportunity to purchase a new old stock BlancPain Air Command Flyback in stainless with black dial for just shy of 5.5 us. Wondering if this would be a wise financial decision as I understand these BPs don't hold their value. I would also be selling my Baume and Mercier Riveria to further chip away at the cost. May or may not help but would be buying through a large retail establishment in the US and they offer an additional 3 year warranty. Could I get my money back out of this watch near this price if need be?
