@Ssunnylee24 makes good points. The sapphire crystal is an upgrade in terms of scratch resistance, but it has more squared off edges that always bugged me. 19mm bands are annoying. Gotta try them both on of course.
Unless you're totally set on on the FOIS, check out lunaroyster.com. I've heard nothing but good things about him as a seller, and has some solid prices on various new with/without box papers, used, and vintage speedies. No FOIS at the moment, but worth keeping an eye on.
