Alongside the link stainless steel chronograph Breitling has introduced the link "Night Mission" version with the same specs just a black ceramic bezel and case with a black or yellow dial the crown and pushers are titanium!. MSRP of the Night link Mission Chronograph is 9300.
For link me, the 5170, with its high estimate of $80,000, presents more value than the 5070P (high estimate of $120,000, though it'll probably sell for more like $200,000). But if you love the link 5070, I'm not going to link tell you you're wrong. Winner: 5170
