Why are titanium ones so much cheaper?
just an older version, and like i said on the ti bracelets theres not that much difference, some of the later ones on the pro2 TI fetch as much as the steel ones, you have to be quite careful with the ti when screwing in the crown as the strength of the titanium in the crown exceeds the thread on the case, which if cross threaded can cost you £6-700, trust me on this one!
breitling now do a 12 month interest free so go have a look at the ad sometimes its less hassle buying new, especially if you dont know what your looking for!( they will come down about 35% on the price in the window!)
