Just read today (although the news has apparently been out for a while) that Lum Tec are going to start producing Cobalt-chrome cases for some of their M series watches in 2013.
Cobalt-chrome is another great choice for watch cases as it's almost as hard as tungsten-carbide (which I absolutely LOVE as a watch/jewellery material) but less brittle, lighter in weight (although still heavier than steel), and a much whiter colour. It's apparently slightly easier to machine as well, hopefully resulting in slightly crisper lines which is something that tungsten carbide cases can lack. There are only some concept pictures out there at the moment, and to be fair they look exactly like every other M series Lum Tec watch, but the case material is the real draw.
I've said it before, but if a (relatively) small company like Lum Tec can experiment and produce very nice quality watches in more exotic materials, then why can't Breitling? Cobalt-chrome and tungsten carbide would both be ideal for polished watches such as the Navitimer as they just don't scratch. Hell, Breitling could put Cape Cod out of business overnight if they just TRIED it!
