Saw this advertisement which states that the polymer version of Unobtanium is now in commercial use. There is also an "O Matter" construction technique.

Oakley D3 Watch The Oakley D3?race day performance for small wrists. Description:
Oakley designed the D3 Watch with a smaller face and band for endurance racers, marathon runners, and triathletes who want big-time functionality without the bulk. Oakley designed this watch with a continuous *Unobtainium* band for comfort and with a proprietary software engine that logs 45 separate runs and stores 90 lap times, lap numbers, split times, and the fastest lap time. But this isn't just a training watch. The D3 can take all the knocks of race day thanks to its scratch-resistant crystal and durable O Matter construction, which is shock-resistant and ensures the watch is waterproof to 100 meters.
