http://www.thewatchbox.com In 2007, Hublot's Big Bang Mag Bang limited edition was a landmark volley in the lightweight watch wars. At 70 grams, this featherweight is almost two ounces lighter than the "barely-there" Audemars Piguet Royal Oak Offshore "Bumblebee" that set the standard for lithe sports watches. Hublot's 250-piece limited edition Mag Bang incorporates exotic magnesium alloy for the outer case, lugs, and bezel. Magnesium is extraordinarily difficult to work, finish, and preserve against corrosion; it burns white-hot if ignited. But get it right (Hublot teamed with an Italian specialist that supplies parts to Ferrari), and the result is sublime. Hublot advances its cause with an inner case crafted of titanium. Moreover, the caliber HUB44 is enhanced with titanium chronograph base plate, bridge and screws. The entire movement remains tough-as-nails but sees its mass slashed from 45 grams to nearly 20. In the tradition of the Nyon-based watchmaker, a natural rubber strap complements the exotic case. The black bands supple wrist feel is the perfect touch to complete an ergonomic experience best compared to a feather halo for your forearm. This Hublot Big Bang Mag Bang, one of the most sought and coveted of Hublot Big Bang limited editions, is available from thewatchbox.com in extraordinary condition. If you missed the boat in 2007, jump aboard, because this luxury liner doesn't make many port calls. Video and content by Tim Mosso.
