Unveiled at BaselWorld 2014 last month is this new version of Rolex’s new Milgauss.

A first in watchmaking, the timepiece boasts the green sapphire crystal introduced on the Milgauss in 2007, along with an electric blue dial and an emblematic lightning-bolt-shaped seconds hand. It also comes in a 40 mm Oyster case, which is crafted from a solid block of corrosion-resistant 904L steel; and features a smooth bezel and is waterproof to a depth of 330 feet.

Pricing and availability was unknown at press time.
