Like this one. The limited edition (1999 piece) Ball Storm Chaser.
Released as a tribute to storm chasers, the caseback has an engraving of Josh Wurman’s Doppler on Wheels. He was the first man to mount a weather radar on his truck to analyse and understand the structure of these phenomena apparently.
The case is stainless steel black PVD and measures 43mm. It has an AR-coated sapphire crystal and is water resistant to 100 meters.
Movement is the Swiss automatic ETA caliber Valjoux 7750 with 25 jewels, 28,800 vph and a power reserve of 42 hours.
The black dial features 66 micro-tubes of tritium gas.
