Ball Engineer M Pioneer 40mm NM9032C-S2C-BK2

REVIVING OUR RAILROAD STANDARDS OF ACCURACY WITH A NEW CALIBER OF EXCELLENCE. The originator, pacesetter, visionary. In 1891, Webb C. Ball created the official railroad standard of accuracy using stricter criteria than the modern COSC. On our 130th anniversary, our legacy of precision becomes even more exacting with our new in-house movement: Chronometer Manufacture Caliber RRM7309-S. Powering the new Engineer M Pioneer, this watchmaking achievement takes BALL’s standards even further with an accuracy range of -2/+5 seconds per day. New technological advancements, highlighted by an ingenious silicon balance spring, withstand magnetic fields up to 2,500 Gauss and deliver superior shock resistance. Even in the dark, its precision is on full display thanks to our revolutionary micro gas lights. Once again, we are forging ahead with belief that excellence always moves forward.   LIMITED EDITION 1000 WEIGHT Approx. 180g MOVEMENT Automatic BALL Manufacture caliber RRM7309-S Chronometer certified COSC 80 hours Power Reserve, 28,800vph SIZE (CASE) Ø 40mm, height 13mm WATER RESISTANCE 100m/330ft ANTI-MAGNETISM 2,500 Gauss MICRO GAS TUBES 51 micro gas tubes on hour, minute and second hands and dial for night reading capability FUNCTIONS Hours, minutes, sweep seconds and magnified date CASE MATERIAL 904L stainless steel Sapphire crystal transparent case back Amortiser® patented anti-shock system CROWN Screwed-in crown CRYSTAL Anti-reflective sapphire crystal DIAL COLOR Black BRACELET 904L stainless steel bracelet LUG WIDTH 20mm LUG TO LUG Approx. 46.6mm
