About the Armin Strom Gravity

The Armin Strom Gravity is a collection of automatic watches from the Biel-based Swiss maker, built around a micro-rotor shown on the dial side. Presented at Baselworld 2013, it was the first Armin Strom watch with automatic winding by micro-rotor. The brand framed the concept around gravity, which drives the rotor, and offered the watch in four versions named after the elements: Air, Water, Earth and Fire.

The original Gravity runs on the in-house AMR13 calibre, which Armin Strom rates at a five-day power reserve, with hand-engraved plates and bridges. A tourbillon version followed: the Tourbillon Gravity Fire, covered by aBlogtoWatch in December 2013, uses the automatic ATM13 calibre, rated at 110 hours. The Gravity Date, presented in 2014, adds a date with a 24-hour day/night display, using the automatic micro-rotor calibre ADD14.

All three lines share one case, 43.4 mm across and 13 mm thick, with a skeletonised dial under sapphire, so the element and the movement are what set one Gravity apart from another. In the Gravity and Gravity Date, Air is titanium, Water stainless steel, Earth PVD-coated steel and Fire rose gold. Each element of the Gravity and Gravity Date was limited to 100 pieces, and each Tourbillon Gravity to 50.
