Armin Strom, a modern watch brand for the modern watch-fascinated man, has just released the new Tourbillon Gravity Collection at Baselworld this year. The new collection constitutes four watches, one of which (the Gravity Fire) has already been released earlier this year. The other three watches, the Gravity Air, Gravity Earth, and the Gravity Water are all what I would consider to be sport-tourbillons. These new editions to the lineup come in three metals, none of which are precious, stainless steel, titanium, and ss with a PVD black coating.
All the watches have a diameter of about 43 millimeters (a nice size for watches of this style) and a thickness of 13 millimeters (wears comfortably and looks good on the wrist).
They all come with a standard Alligator strap (color varies depending on watch model) and a sporty, durable rubber strap. Get them while you can, as they are limited to 50 pieces per model.
