The Grand CARRERA Calibre 36 RS2 Caliper Chronograph Ti2 is resolutely virile and ultra high-tech. Inside beats the COSC-certified TAG Heuer Calibre 36 RS Automatic Chronograph movement with 2 Rotating Systems, visible through a handsome caseback in smoked sapphire crystal.The jet black chassis and bodywork (43mm case, fine-brushed and polished bezel, and fine-brushed and faceted case) are made of grade 2 Titanium (Ti2), an ultra-resistant and biocompatible pure metal twice as light as steel. The oversize crown at 10 o’clock — also in Ti2 — activates the Caliper Rotating Scale, enabling magnified 10X reading to 1/10th of a second. Other top-end features include a linear permanent second counter at 9 o’clock and a black rubber bracelet with black titanium end piece and folding clasp that grips the wrist the way a GT car hugs the road.
