Nivada Grenchen Chronomaster Aviator Sea Diver 86001A-BRAC

A close relative of the 86007M-BRAC, the Nivada Grenchen Chronomaster Aviator Sea Diver 86001A-BRAC is the automatic-winding counterpart. It shares the same multi-purpose design philosophy, combining the functionalities of a pilot’s, diver’s, and racing chronograph. The “A” in the reference number designates its automatic movement. The watch maintains the vintage-inspired aesthetic and robust “tool watch” character of the Chronomaster line.Like the manual-wind version, the 86001A-BRAC features a bi-directional rotating bezel with both 60-minute and 12-hour scales, a tachymeter, and a chronograph with a 30-minute counter that includes a five-minute regatta timer. This reference also comes with a stainless steel “beads-of-rice” bracelet. The primary distinction from the 86007M-BRAC is its self-winding mechanical movement, which appeals to those who prefer the convenience of an automatic watch.The case is constructed from stainless steel, and a double-domed sapphire crystal protects the dial, ensuring durability. Due to the automatic movement’s rotor, the case height of the 86001A-BRAC is slightly greater than that of the manual-wind version, a common characteristic in watches with automatic movements compared to their manual-wind counterparts.
