Nivada Grenchen Chronomaster Aviator Sea Diver 86001A-BROL

This version of the Nivada Grenchen Chronomaster combines the automatic movement with a classic strap choice. The reference “86001A” designates the self-winding Sellita SW510 BH b caliber, offering the convenience of automatic winding. The “BROL” suffix confirms the watch is fitted with a Brown Oiled Leather strap, which imparts a vintage, slightly rugged character to the timepiece.Like all models in the modern Chronomaster collection, this watch is a tribute to its versatile 1960s namesake. It functions as a comprehensive tool watch, equipped with a chronograph, a tachymeter scale for calculating speed, and a bi-directional rotating bezel with both 60-minute and 12-hour scales for timing or tracking a second time zone. The dial maintains the classic two-register layout with a running seconds and a 30-minute counter that includes a regatta timer.The significance of this reference lies in its specific combination of the practical automatic movement and the aesthetically pleasing brown leather strap. It caters to those who appreciate the ‘set it and forget it’ nature of a self-winding watch while preferring the traditional look and feel of leather over a metal bracelet or rubber strap. The case is 316L stainless steel, and the dial is protected by a modern, scratch-resistant double-domed sapphire crystal.
