Nivada Grenchen Chronomaster Aviator Sea Diver 86001A-BLAL

This reference, the 86001A-BLAL, is another variation within the modern Nivada Grenchen Chronomaster Aviator Sea Diver family. Like the 86001A-BRAC, it is an automatic version, as indicated by the “A” in the reference number. The key differentiator for this specific model is identified by “BLAL,” which signifies a black dial (“BL”) and a black leather strap (“AL”).The watch upholds the Chronomaster’s legacy as a multifaceted timepiece designed for various activities. It incorporates a chronograph, a tachymeter scale, a bi-directional rotating bezel with 60-minute and 12-hour markings, and a regatta timer within the 30-minute chronograph sub-dial. This iteration offers a different aesthetic from the bracelet versions, providing a more classic and understated look with its leather strap.The historical context remains the same, as it is a faithful re-edition of the popular 1960s original. The significance lies in its adherence to the vintage design while being equipped with a modern and reliable Swiss automatic movement. The case is stainless steel, and the watch features a double-domed sapphire crystal for enhanced scratch resistance.
