Originally supplying service watches under MOD contracts, Precista built a reputation for function-first design, rugged build quality, and timeless legibility. Revived by Timefactors in more recent years, the brand continues to honour its tool-watch roots by recreating historically inspired military models with modern materials and dependable mechanical movements.

What's on offer

We are delighted to offer for sale this very handsome Precista PRS-45, a striking homage to the legendary Type 20 flyback chronographs worn by French military pilots in the mid-20th century. (Namely the mythical Blancpain Air Command). 

This version is powered by the reliable Seiko VK64 mecaquartz movement, offering quartz precision with a satisfying mechanical chronograph feel. The matte black dial is clean and legible, featuring luminous Arabic numerals, vintage-style syringe hands, and a bold yellow 24-hour indicator at 3 o’clock. Housed in a brushed stainless steel case and fitted to a beads-of-rice bracelet, it’s a robust, aviation-inspired timepiece with vintage charm and modern convenience.

This watch is in exceptional condition, showing almost no signs of wear. The case remains sharp with its original finish intact, and the crystal is clear and free from scratches. Powered by a dependable mechanical movement, the PRS-45 is as functional as it is timeless.

The watch os offered for sale with its original box and papers in superb preowned condition. This is a great purchase and a fantastic addition to any collection. 

Whether you're a collector of military-style timepieces or seeking a durable everyday watch, the PRS-45 Aerotimer delivers both heritage and performance in equal measure.
