Military aviator watches are timepieces specifically designed to meet the needs of pilots and aircrew, offering durability, legibility, and functionality in the demanding conditions of flight. These watches have a long history, evolving from early military aviation to modern times, and they serve as reliable instruments for timing and navigation. We intermittently receive watches at various clearance sales from various different brands, but the most common watches which we come across are generally MWC or sometimes Pulsar, Citizen and Seiko to some extent with focused here on MWC but what applies to MWC will generally apply to the other brands as well but as far as we are aware only MWC has such a high range of science variations going from the small 40 mm models up to the large 46 mm models.
