M-1 Field
39mm
Description
A field watch for today. The M-1 takes the archetypal field watch of the 20th century and reinvents it with a minimal 904L stainless steel case, hand-applied Globolight™ numerals and our signature dished, one-piece dial. Stripped back to the bare essentials, it combines design purity with Swiss engineering. Built to loyally accompany you on adventures near and far.
Field watches have long been relied on by those on the ground, in the sea or in the air. They are durable tools, built to withstand whatever the day throws at you. The M-1 Field is no different, encompassing everything we’ve learned in a small 39mm package. This is the watch you can take on your travels, whether you’re circumnavigating the world or heading to a business meeting. It is designed to be worn with anything, anywhere and never look out of place.
Powering the M-1 is a manual-wound Sellita movement, known for its reliability in all manner of conditions. Once fully wound, it’ll keep ticking for 42 hours. It’s housed within our satin-brushed case, which looks the part and thanks to its 904L steel, is built to withstand corrosion. Our steel contains higher chromium and nickel content than the industry standard 316L steel, making it far more durable and able to withstand exposure to extreme environments. The domed sapphire crystal meanwhile combines with our signature dished, one-piece dial to create a 3-D look, elevating and updating the military-inspired design.
Elsewhere, a classic railroad minute track runs around the dial’s edge, and large numerals, hands and sub-seconds offer impressive readability in all lights. This is helped by the Super-LumiNova®, which is hand-applied to the hands, markers and crown pip, as well as the track on the sub-dial, making each watch unique. The numerals and Aera logo meanwhile are hand-applied and cut from solid blocks of Globolight. This ensures the watch glows a bright military green in the dark, with the logo emitting a bright white light.
The M1-Field watch comes on an integrated smooth Jet Black Italian leather strap with white stitching and a 904L stainless steel buckle. In addition, you will receive a complimentary Charcoal Grey suede strap. Both straps feature a quick release mechanism for easy switching, as well as our integrated design which forms comfortably around the wrist. We spent three years perfecting the shape of our straps and lugs, purely so they would be comfortable all day long. A handmade black pebble grain Italian leather pouch also accompanies every watch.
