Submarine Watch Ocean Green Limited Edition 524.481

The Watch

The story of Airain begins at the dawn of aviation, when watches were essential tools for navigation and aerial coordination. Inspired by that heritage, the brand crafts robust, reliable timepieces capable of withstanding the most extreme conditions while retaining timeless elegance. Designed for modern adventurers - whether aviation enthusiasts, explorers, or simply those seeking a refined yet functional accessory - every Airain creation reflects a meticulous attention to detail, from design through assembly. This stunning Ocean Green watch belongs to the Sous-Marine collection. Produced as a limited edition and born from the CoLAB initiative, it is sure to captivate lovers of marine adventure. It features a round case crafted from 316L stainless steel, measuring 37.50 mm in diameter, 48.20 mm from lug to lug, and 11 mm in thickness - dimensions perfectly suited to men's wrists. The case features a silver tone with a brushed finish that complements its design beautifully. A domed sapphire crystal 2.92 mm thick sits atop the case, effectively shielding the dial from scratches that could mar its aesthetics, while its anti-reflective treatment ensures clear legibility of the time indicators. The watch also features a unidirectional knurled bezel with a minute track, fully coated in black PVD and equipped with a SuperLuminova marker that glows in the dark. The Parmentier crown at 3 o'clock lets you adjust the hours, minutes, and date to your liking. Finally, the screwed case back provides a water resistance of 20 ATM and features an engraved diver motif.

The Dial

Dressed in green, this dial enhances the beauty of this timepiece. Designed for exceptional timekeeping legibility, its outer edge is bordered by a minute track running alongside rectangular indices. These are paired with Arabic numerals and baton indices marking the hours. Treated with old radium lume - as are the three central hands - these markers ensure smooth, effortless time reading. The hands display the hours, minutes, and seconds, assisted by a date window that keeps you on schedule. The brand completes the dial by signing its creation with its name at 12 o'clock.

The Movement

At the heart of this watch beats a Swiss automatic movement - specifically the AM5 caliber, which reliably drives the hands and date window. Equipped with 24 jewels to minimize friction, it operates at a frequency of 28,800 vibrations per hour. This movement delivers a power reserve of 68 hours and features a tungsten rotor and a stop-seconds device.

The Strap

Airain presents this beautiful watch with two interchangeable straps for ultimate style versatility. Both equally charming, they offer outstanding comfort and measure 20 mm in width at the lug.

The first FKM rubber strap is ideal for adding a pop of color to your wrist. In a vibrant green hue, it features perforations that add to its appeal. It fastens with a silver pin buckle measuring 18 mm in width.

The second strap, in a silver tone, is crafted from 316L stainless steel. Fixoflex in construction, it consists of several brushed links that are easily removable, allowing you to size it to your wrist. It is expandable and therefore clasp-free.

Water Resistance

With a water resistance of 200 meters - 20 ATM in proper watchmaking language - this watch is built for shallow-water diving. It handles shower water, bath water, and open-water or pool immersion for casual, non-professional dives (including freediving) without breaking a sweat. For professional scuba diving with tanks, our Ocarat watch team has handpicked a selection of 30 ATM models available in our catalog - just use the search function on our site to find them. One last reminder before we leave you to it: never operate the pushers or the crown while underwater!
