Type 20 421.436S Watch

The Watch

Airain is a watchmaking brand that draws inspiration from the past while embracing modern technology. Its creations are defined by a vintage design evoking the classic military watches of the 20th century, combining practical features with long-term precision. Airain blends vintage style with modern performance, offering sumptuous, high-quality pieces for watch enthusiasts. The brand draws on the heritage of pilot and dive timepieces to deliver robust, functional watches built to withstand the most demanding environments. The Type 20 watch presented here stays true to the design and specifications of the original Type 20 from the 1950s. It features a round case crafted entirely in stainless steel, measuring 39.50 mm in diameter, 47.75 mm lug-to-lug, and 10.85 mm in thickness - dimensions that suit all men's wrists perfectly. The case has a silver tone with brushed and polished finishes for a striking look. It features a bidirectional knurled bezel with a "Old Radium" Grade X1 SuperLuminova marker and a graduated visual countdown. The domed sapphire crystal protects the dial from shocks and scratches while its anti-reflective treatment ensures clear readability of the time indicators. The chronograph and other functions are operated via the crown and two pushers positioned at 2, 3, and 4 o'clock. Finally, the screwed caseback ensures water resistance of 5 ATM, or 50 meters.

The Dial

The dial of this watch reveals a black background that adds to its charm. Its outer edge features a minute track with fine graduations and Arabic numerals for easy time reading. These surround luminescent beige Arabic numeral indices for precise hour reading. Both the indices and the three hands above them are coated with a SuperLuminova treatment for excellent legibility even in dark conditions. The hands display the hours and minutes, while the slim seconds hand tracks the chronograph seconds. The dial also features two sub-dials at 3 and 9 o'clock, indicating 30-minute and small seconds counts. Finally, the brand name is printed at 12 o'clock as a signature.

The Movement

This model is powered by a Swiss-made manual-winding mechanical movement - specifically the AM2 caliber from manufacture AMT in La Chaux-de-Fonds, featuring a flyback complication. It reliably drives the analog display day after day. The movement includes 23 jewels and delivers a power reserve of 63 hours.

The Strap

This timepiece comes with a strap crafted in genuine suede leather in a rich cognac color. At the lugs, two beige stitching lines add an elegant finishing touch to its design. The strap features a textured surface for optimal comfort and fastens with an engraved tang buckle, with a lug width of 20 mm.

Water Resistance

With a water resistance of 50 meters, or 5 ATM in standard watchmaking terms, this timepiece can handle splashes - but isn't built for prolonged water exposure. An occasional shower is fine, though keeping it away from H2O found in baths, pools, and the sea is the best way to preserve the movement's quality and precision. In short: no swimming, no diving, and no extended contact or immersion.
