Return of a Field Classic

The OW MK-102 returns from the archives and brings a lost military history to the wrist: inspired by the 1969 K-101, which was once made for the 2nd Infantry Division of the US Army, the watch bears the distinctive Indian Head emblem as a visible sign of courage and perseverance. Anyone who winds the model immediately feels the connection to an era when reliability and robustness decided life and duty — a revival that shows respect for the original while meeting modern expectations.

Design with a Historical Heart

The case made of brushed 316L stainless steel measures 39.5 mm in diameter and was proportionally designed to preserve the robust appearance of the field watch prototype while providing contemporary wearing comfort. The reduced height of about 12.5 mm and the 48 mm lug-to-lug distance ensure a confident fit on the wrist; the screw-down crown, screw-down case back, and rotating steel bezel emphasize the functional, military character of the watch.

Technology that Connects

Inside works the Soprod P024 caliber specially tuned for OW: an automatic movement with 4 Hz, hacking seconds, quick date adjustment, and approximately 38 hours of power reserve, equipped with an OW rotor engraving and specially made screws. These manufacture details show that the reissue not only recalls the original externally but is mechanically refined to meet today’s demands for precision and serviceability.

Operational Suitability and Legibility

Designed for use, the MK-102 offers water resistance of 300 m / 30 ATM and a sapphire crystal with anti-reflective coating that ensures clear legibility under all lighting conditions. Hands and indices are coated with Super-LumiNova, so the watch reliably performs its duty even in the dark and underwater — features that in practice are much more than technical data: they are the promise of reliability.

Equipment and Wearing Options

The MK-102 comes standard on a military-robust gray RAF strap (20 mm) with a brushed pin buckle; those who prefer a different feel can optionally choose the finely linked M-Heritage Milanese bracelet. These strap options allow the watch to quickly transform from a military-functional look to a more elegant appearance without blurring the model’s core idea — the versatility remains intact.

Limited Edition, Origin, and Presentation

The first 56 pieces feature numbered crowns; thereafter, the famous OW propeller monogram will appear on the winding rotors; each watch is handmade and regulated in the Swiss Jura region, emphasizing the close connection between historical heritage and regional watchmaking art. Equipped with a three-year warranty, the MK-102 is not only a collector’s item but a wearable piece of history that combines everyday usability and authenticity.

Conclusion: A Strong Presence with Substance

The OW MK-102 is more than a reissue: it is a critical reassessment of a field classic that combines historical identity with modern manufacturing standards. Anyone looking for a watch that breathes history, functions strictly in use, and is mechanically sophisticated will find a convincing offer in this limited rebirth — robust, precise, and with genuine character.
