OW MK-102 (Numbered Edition)

The M-Series Heritage Collection is a commemorative reimagining of custom field and pilot watches made by Ollech & Wajs for various branches of the U.S. Military in the late 1960s and early 70s. They were purchased by serving personnel deployed across Southeast Asia, as well as by returning veterans who valued OW watches for their reliability, robustness, and extreme water resistance. Surviving examples are extremely scarce and highly sought after by collectors of vintage OWZ.

The re-issued watches preserve both the spirit and legacy of OW’s deep military heritage. While each model is allegiant to the original, it has been thoughtfully re-engineered to meet contemporary OW standards for precision, durability, and design.
