Product Details

SKU Code: A-17

The A-17 Automatic is a faithful recreation of the classic U.S. Korean War-era military watch (1950–1953). While visually almost identical to the original field watches worn by American troops, this modern version has been upgraded with a 24-jewel automatic self-winding movement and a shatter- and scratch-resistant box sapphire crystal. The sapphire not only maintains the vintage look of plexiglass but also offers vastly superior durability, water resistance, and clarity. The movement can also be hand-wound, preserving the traditional feel of the original design.

This model sits between its two historical companions: the A-11 (based on the WWII USAAF pilot’s watch) and the GG-W-113 (based on the Vietnam-era issue watch of the 1960s–70s). Together, they form a trilogy of faithfully reproduced U.S. military classics.

The A-17 features a heavy-duty 316L stainless steel satin-finish case, a sweep second hand with hacking function, black dial with luminous hands and markers (Luminova), and a robust screw-down caseback. It’s designed for durability and night-time readability, making it as functional today as it was in the 1950s.

Why Sapphire Crystal?

Sapphire is the gold standard for watch crystals. Unlike mineral glass, which is prone to scratches and cracking, synthetic sapphire is exceptionally strong, scratch-resistant, and shatter-resistant. These qualities make it ideal for military personnel, police officers, security staff, and outdoor enthusiasts—groups that account for over 70% of our customers.

After manufacture, sapphire glass is heat-treated to remove internal stresses, then cut and coated with two layers of anti-reflective treatment. The result is a crystal that retains the vintage look of plexiglass while offering modern-day durability. It’s no coincidence that sapphire is now also used on the latest iPhones.

While sapphire adds cost, it dramatically increases performance and longevity—making it the preferred choice for demanding users and serious watch collectors alike.
