The quintessential "hack" watch of World War Two; "the watch that won the war."

Although originally designed to be issued to the Army Air Forces with specifications dating to 1941 and 1942, this watch saw use with troops all across the world to include the Royal Canadian Air Force. Designed to be used for synchronization via "hacking," the second hand will stop when the crown is extended, allowing for time to be adjusted and set to the second. The RCAF ordered 5,000 of these in 1942 to be issued to pilots, navigators, bombardiers, and other personnel requiring a precision watch.

The hacking function allowed synchronization for missions, artillery, and attacks which kept airmen and soldiers on target and on time. 

Manufactured by Waltham under parts number 10616, the "Watch, Navigation Hack" became ubiquitously referred to by its specification "A-11." The A-11 is one of the most recognizable watches in the world, and we have spared no expense in replicating them down to the last detail. The RCAF A-11's featured reversed dial colors, fire-blued hands, and a waterproof Keystone case.

Ours feature the following details:

• Marine grade nickel-plated brass cases, just as originals were produced.

• 24-jewel Miyota 9039 movements with hacking seconds, modified for hand-wound use only.

• Non-reflective vintage style textured dial paint.

• 5ATM water resistance.

• Fire-blued stainless-steel hands.

• Fully period correct packaging.

• Limited two-year warranty.

• Period correct sized down to the last measurement - 31mm (32mm with crown) Keystone style waterproof cases, 16mm lug to lug width, and 25mm dials.
