FS: 1968 Waltham ABU-9/A Aircraft dash clock

Waltham aircraft clock ABU-9/A mechanical 8 days aircraft clock made according to MIL-C-27289 spec. Marked "8 DAYS" and ABU-9/A (in black on black) on dial. Low #1203 s/n#.

Data plate on back reads:

98429-W33-7590-10A

SER. NO. 1203

CLOCK, AIRCRAFT, MECHANICAL. ABU-9/A

CONTRACT NO DAAA25-68-C-0807

U.S.

Clock sets, winds, and runs to about 30-45 sec/day accuracy but chrono is frozen and does NOT work. I bought this as a fixer-upper but never got around to servicing and mounting it for desk use. This model would be electrically illuminated in red, but I have not hooked it up to electrical to test the illumination. No information on the type(s) of aircraft this model was used in, though some casual research suggested these were often used helicopters.

The winder knob at 8 o'clock has had a "bite" ground out of it, perhaps a modification to create a notch for easier grip when pulling to set or as an expedient repair to allow a shorter screw to be used to attach the knob. Glass crystal has proper dual-coat AR coating intact.

Sold as is.

$150 shipped in CONUS by Paypal. Shipped elsewhere at cost. Inquire by PM or email to watches@ryanrooney.com.
