I have two perfect steel-cased Marathon navigator watches for sale. One has original quartz movement and the other has a hacking Bulova automatic movement custom installed. They were issued to USAF pilots in 1990. Both are in perfect condition with no flaws. The only reason I am selling them is to gather funds for Sinn EZM1.
1. Marathon Navigator (Original Quartz)
1990 issue. Quartz movement, original hesalite crystal, and new battery. Bezel is clean and clicks well. Original strap included. Asking $350 USD.
2. Marathon Navigator (Automatic Movement)
1990 issue. Original hesalite crystal. 17 jewel ETA automatic movement (hack feature, manually windable) installed by Certified Master Watchmaker. Bezel is clean and clicks well. Original strap included. Asking $440 USD.
Offered with three day inspection period. Price includes registered airmail delivery to anywhere in the world. EMS express airmail option is available at $10 more. Please read my review for more information (the one pictured in my review was sold to a fellow collector and is not available).
