The Adanac and Marathon Navigators were manufactured by the Swiss firm Gallet for the Canadian Marathon Watch Company and were supplied to the US Government across a number of contracts. Adanac-branded watches were issued in 1986 and 1988. Subsequent contracts were awarded for the Marathon-branded watch, which adopted tritium tubes but was otherwise almost identical to the Adanac version. This example was issued in February 1991, as marked on the case back.
Like the Adanac, the Marathon Navigator has a serviceable Harley Ronda 373 quartz movement, bidirectional rotating GMT bezel, screwdown crown, snap case back and removable battery hatch.
This example is has been fully serviced in our workshop and is in very good condition all round, as detailed in the condition report, and is supplied on the a high quality replica of the original black US Government issue single pass 19mm nylon strap.
The watch case is in good, clean cosmetic condition with some minor marks and wear from use. The case back has some minor marks and strap burn. The dial and hands are excellent. The original crystal is in very good condition with some minor marks. The bezel insert is in very good condition. Please refer to the images to make your own judgement about the condition of the watch.
Mechanically the watch was serviced in May 2026.
During the service the watch was fully stripped. The case parts were ultrasonically cleaned, with new battery hatch and back gasket fitted. The movement parts were mechanically and ultrasonically cleaned in waterless solutions and hot air dried. The movement was rebuilt, lubricated and regulated, with new 395 battery fitted. The original crystal was polished and is in good condition.
The bi-directional bezel was cleaned and refitted during servicing and operates correctly. The crown screws down tightly. Time adjust and hacking seconds work correctly with the crown unscrewed and pulled out.
The watch has been fully tested and on the bench is running at +0.01 seconds per day, equivalent to +0.31 seconds per month (the watch has to be regulated with the back removed, so in the image you can see the battery is being held in place with a rubber band). Note that accuracy in use may differ from this figure.
All round an very good, fully sorted example.
The watch is absolutely suitable for everyday use, but it is vintage watch so is not recommended for sports or use in extreme conditions. The watch has not been pressure tested so water resistance is not guaranteed. This watch is covered by our waterproof 6 month guarantee.
