Introducing the Marathon General Purpose Mechanical (GPM) watch featuring a dual winding movement, scratch resistant sapphire crystal, and an improved water resistance.


Designed to be used in the field by infantry or other military personnel and built to the strict military standards of MIL-PRF-46374G, the GPM is just as at home being worn by a civilian as it is in uniform. The GPM is a true all purpose watch that will be your reliable companion for years.


The GPM uses a Japanese made “Dual Winding Movement” (DWM) and can be wound both by manually winding the crown or by use of the automatic self-winding rotor (transferred energy caused by the movement of the wrist). With the watch winding system, the user will notice that there is a mechanical noise and the rotor can be felt oscillating; reassuring the user that the automatic winding system is performing as intended. Once fully wound the GPM will run for approximately 41 hours without the need to be wound again, or can be worn to wind using the automatic self-winding rotor.


The case of the GPM is made from high-impact fibreshell, which does not sacrifice quality or durability while keeping weight low. Applied on the dial, minute, and hour hands are self contained Tritium gas filled tubes which ensure a constant glow for maximum low-light visibility. Tritium is a trusted source of illumination for military equipment, from watches to aeronautical displays, firearm sights, and binoculars. Tritium tubes glow on their own without the need for charging by an external light source, and will not fade in brightness making it an ideal configuration for nighttime or low light operation. The crystal (lens) of the GPM is made from sapphire ensuring the highest possible sratch resistance, legibility, and durability. This sapphire crystal is 3mm thick, providing added durability and impact resistance. Adding to the overall durability and reliability is the upgraded water resistance on the GPM giving it a water resistant of 3ATM , making sure that it will not yield to the elements.


Included with the GPM is a one piece nylon military strap which is made in accordance with MIL-S-46383B Type II and provides comfort and durability while remaining lightweight.


Overall assembly of the watch is performed in La Chaux de Fonds, Switzerland, combining the accuracy of a Marathon designed Japanese movement with reliability and Swiss craftsmanship to bring you a superb watch. The Marathon GPM is a watch that will provide you with years of accuracy, reliability, and enjoyment!

    I love this watch

    Posted by Jeff on 25th Jun 2017

    I have the Marathon GPM with the Swiss ETA-2801 movement. It gains 2 second per week which is phenomenally accurate for a mechanical watch. I had been looking for over ten years for just the right watch and this was it. I wanted a Swiss made mechanical, (a watch without a battery has a soul) a tough but stylish watch tested to actual military specifications for reliability, accuracy, stamina, and endurance.

    Disappointing

    Posted by Del Monte on 24th Aug 2014

    Supposedly accurate to a minimum 30 seconds a day, but not mine which gains or loses up to 10 minutes a day.

    If it was consistent in it's gain or loss it could be adjusted, but it's not so it can't.

    Would be better off with a sundial.

    Sorry.

    The tritium tubes work well though.

    P.S.

    Forgot to say the Tritium tube at 12 o'clock is orange, the other 13 tubes green. So in the night, when your brain is busy and sleep won't come, you can look across to this watch on the bedside table and see precisely just how slowly the night is passing.

    Unbelievable value

    Posted by Phoenix on 2nd May 2013

    I saw this in a HH catalogue. Don't know how I missed it online. Was contemplating buying a Ball watch but Don't need to now.
    Does everything I'm looking for in a watch; easily readable face, manual wind, sweep second-hand, tritium tubes and all for what I think is a remarkable price. Mine has settled down to an accuracy of around 3 seconds a day. Very acceptable. Not sure how waterproof it is and am reluctant to test it. No tritium light on second hand but at the price it's a great buy. Magnificent service as ever.
