All about the MARATHON 34mm Black General Purpose Mechanic (GPM) WW194003BK-0101
Light, Functional, and Uncompromising
The General Purpose Mechanical – GPM for short – is a modern duty watch with military DNA, manufactured according to the strict requirements of MIL-PRF-46374G, Type II, Class 4. This standard ensures that the watch functions reliably in extreme situations as well as in everyday life. Originally developed for the US military, the GPM remains a symbol of robust, practical watchmaking to this day.
Compactly Built for Maximum Performance
With a case diameter of 34 mm, the GPM offers a comfortable fit that is neither bulky nor obstructive. The casing is made of a high-strength composite fiber shell, ensuring exceptional durability with low weight. Ideal for individuals who want to barely feel their equipment – but must rely on it at all times.
Automatic Movement with Manual Winding Option
Inside, the proven Seiko NH35A automatic movement operates, which can be wound both by a self-winding rotor and manually via the crown. This dual power supply makes the watch particularly reliable, whether in civilian life or under difficult conditions. With 24 synthetic jewels, the movement ensures smooth operation and reduces friction to a minimum.
Military Functionality – Clearly Structured
The dial features a dual scale with 12-hour and 24-hour display, making it equally easy to read standard time and military time. A date display is intentionally not integrated into this model to keep readability clear and direct – in the spirit of a true field watch.
Visible at All Times – Even at Night
Tritium gas tubes on the hour markers and hands ensure excellent readability in complete darkness. Unlike conventional luminous paint, tritium is self-luminous and does not require an external light source for charging. This ensures the watch remains constantly readable day and night, for many years.
Resistant in Every Aspect
A scratch-resistant sapphire crystal protects the dial from impacts and wear. The watch is also water-resistant up to 3 ATM, making it splash and rain proof – perfect for daily use under realistic conditions. The push-pull crown contributes to the simple, functional appearance without sacrificing technical integrity.

FAQs
About David from WATCHDAVID
My name is David, and I've been deeply involved with watches for many years – not just as a dealer, but primarily as a tester, photographer, and classifier.
Since 2018, I’ve been running WATCHDAVID as an independent watch project featuring reviews, videos, and real-world wearing experiences. Many of the watches you'll find here have been on my own wrist – often for extended periods.
WATCHDAVID.SHOP is intentionally personal. I only sell watches that I genuinely stand behind – no anonymous mass-produced goods, no dropshipping, no "quick trends." Experience, transparency, and honest assessment are paramount to me.
And yes: I am not an anonymous seller. I enjoy good food, sneakers, and photography – and I have a proven weakness for Kinder Chocolate.
If you have any questions or are unsure, feel free to contact me directly. I will respond personally.
Shipping & Insurance
Within Germany and the EU, shipping is free of charge. Shipping is handled by DHL and insured up to €500, €2,500 or €25,000, depending on the watch's value. The watches are therefore always sufficiently insured.
You can find the delivery time in the description and/or below the shopping cart button. Some watches are only produced after an order is placed, while others are brand new and, for example, will only be available in a few weeks (so-called PRE-SALE), etc...
Revocation & Return Shipping
You can revoke your purchase within 14 days of receiving the goods.
I will cover the return shipping costs for you.
IMPORTANT: Do not send the watch back yourself; I will send you the free return label.
To do this, please simply contact me. david@watchdavid.com
It is also important that the watch is unworn and free of any signs of wear. After a successful inspection, I will refund the purchase price to you. The refund will be made using the same payment method you used for the purchase.
Authenticity & Condition of the Watches
I guarantee that all watches I offer are exclusively new, original goods. The watches come directly from the manufacturer and have had no previous owners, unless I explicitly state otherwise (e.g., so-called PHOTO WATCHES).
As an official dealer, I exclusively offer authentic products. These are offered in their original packaging, with a warranty card, etc., just as they are delivered by the dealer. Everything in a so-called Full Set. Some deliver more, some less...
Warranty & Service
All watches purchased from me come with the international manufacturer's warranty, which is usually two years. Some brands even offer a warranty of up to 5 years.
Should a warranty claim arise, I will take care of shipping the watch to the manufacturer or the responsible service center for you and will also organize its return to you. In addition, I will handle all communication with the manufacturer, so you don't have to worry about anything.
Even after the warranty period has expired, I will remain your contact person and support you with service questions or repairs.
No answer received?
You contacted me, via the contact form, about the price proposal, directly by email, chat, but you didn't receive a reply?
Then please check your SPAM folder! Many providers are getting crazier and crazier and are sending more and more to spam.
I usually answer every inquiry within 24 hours at the latest. On weekends, it may take a little longer. As a rule, I reply within a few minutes or hours.
Something can also slip through for me. Or the technology isn't working as it should. Feel free to contact me again. david@watchdavid.com
Mechanics - Sometimes things can go wrong
Before I ship your order, I carefully inspect each watch for visible defects.
However, should a problem arise, such as a defect during transit, please inform me immediately. I will do everything in my power to find a quick solution and ensure your satisfaction.
My goal is to offer you not only high-quality products but also a first-class shopping experience. I look forward to welcoming you as a satisfied customer!
