All about the MARATHON 36mm OFFICER'S MECHANICAL (GPM) WW194003SS-0101
Classic Design for Everyday Use
The Marathon Officer's Watch combines traditional watchmaking with modern functionality, presenting itself as a compact, robust companion for everyday life. With a case diameter of 36 mm, a height of 11 mm, and a lug width of 16 mm, this watch offers an ideal size for comfortable wear – whether in a professional environment, while traveling, or in daily life. Its balanced proportions make it sit comfortably on the wrist without being bulky.
Mechanical Heart with Military Precision
Behind its unassuming exterior works the reliable ETA 2801 hand-wound movement, which, with its 18 jewels, ensures precise timekeeping and a long service life. The watch is known by various names, including Officer's Field Watch Mechanical (OFM) or General Purpose Mechanical in Stainless Steel (GPM-SS). The display includes two scales ranging from 1–12 and 13–24, allowing for easy reading of both standard and military time – a useful feature for professional and tactical applications.

Robust Features for Any Environment
Thanks to its Tritium gas tubes, the watch offers constant luminosity – without any external light source. This technology guarantees optimal readability even in complete darkness and is significantly superior to photoluminescent paint in its durability. The dial surface is protected by durable sapphire crystal, known for its high scratch resistance and longevity.
Durable and Functional
The case is made of high-quality 316L stainless steel and has a parkerized finish, which gives the watch a matte, subtle look while providing additional scratch and corrosion resistance. The pressure-sealed crown contributes to water resistance up to 5 ATM and reliably protects the watch's interior from moisture – sufficient for rain showers or everyday contact with water. A rotating bezel was deliberately omitted to preserve the simple, functional design.
A Watch with Character
The Officer's Watch is a timepiece characterized by its military origin, mechanical precision, and durable construction. It is designed for those who seek a minimalist, reliable, and authentic watch that balances traditional craftsmanship with functional robustness – both in civilian everyday life and under challenging conditions.

FAQs
About David from WATCHDAVID
Behind WATCHDAVID.SHOP, I, David Drilling, stand as a true watch enthusiast, watch photographer, and independent tester. Since 2018, I have been providing honest wear reports on my channels. In my shop, I exclusively sell watches whose quality and history I have personally verified. No anonymous mass-produced goods, but personal expertise.
Shipping & No Import Charges
Shipping within Germany and the EU is completely free for you and fully insured via DHL or FedEx Express. Important for you: There are guaranteed to be no import duties, taxes or hidden fees. The exact delivery time for your model will always be transparently displayed directly above the "Buy" button.
Cancellations & Free Returns
You can easily cancel your purchase within 14 days. Unlike other retailers, I will cover the full cost of your return shipping within the EU. Simply send me a short email to david@watchdavid.com and I will send you your free DHL return label. It doesn't get any more risk-free than that.
Authenticity & Condition of the Watches
I guarantee you 100% that all watches offered are unworn, brand new original goods. In the shop, I strictly differentiate between regular new goods directly from the manufacturer and exclusive photo watches. Photo watches are models that I have used for my videos or photos, or that come from a return. I sell them absolutely honestly as used and significantly reduced – but the full manufacturer's warranty only begins on the day of your purchase!
Warranty & David's "All-Round Carefree Service"
Every watch comes with the full, international manufacturer's warranty (at least 2 years). In the event of a warranty claim, you'll have absolutely no stress: I'll handle all communication with the brand and organize insured round-trip shipping for you. Even after the warranty period expires, I remain your personal point of contact for service inquiries.
Quality Control
Mechanical watches are fascinating masterpieces. Before dispatch, each watch undergoes a thorough optical and mechanical final inspection. Should a problem ever arise despite our secure transport protection, please inform me immediately by email. I will promptly arrange for a quick, uncomplicated replacement.
