All about the MARATHON 36mm OFFICER MECHANICAL (GPM) WW194003SS-0101

Robust precision from Switzerland

This new field watch combines Swiss technology with a clear, practical design: inside works the high-torque quartz caliber ETA F06.115 HeavyDrive, manufactured by ETA SA in Grenchen, known for its reliability and additional HeavyDrive characteristic. The mechanism is complemented by a practical EOL indicator that signals the end of battery life — a feature that builds trust in critical moments.

Material choice with standards

The case is made of matte 316L stainless steel, which gains increased corrosion resistance through a Parkerizing treatment (phosphate conversion coating). This surface appears discreet, reduces reflections, and at the same time gives the watch a functional, almost instrumental appearance — robust but by no means rustic.

Readability in any position

The dial is clearly structured in black with 1–12 and 13–24 scales, making both military and civilian time formats equally readable. Hour, minute, and second hands as well as the indices are equipped with self-luminous tritium tubes that glow constantly and reliably independent of external light — a crucial advantage in poor visibility conditions.

Technology that protects

Above the dial lies a scratch-resistant sapphire crystal that protects the view and emphasizes the watch's durable quality. The crown is pressure-sealed, making operation simple yet secure; the construction achieves water resistance of 5 ATM / 60 m, enabling the watch to confidently meet everyday and outdoor demands.

Compact dimensions, thoughtful proportions

With a diameter of 36 mm, a lug-to-lug length of 44 mm, and a height of 11 mm, the watch offers a balanced wearing experience: prominent enough to act as an instrument, yet compact enough not to interfere with everyday life. The lug width of 16 mm completes the design harmoniously and allows comfortable adjustment to the wrist.

Functionality in detail

The caliber runs on three jewels and, in addition to timekeeping, also features an integrated date display that is discreetly integrated into everyday life. This mix of simple operation and technical substance makes the watch a reliable companion for any situation.

Selection for use

Two durable strap options were provided for rough everyday use: a black Marathon ballistic nylon strap according to DEFSTAN standard and a classic ballistic nylon strap. Both straps are designed for durability, tear resistance, and wearing comfort and are secured with a 316L stainless steel pin buckle.

Conclusion: honest instrument watch

In its combination of solid material, practical features like the EOL-Indicator, proven ETA electronics, and thoughtful ergonomics, this watch is aimed at people who want more than decoration: a reliable, durable tool watch that can perform equally well in everyday life and in the field.

FAQs

About me

My name is David, I was born in the late 60s in NRW, now live and work in the beautiful Harz Mountains, and have been running this watch shop, among other things, since spring 2022.

Since 2018, I have also been running my watch blog watchdavid.de, which features hundreds of reviews and watch news. Since then, I have taken thousands of professional watch photos for over 100 watch brands. Many photos can be found in my reviews. I am known worldwide for this.

As a result, I naturally had thousands of watches in my hands. And with this shop, I want to bring you closer to watches that have convinced me in many ways.

So come along on a journey full of watches... off the mainstream... and if you have a question, please feel free to ask me anytime via the form, chat, WhatsApp, email or phone.

I am very much looking forward to meeting you.

PS: My hobbies & passions include the internet (first agency already in 1996), Denmark, France's coasts (Brittany, Normandy & Côte d’Azur), hiking, e-MTB, sales (Bachelor of Sales) and photography.

My Achilles' heel includes children's chocolate, good food, sneakers & of course watches... :-)

Shipping & Insurance

Within Germany and the EU, I ship free of charge. Shipping is done via DHL and insured up to 500€, 2,500€, or 25,000€, depending on the watch value. The watches are thus always sufficiently insured.

The delivery time can be found in the description and/or under the shopping cart button. Some watches are only produced after ordering, others are brand new and, for example, only available in a few weeks (so-called PRE-SALE), etc...

Cancellation & Return Shipping

You can cancel your purchase within 14 days of receiving the goods.

I will cover the costs for the return shipping for you.

IMPORTANT: Do not send the watch back yourself, I will send you the free return label.

Please simply contact me for this. david@watchdavid.com

It is also important that the watch is unworn and free of signs of use. After successful inspection, I will refund you the purchase price. The refund will be made using the same payment method you used for the purchase.

Authenticity & Condition of the Watches

I guarantee you that all watches I offer are exclusively new original products. The watches come directly from the manufacturer and have had no previous owners, unless I explicitly point this out (e.g. so-called PHOTO WATCHES).

As an official dealer, I offer you exclusively authentic products. These are offered in the original packaging, with warranty card, etc., just as they are delivered by the dealer. Everything in the so-called full set. One delivers more, another less...

Warranty & Service

All watches purchased from me come with the international manufacturer's warranty, which usually lasts two years. Some brands even offer a warranty of up to 5 years.

If a warranty case occurs, I will take care of the shipping to the manufacturer or the responsible service center for you and also organize the return shipment to you. In addition, I handle all communication with the manufacturer so that you don't have to worry about anything.

Even after the warranty period has expired, I remain your contact person and support you with service questions or repairs.

No response received?

You wrote to me via the contact form, through the price proposal, directly by email, chat, but you haven't received a reply?

Then please check your SPAM folder! Many providers are getting crazier and pushing more and more into spam.

I usually answer every inquiry within 24 hours at the latest. On weekends, it can sometimes take a bit longer. As a rule, I respond within a few minutes or hours.

Something can slip past me sometimes too. Or the technology doesn't work as it should. Feel free to write to me again at david@watchdavid.com

Mechanics - Sometimes things can happen there too

Before I ship your order, I carefully check each watch for visible defects.

If a problem should occur, such as damage during transport, please inform me immediately. I will do everything possible to quickly find a solution and ensure that you are satisfied.

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!
