Marathon General Purpose Mechanical – reliable field watches for everyday use and tasks
Marathon General Purpose Mechanical (GPM) watches are classic “field watches” created to military standards and designed for maximum reliability and durability. They are ideal for both field conditions and everyday wear.
Features:
1. Movement: Japan Seiko NH35A (24 jewels), which supports both automatic and manual winding.
2. Power reserve: approximately 41 hours – enough for about 1.5 days without re-winding.
3. Case: lightweight composite case (fibreshell) with a 316L stainless steel back cover.
4. Glass: sapphire – durable and scratch-resistant.
5. Illumination: self-illuminating tritium gas tubes on the hands and markers – constant glow in the dark without the need for “charging” from light.
6. Water resistance: up to 30 m (3 ATM) – protection from rain, splashes, and moisture during everyday wear.
7. Strap: durable military/tactical nylon – lightweight, comfortable, and durable.
8. Dial design: simple, “field” style – matte black background with a two-level scale of easy-to-read Arabic numerals (12-/24-hour).
Key advantages
– Maximum reliability and durability. The casing and mechanism are designed to MIL-PRF-46374G, Type II, Class 4 standards to withstand field conditions, shocks, dust, and moisture.
– Constant visibility of time, day, and night. The tritium illumination works without recharging, is visible even in complete darkness, and has a guaranteed service life of 25 years.
– Reliable and simple mechanism. The mechanism can be wound manually or left to wind automatically – without unnecessary batteries or noise, with a classic “mechanical” character.
– Versatile design. The watch looks equally good with tactical gear, “field” clothing, or in combination with everyday and classic styles.
Who is this watch for?
1. For military personnel, tacticians, and instructors – as a reliable tool in the field or during missions.
2. For tourists, travelers, and outdoor enthusiasts – durable, lightweight, resistant to adverse conditions, water, and drops.
3. For everyday use (EDC) – as a stylish, durable, and practical accessory for everyday use.
4. For those who appreciate wristwatches with history, a classic “mechanical” spirit, and long-lasting performance.
Care recommendations
– After exposure to moisture, dry the watch and make sure the crown is closed.
– Wipe the case and glass with a soft cloth from time to time, avoiding harsh chemicals.
