G10SL MKV 200m/660ft Water Resistant Military Watch with GTLS Tritium Light Sources, Sapphire Crystal and 10 Year Battery Life



Product Details

SKU Code: G10SL/200

This self-luminous G10 model is a significantly upgraded remake of a popular design from our past. It features a robust stainless steel case with 200m (660ft) water resistance, a screw-down crown, a screw caseback, a scratch-resistant sapphire crystal, and a 10-year battery life.

Combining the best of new and traditional technology, this model retains all the popular features of our conventional G10 Luminova models while incorporating cutting-edge self-luminous GTLS tritium vials. The specification of this watch adheres to American Military Specification Number: US MIL-W-46374F.

Key Features:

Superior Night Visibility: The self-luminous system ensures easy readability at night. The G10SL/200 model features a distinctive face layout, with the hour and minute hands each containing a brightly glowing vial of tritium gas. Additionally, it has two lights at the 12 o'clock position, a unique feature to MWC. The vials contain less than the personal limit of 25 millicuries of radioactive gas, complying with U.S. Nuclear Regulatory Commission regulations (10 CFR 30.15).

Tritium GTLS Tubes: Military watches of this type are among the easiest to read in low light or total darkness. The self-activated light source is up to 100 times brighter than traditional luminous paint. These light-emitting tubes require no battery power or any form of charging and never need servicing or maintenance. Their life expectancy is at least 10 years, after which they gradually fade.

Durability: The standard MWC G10 is one of our most tried and tested models, with earlier variants in service for over 40 years. This model shares a similar casing to the Luminova models, ensuring the same level of durability as our non-tritium versions.

Heavyweight NATO Webbing Strap: The G10SL/200 is supplied with a robust NATO webbing strap. The reverse of the case features various contract markings.

Benefits of Sapphire Crystal:

Many customers ask about the benefits of sapphire crystal over standard mineral crystal. Synthetic sapphire is the best material for watch crystals due to its strength and resistance to shattering and scratching. These characteristics make it highly desirable for military and security personnel, police officers, and outdoor enthusiasts, who make up over 70% of our customers. Watches with mineral glass crystals are more prone to damage, even when using hardened mineral crystals. The strength of sapphire crystals comes from a heat treatment process that removes internal stresses, followed by the application of two layers of anti-reflective coating. This durability is why sapphire crystal is also used in the latest iPhones. Although sapphire crystal comes at a higher price, it is typically only fitted to higher-end watches.

Experience the ultimate blend of durability, visibility, and long-term performance with the MWC G10SL/200, a timepiece built to withstand the most extreme conditions while providing unparalleled readability and functionality.
