SKU Code: G10SL/200

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

Combining the best of new and traditional technology, this model retains all the popular features of the 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.

The self-luminous system ensures easy readability at night. The MKV 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. While the vials contain radioactive gas, their combined amount is well below the personal limit of 25 millicuries, as per U.S. Nuclear Regulatory Commission regulations (10 CFR 30.15).

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 can gradually fade.

The standard MWC G10 is one of MWC's 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.

The G10 SL MKV is supplied with a heavyweight NATO webbing strap. The reverse of the case features various contract markings.

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.
