Description
SKU: DIV2001/PVD/715LI
This watch, allocated the NSN number 6645-99-969-5589 by the MOD (Ministry of Defence) codification agency, traces its origins to watches MWC first manufactured between the early 1990s and 2004. Although some details, such as the dial design, changed over that period, the 1999-2001 pattern dial remains the clear winner due to its easily readable, uncluttered layout and excellent nighttime performance. This watch retains that original dial pattern.
Over the years, this watch has been significantly updated with the following main upgrades:
Transition from a Ronda 705 movement with a 5-year battery life to a Ronda 715li, which only requires a battery replacement every 10 years.
Upgrading the crystal from hardened mineral glass to sapphire, which is vastly superior due to its high scratch and shatter resistance.
Switching from a 60 or 90-click bezel to a 120-click bezel for more precise adjustments.
Because of its high specifications, this watch has received significant attention from various procurement agencies, hence the allocation of an NSN number, making it available to NATO forces worldwide.
The watch case is PVD treated, a finish often specified in military contracts for special forces units, anti-terrorist units, and various covert operations. In the PVD process, the steel is not black all the way through; the color is created by a special chemical PVD plating process, which is vastly superior to the painted finish used on many budget watches that can easily fade or rub off. The PVD process alters the color of the steel at a molecular level, ensuring it does not deteriorate even during heavy usage, though it can be compromised if the case is badly damaged or worn down by heavy abrasion against rocks or similar surfaces.
These watches are closely based on a case design originally made by the famous Swiss case-making firm MRP S.A. Other than a few minor updates, the case remains much the same as in the late 1970s. MRP was founded in 1953 by Marchand, Roth, and Petignat and was bought by Georges Hauert in 1979. The entire share capital now belongs to Patrick Hauert, keeping the company independent and strong.

In addition to MWC watches, other watches using this case pattern have been produced by companies such as Precista, Nilax, Elvia, and Heuer, the predecessors to Tag Heuer, who made the Heuer 844-1 in 1979. Chronosport also made the Sea Quartz 30, worn by Tom Selleck in the Magnum PI TV show. Elvia, another manufacturer from the 1970s, continues to produce watches using this case, and MWC is a factory-authorized distributor for this brand. CWC and various other companies also continue to use this case design. It's interesting that few people realize how historically significant this case pattern is and how well it has stood the test of time, having been in continuous production for over 40 years.
The basic design of these MWC watches goes back to the British Ministry of Defence (MOD) specification shown in the two images. The current NATO stock number allocation reflects the multiple improvements made possible by advancements in technology over the past three decades. While the updated models are virtually identical to the original watches in outward appearance, they are significantly superior from a technical perspective.
