W10 1970's Pattern 24 Jewel Automatic

MWC has been producing W10 models for decades, but this particular model is a significantly updated version of the original 1960/70s design. It retains the classic outward appearance while incorporating modern enhancements. The most notable upgrades are an enhanced water resistance rating of 100m (330ft), bringing it up to contemporary standards, and a screw-down crown, which reduces the risk of the crown being lost or damaged if snagged.

Unlike other manufacturers that still use an acrylic crystal, limiting water resistance to 50m (165ft), this model features a more durable construction. The Automatic W10s have a robust stainless steel satin finish case made from Military Grade 316L stainless steel, designed to endure extreme conditions. The watch also includes a sweep second hand, a black dial, and luminous markings.

Equipped with a high-performance 24-jewel self-winding movement, this watch offers a 41-hour reserve and can be hand-wound if not used daily. Additionally, the current watch has a screw caseback for easier maintenance. Older models and current CWC models are serviced by removing the crystal, making maintenance challenging for many watchmakers.

The history of the W10 models is quite interesting. The hand-wound version of this automatic self-winding W10 was the predecessor to the quartz G10/98 models used by today's armed forces. Interestingly, there was a plan in 1980 by the British MOD to retain this case pattern with a quartz movement, but the quartz movements were too thick to fit into the case. This led to the development of the G10 models we now see. The last two images in the gallery show a government specification sheet from February 1980 requesting tenders for the W10 pattern case.
