SKU: W10/S/ND/MQ
The hand-wound version of this hybrid W10 was the predecessor to the quartz G10/98 models used by the armed forces of today. Interestingly in the British MOD specifications from February 1980 inviting companies to tender for contracts to supply watches to the British forces (see last three images), the requirement foresaw that the W10 pattern watches would continue with a quartz movement, however, there was a major problem because at that time no quartz movement could fit the case due to being far too thick. This situation led to the watches we still refer to as the G10 which are the current issue watches.
Sometime back a  watchmaker we work with was looking at a W10 casing and discovered that a Swiss quartz Ronda 715 movement would fit perfectly he then tried a sweep second-hand hybrid movement which he thought more in keeping with the 1970s design and this hybrid movement fitted perfectly, this meant that while the model in the MOD spec sheet was not able to be produced 40 years ago it is now hence we developed this model which not only looks outwardly mechanical but also has the accuracy of a quartz watch, a glass crystal giving it 100m water resistance (the originals used perspex) and a screw-on caseback and a locking crown. Although this watch is a significantly updated version of the original 1960/70s models it successfully retains the originals outward appearance.

Hybrid watches essentially combine the best of both contemporary and traditional watchmaking technology. They bring together features from both conventional automatic watches and quartz watches. The biggest plus of hybrid watches is that other than a battery replacement periodically there is very little maintenance required. The technology of hybrid movements employs a battery powering the movement through coils and a quartz oscillator, the hands, however, are mechanically actuated and controlled. Essentially the movement is mechanical except it's powered by a battery and regulated by a crystal the only thing it doesn't have is a mainspring. This watch offers the ideal choice for buyers who would prefer the sweep secondhand seen in an automatic or manual wind watch with the hassle-free maintenance of a quartz model. 

The W10 Hybrid has a heavy stainless steel satin finish case made from Military Grade 316L stainless steel, it is very robust and tough and built to endure the most extreme of conditions, sweep second hand, black dial and luminous markings. Please note The watch uses Luminous Luminova paint although the watch carries a T for historical accuracy though no radioactive material is contained within the watch.
