The original concept was to product an inexpensive field watch for infantry and general service troops, with a metal case and no serviceable or maintainable parts. The design of the dial was identical to US specification MIL-W-3818B watches which were already in production.

On October 10th a new specification MIL-W-46374D was published which set down the design for a large range of watches for various applications. This specification continues today with additional amendments and changes to the original MIL-W-46374 spec but it traces its roots back directly to the MIL-W-46374 which is the specification which was the main inspiration for this model.

MWC made watches of this type back in the 1970s and 80s but in 2007 received numerous enquiries aasking to re-run the plastic Vietnam watches which were made previously. The decisive moment was in July 2008 when a request was received from a film company to make a fairly large number for a forthcoming production and this combined with demand from various re-enactment groups persuaded us the time was right to bring it back.
