AN5740 12h Black

We have reprinted the masterpiece AN5740 Master Navigation Watch so that it can be used not only as a pocket watch but also as a wristwatch.
This is a navigation pocket watch used by the US Army and Navy during World War II. The model name is "AN5740". "A" stands for ARMY, and "N stands for Navy. We attached a specialized case to this pocket watch to create a watch that can be enjoyed as both a wristwatch and a pocket watch. (Design registration)
Even in modern times, there are pocket watches wrapped in leather covers to turn them into wristwatches. However, it inevitably ends up being large and bulky. The strap cover hides the shape of the pocket watch and spoils the original shape and atmosphere of the pocket watch. The method of welding the lugs is certainly simple, but as a pocket watch, it is no less enjoyable. With this product, you can enjoy it both as a pocket watch and as a wristwatch. This text version is simple and has excellent visibility.
I tried fitting a small pocket watch that was actually used by US military nurses into the AN5740 case.
It uses a 12-hour quartz movement made by Switzerland's Ronda company.
