A faithful reproduction of an Italian product, mainly by the fact that its function is uncertain at best! If you need a historical timepiece for a costume, you can't go wrong with this. These "work", which means there's usually movement on the clock face. Battery operated, no idea if those are replaceable.
From what we gather, these try to portray specific pocket watches issued to a certain Italian WW2 era unit. We strongly feel the actual wartime watches were of much higher quality.
Made of metal-like substance, with an actually quite formidable weight.
The silver watch opens up nicely and is decorated with the Xa MAS unit logo.
Manufacturer unknown, but someone gave these CE approvals! These are some kind of surplus from somewhere, we wouldn't normally buy these cheap pocket watches. We say it again: No guarantee of actual function, or how these keep in the time! This is essentially a Pocket Watch Shaped Object.
Remove the plastic shim, press the top knob down. Now the watch starts to run. Maybe. Set the time by turning the knob. The functionality of this feature is a strong 'maybe' too.
