What to inspect
Because the model's selling point is that it is hand-wound at a low price, the common counterfeit fits a cheap quartz or an unbranded automatic. The direct check is the winding behaviour: a genuine H-50 has no rotor, cannot be shaken into life, and must be wound. A Khaki Field Mechanical with a seconds hand that runs without ever being wound is not one.
