This Endura watch is a bit of a Frankenwatch, meaning it was put together from 2 watches. It comes with a spare EB8800 movement. The watch runs and keeps time, but is temperamental. The spare movement runs for a few seconds, then stops. It is missing the click spring and screw. These are sold 'as is' and no guarantees. This pair is a great set for learning watchmaking skills, or parts. Please, no returns.
