I believe it is the Ref E858 K814 mechanical wind movement. Not many of the E858 were made. Measures 1 3/8 or 35mm wide not counting the crowns.
1 3/4 or 44.4mm lug to lug. Watch has discoloration to dial. Crystal has scratches/scuffs from use and age. Case has some scratches and some normal wear.The alarm function winds/sets properly and buzzes loudly. The time set functions properly but will not wind the mechanical movement. So the watch is Non-running and I will not guarantee accuracy. You may still need to have this cleaned, serviced, repaired etc to get it to your liking. Overall condition is visible in the pics. Ask all questions important to you! Please view all supersize and zoom in feature photos. Please be realistic in your expectations as this is not a brand new item. More pics available upon request.
