    Removing EB 8800 stem from movement

    Hi Guys I have a question about a Bettlach or EB 8800 movement. The stem is broken off in it and I cannot figure how to get it out. I have taken stems out of other movements but this one has me stumped. Sorry about the double pictures. Any advise would be appreciated. Thanks Benruslover

    Disassemble it and the remainder should fall out of the winding pinion/clutch. p

    The arrows point at the setlever.

    The red arrow points to the shaft on which the setlever pivots. This shaft protrudes through the bridge on the other side of the movement and is depressed to allow removal of the stem under normal circumstance.

    The green arrow point to the stud which protruding from the other side of the setlever. This stud engages a notch in the stem thereby retaining it and facilitating the transition between setting and winding.

    Thanks Pithy That makes more sense. I tried that but I guess I did not push hard enough. It should slip right out then. I have never worked on these before and was unfamiliar with it. Thanks so much for the pictures They really help a lot. Benruslover

    You may have to depress that button even slightly below the level of the bridge. If you give the movement a rap against the bench top - the stem may fall out. I view this as an almost single use caliber. Note the mainspring barrel mounting. Crude. p

    Hi Pithy I know this is not an expensive movement or a great movement. I have worked on some of the Benrus Fe calibers which is an ETA 2451 that has much respect in the watch community. Any movement that I can get running is a success. I get stuck on some of the dumbest things and I am so glad there is someone to turn to if needs be. Thank you Benruslover
