I have a barrel for a 7750. After building up the movement it seems as though the main spring is "slipping". When I wind the watch I can feel the spring tension build the I get a click and the tension releases. I opened the barrel and had a look and to my novice eye things look fine. Normally I just buy a new barrel as they are relatively cheap. I have watched a few videos on spring replacement. Is this normal? Did something just come loose? The arber inside the spring looks like it just has a catch that when its turned it catchs the spring. Im guessing this is designed to slip to prevent overwinding however its slipping after two turns of the stem. Anyway. If anybody has any insight id appreciate it. Thanks.

If no scratch mark inside of the barrel then arbor discharges the power, just shape the spring wrapping around and holding the arbor securely. Grease the barrel.

You need braking grease on inner walls of barrel.

You're welcomed. If you need a little braking grease to finish this project, I can send you a few cc's in a zip baggie and mail it to you. PM me with your address.
