Using the RS winder

Step by step instructions (or just watch a video):

1. Place the plunger into the housing barrel.
2. Place the mainspring into the arbour rod on the winder base.
3. Use a tweezer to latch the arbour hook into the mainspring hole, make sure to follow the recommended style.
4. Carefully put the housing barrel and winder parts together. Take care not to wind in reverse as this will unlatch the anchor.
5. Wind the mainspring until (both) end tails of the mainspring sticks out. Gently push it in such that both tails are in the barrel. Continue to wind a little bit more until it goes in completely and can no longer be seen.
6. Once done, unwind by twisting in the reverse direction until there is no more backpressure from the mainspring. The anchor should naturally unlatch, allowing you to easily take off the winder base part. If the mainspring is still latched, then gently unwind a little bit more.
7. Next, place the housing barrel inside the setter bowl recess and press it. The mainspring will now be extruded by a small amount.
8. Fit the actual mainspring barrel into the extruded portion of the mainspring.
9. Place the parts on a level surface, and press the plunger to slip the mainspring into the barrel.
   • You may flip the setter bowl part and use it as a level surface for plunging the mainspring in safely.
   • The setter bowl part can also be used to snap the barrel lid back on.
