It is with regret that as of the 11/08/26 we will no longer offer shipping options to Europe. The new EU packaging rules make it impossible for small sellers to continue trading in the EU. The €3 per item rule plus the packaging rules now make it uneconomical. We may find a solution in the future via our ebay store.

Stems

Winding Stems - Part # 401
With so many calibres both past and present it can be hard to find the right stem for your movement, but at WWP we hope to cover as many as possible.
We stock a huge assortment of stems covering nearly all major known brands as well as a few obsolete ones. With over 5000 calibres in stock it will take time to add our inventory but please be patient as we try to update our stock
