In this episode we will cover the replacement of a watch crown.

From time to time, it may be difficult to find the exact crown and stem combination in order to repair a broken watch winder.

This video demonstrates the use of stem extensions in watch repair and the ideal situations which may warrant their use.

We go through all the measurements needed and demonstrate an effective method of installing the stem extension to the crown and stem.

This is a bonus video for those who have completed Level 1 of the watch repair course, but if you are a Patron you can also view this video as one of your perks.

Are stems (almost) always secured into the crown with red Loctite? If so, I’m surprised you just unscrewed the original stem without applyling quite some heat?

How are you measuring the male / female threads on these components? Just the diameter? Trial / error with components with known threads? Are there different pitches?
