Tips On How To Replace Broken Stem

[haratua]

In the excitement of repair, I accidentally broke the stem off.

What are the tips on getting a replacement or fixing this?

 

This is of the SeaGull TY2867 movement, not one of the popular movements.

I checked website like Esslinger, the stem replacement goes by brand like ISA, Ronda, Seiko, etc.

Do I get whole new stem, or just get an extender?

 

If I getting a new stem, what to get (how can I tell which is the right one since this is not of a popular movement that I can order by caliber number)?

 

Also, will an extender works, and is it a better/worse option? What's the general guidelines, whether to replace the whole stem or get an extender?

 

Much appreciate your always helpful insights. Thanks

If I was you I would just use a stem extension cut as short as possible. And use thread lock to make sure it is well secure. Well done for extracting the broken part from the crown - that can be tricky sometimes.

I was quite lucky in removing the broken part because it didn't break cleanly. There was still a small tip for me to use a pair of fine-tip pliers to take it off.

 

Thanks for the advice. I will get a stem extender. I will post pictures once it's fixed. 

 

Btw, what's the best way to cut the stem extension, do you cut it with broaches and file it?

Trim it with end cutters and then use a file or oil stone to bring it to finish it off.

Following your advice, I decided to fix the broken stem with a stem extension.

 

 

After cutting the stem using an end cutter, I use a small oil stone to file down the stem.

 

 

It takes about three tries to file down the stem to make a perfect fit.

Excellent work!
