The Breitling Watch Source Forums

I think this might be my first post, You only post when you have an issue LOL.
I have a 2007 Breitling super avenger A13370 model.
I sent in in for service in 2016 to Breitling and they serviced the watch I think at the time it was about $1200. I'm sure now it would be in the $1400-1500 range no including the fact the watch is now broken, So I'm sure it would be in the $2500 Range to fix.
I'm not sure I want to spend $2500 on a watch worth 3K or less if it was in working order.

My question is the Crown broke off at the crown,
I see on ebay I can buy the part,

It show's the crown and tube, is it as simple as just unscrewing the tube and replacing the part?

I'm in the Orange county CA area I'm thinking it might be best to take it to a professional instead of attempting to do it myself.
I cant find any videos on youtube and their is not anything online I can find that shows how to install it.

Thank you for any help,
