Hi Guys,

I hope that you are all doing well. I have a chance of acquiring a B&R Space 3 chronograph, but there is currently a issue with the winding crown. As I am sure that you are aware, this model has a unusual winding crown, which has a outer sleeve. The sleeve locking system is not working at present, as there is some wear to the locking groove. The ball bearing is functioning correctly, as the crown sleeve will lock if the crown is not fully tightened.

If someone could let me know the price of replacing the crown or just the crown sleeve, it would be gratefully appreciated, as I would love to purchase this watch, but I am worried about excessive repair costs. Many thanks.
