Balance staff

[Tore]

I will order a balancestaff from balancestaffs.com, but i am not sure what Ø125 means. Is it diameter off the balance wheel?

[nickelsilver]

That's the diameter of the hole in the balance wheel.

Your question was already answered by Nickelsilver. I just want to add my comment before you spend 35€

Your watch, 19''' was produced with three different Staffs: you may want to remove your existing staff first to check which one to order.

BS4652    19    482    240       

BS4653    19    484    240    

BS4654    19    488    239

Thank you, The pivot is broken, but that is no problem now. BS4654 is with Inca, BS4553 is Ø145, but i wonder what 19 stands for?

always a good operating procedure before ordering a balance staff measure all the dimensions and compare if you can with the staff your ordering before you order. Then when you get the staff you also want to measure everything again to avoid unpleasant surprises down the road.

then what's weird site below has two identical watches for the same number which represents the ligne size and then there's a third one that's a little variation in the height? which is why you have three staff sizes apparently.

In case your measured diameter will be Ø145, not Ø125, let me know and I will provide another part number for the staff (way less expensive than 35 EUR)
