Bergeon Mainspring Winder to Handle Size

[Curare]

Hi All

I have a set of the Chinese mainspring winders, and are considering buying a few specific Bergeon Winders.

Could someone who owns some Bergeon winders please provide a measurement for me, I am checking  whether I can use my Chinese handle (tight arse) to hold the Bergeon winders.

Chinese measurements are:

Handle ID =  12.05 mm

Winder OD = 12.00 mm

Pin OD = 1.50 mm (that locates in the handle slot)

I have seen a few Youtube videos were they don't use a handle just hold the winders, anyone practise this out there ?

Thanks

I have Bergeon winders #6 and #7. I don't have a handle, probably using a handle it's a much nicer experience but they are perfectly usable without one.

I have a Bergeon set, a Chinese set, and and anonymous set (in aluminium), and all of the handles and winders are interchangeable.

There are slight variations in the fit but essentially they all fit and work.
