Montblanc Question

[Sprezzatura!,]

Hi there,

Have been a watch collector for many years.

Have toyed with the idea of buying a good quality pen a few times over the years, but they aren’t my bag, despite using one throughout each day.

I intend on buying a Meisterstuck Platinum Coated Ballpoint Pen.

Question i have is, what size should i get?

I’m sure the advice will be to try them in store, but i already know most sizes will be fine for me.

If someone asked me the what the general sweet-spot for watch sizes would be, i’d say 40mm (despite smaller, and larger working fine for me).

Essentially, I’m asking what that universal size is for the Meisterstuck line?

Would appreciate the suggestions. I’m guessing most responses would be similar…
