TimberlandMen's Classic Leather Reversible Belt

when you buy a belt size, what hole in the belt is that size? middle, closet to the inside or outside? it would be nice to provide a range.

If I need a 125 cm belt, what size to buy?

The buckle on my belt broke after about 7 months; how can I get a replacement buckle?

Can this belt be cut down to size?
