It is the 32 mm. I haven't seen the new 38 mm one, although I did see a larger Oscar buckle belt that I assumed was the 42 mm. Maybe it was the new 38 mm.Is that the new 38mm width.
I like the new packaging, with a bag rather than a former; really useful for travel.
I like the dust bag too. The spiral curls up one part of the belt (towards the centre of the spiral) a bit too much, while this dust bag allows the belt to just curl a bit more naturally.
