The larger size sits well on my wrist, and the minimalist case makes the most of the eye-catching texture of the Silvercut dial. If you’ve worn any smaller NOMOS models, the 39 versions will feel big, but for me, the effect is visual, with little impact on wrist in terms of comfort. The 38.5mm size is a considered, and wise, play towards a larger size that isn’t too big for most modern watch buyers. While I’m no watch brand executive, there is a case here for simplifying the NOMOS line up and I think it would make sense to focus on the 35mm and 39mm sizing for these core models going forward. Right now, there are so many sizes and variants of most of the core products – Tangente, Orion, etc. – that it can get a bit confusing. This is only exacerbated by the fact that the so-called 39 is really 38.5mm, so the naming isn't even always the right guide to go by.
