Purchased a Nomos Orion in June and have worn it quite a bit without issue. On two occasions in high heat doing a lot of walking (10-15 miles around the city) I developed a fairly bad rash/dermatitis under the band.
Sweat/heat seems to be a factor, however I’m wondering if cordovan (horse) allergy is a thing? I don’t recall having this reaction to other leather bands in the past.
Ah ha, interesting. When doing some research I saw similar rashes from silicon apple watch bands and, knowing silicon is about as hypoallergenic as it gets, assumed it had to do with the heat.
I’ve ordered some perlon bands that I think I’ll swap out for the warmer months, and reserve the cordovan for the cooler half of the year and special occasions.
