I have a leather watch strap, which is supposed to be vegetable-tanned, full-grain leather, with nubuck lining (see attached photo). The strap is in this condition, after about three weeks of use. I showed it to someone more familiar with straps, and he said it isn't supposed to look so worn so soon, and criticized the leather quality. Can anyone verify this? How do I identify good quality leather for watch straps? Put it another way, are there any examples of how "good" leather straps are supposed to look after 3 weeks / a few months /a year? Thanks!
