I maybe wore this twice indoors, and never on the original strap (just remounted). Crease marks on the strap from storage box but none from actual wear. Just timed enough to know it tells excellent time, then back on the shelf. I purchased because I wanted to scratch that Kobold itch (without getting scammed lol) with a Fricker looking case, just too much competition with my other watches.
