I've ordered numerous Martu straps and I've found them to be of exceptional high quality, most specifically in leather quality and build. Value for the money, there is no other better watch strap out there. If the straps in this drop don't interest you and you're a picky watch snob like me, you owe it to yourself to browse the massive selections of straps at the Martu site (martuleather.com). My only criticism is that the strap photos on the site could be better.
Also a heads up... If you have larger wrists like my fat 8" ones, the default Martu strap length is the same standard size on most watches, but the last hole on the strap is located further in and winds up being tighter than most other straps I've used. Martu offers multiple larger sizes at their site, so up-size accordingly. Martu being a custom strap maker also offers smaller straps too of course.
