There is no right answer to this question, no "perfect leather" - some people prefer a strap that patinas, while others prefer a strap that looks pristine even after multiple uses. The leather to choose depends on the specific qualities that you are looking for in the strap, which varies from individual to individual, watch to watch.
Nonetheless, rest assured that we only use the best quality leather that we know of, and widely used by leathercrafters around the world - full grain leather, and not that genuine leatherrubbish that is so often found on leather watch straps.
