Each strap consists of multiple layers, simply understood as the exterior, padding, and interior surfaces.
Unlike a cake, these layers are not just delicately stacked and held together with airy cream and good thoughts. To ensure they hold their place, each layer is prepared by thinning it at strategic points ('skiving') so that the strap thickness remains the same when folded over and sewn into place.
The layers are then glued together before cutting to size ('overcut').
Having been invented in the time of Constantine the Great, i.e. 4th century A.D., there can be no argument when describing saddle stitching as a time-tested technique. Its early use was, as its namesake states, for the securing of horse-riding saddles. What better guarantee of security is there for your wristwatch, then the survival of even the rough and tumble of horse-riding?
This method of stitching requires the passing through of needles from one side to the other, alternating throughout the sewn material. This first requires the meticulous preparation of stitch holes by our skilled artisans. There can be no mistake - leather is a natural surface held together by fibers at the microscopic level, and all the king's horses and all the king's men couldn't put a misapplied stitch hole back together again.
Then comes the actual stitchwork, a process of honed, consistent precision. The artisan passes through two needles in each successive stitch, taking care not to tangle or spear the trailing threads. With each stitch only millimeters apart, this segment of the process is one of the most time-consuming.
