A closer look
This is a two-piece watch strap designed for attachment to a timepiece. The primary material is black ostrich leather, characterized by its distinctive, raised quill pattern texture across the entire exterior surface. The color is a deep, consistent black with a subtle, semi-gloss finish that catches light to highlight the pebbled texture. Prominent, uniform white stitching runs along both long edges of each strap piece, providing a sharp visual contrast and reinforcing the construction. The stitching is executed with a consistent, tight thread density.
The strap is specified with a size gradient of 21 to 18, indicating the lug width at the watch head attachment is 21mm, tapering down to an 18mm width at the buckle end. Its overall length is designated as 120/80, meaning the longer piece measures 120mm and the shorter buckle-side piece is 80mm. The thickness is graduated, measuring approximately 4.2mm near the watch attachment and tapering to about 2.9mm at the opposite end. This tapering is visible in the profile view, showing the multi-layer construction.
The underside of the strap is lined with a smooth, tan-colored Zermatt leather, chosen for its odor-resistant properties. Sandwiched between the ostrich exterior and the Zermatt lining is a padding layer made from top-grain cowhide leather combined with Talin material, which gives the strap its subtle, rounded contour. All raw edges are meticulously finished with a black, imported edge paint that creates a smooth, sealed, and uniform boundary, preventing fraying and enhancing durability. The craftsmanship shows precise alignment of layers, clean edge finishing, and straight, even stitching without visible imperfections.
The longer strap piece features seven round, punched adjustment holes for the buckle tongue, spaced evenly apart. The shorter piece holds two keepers (loops) made from the same black ostrich leather, designed to secure the strap tail. The buckle end of the shorter piece is prepared for buckle attachment, but the buckle itself is not included. This strap is engineered for compatibility with various watch models and can be adapted to use quick-release spring bars for easy tool-free installation and removal. The overall style is classic
