Full-Grain Leather Watch Strap Stitch Detail

Develop a macro detail of a full-grain leather watch strap showing precise saddle stitching. Each stitch hole is perfectly spaced with slight compression where the thread pulls through. A subtle wear mark near the buckle suggests regular use. Composition: Frame tight on the stitching with the strap curving slightly across the frame. Light and color: Rich chestnut, warm cream thread, soft gray, and natural daylight. Use exact leather grain, realistic stitching texture, and proper material behavior. Keep one hero product, correct proportions, clean edges, and no visible logos, duplicate parts, random text, or clutter.
