The ultimate bespoke watch strap guide
Design a strap that fits your watch—and your style—perfectly. 1. The Measurements (Crucial Step) Strap Width This is the most technical part. You will see two numbers (e.g., 20/18mm). First number (Lug Width): The distance between the "horns" of your watch case. It must match exactly. Second number (Buckle Width): The width at the buckle end. A "taper" (e.g., 20mm narrowing to 16mm) creates a vintage, elegant look, while a straight strap (20/20mm) looks sportier and bolder. Strap Length This determines how the strap fits your wrist circumference. Small (105/70mm): For thin wrists (approx. 15-16.5cm). Medium (115/75mm): The industry standard (approx. 16.5-18cm). Large (125/85mm): For larger wrists (18cm+). Note: The first number is the long part (tail), the second is the short part (buckle side). 2. The Profile & Shape Thickness Flat (2-2.5mm): Thin and sleek. Best for dress watches and vintage timepieces that need to slip under a shirt cuff. Padded (Round or Square profile): Has volume in the center. Adds substance and robustness. Ideal for chronographs (like Speedmasters) or larger modern watches. Tip Shape The shape of the strap's end (the tail). Classic / Boat: The standard pointed tip. Timeless elegance. Square: Often associated with vintage styles or Panerai watches. Round: A softer, more contemporary look. 3. The Finishing Details Stitching Tone-on-Tone: The thread matches the leather color exactly. Discreet and dressy. Contrast Stitching: Usually white or cream thread on dark leather. Highlights the craftsmanship and gives a sporty racing look. Edges Cut Edge (Rembordé): The sides are painted/waxed. Clean and modern. Folded Edge: The leather is wrapped around the side. Very classic and durable. Lining (The inner side) Calf Leather: Comfortable and soft. Traditional feel. Rubber / Caoutchouc: Highly recommended if you live in hot climates or sweat often. It protects the alligator leather from moisture and extends the strap's life. 4. Hardware & Functionality Buckle Pin Notch Yes: Select this if you plan to use your own buckle that has a central pin (ardillon). No: Select this only if you are using a Deployant Clasp (butterfly style) that does not require a pin slot. Quick Release Springbars Standard: Requires a tool to remove the strap. Quick Release: Features a small knob allowing you to change straps with your fingernail in seconds. Highly recommended for versatility. Loops (Keepers) Standard: One fixed loop (near the buckle) and one floating loop. Wide: A single, wider floating loop (often seen on military or heavy-duty styles).

⌚ Complete Guide to Choosing Your Watch Strap Choosing the right watch strap ensures both style and comfort. Follow these simple steps. If you have any questions, please don't hesitate to contact us for personalised advice. Step 1: Determine the strap Width (Lug Width) This is the most crucial measure for adjustment. Measure the lug width: Always measure the space between the lugs of the watch (where the strap attaches to the case) and not your old strap (which may have shrunk). Check this tip: The width is often engraved on the back of your current strap. Example: If the space between the lugs measures 22 mm, you need a 22 mm strap. Step 2: Choose the strap Length The ideal Length depends on the size of your wrist. A. If you know the current Length: Lay the watch flat. Measure the loop part (Part A , without the loop itself). Measure the tip section (Part B ). Total Length = A + B B. If you would like a new Length (Wrist): Measure your wrist with a tape measure and use the size chart to find the ideal size (Length A+B combined): Wrist circumference Total Length (A+B) strap Size Less than 170 mm 160 mm S 170 to 190 mm 180 mm M 190 to 210 mm 200 mm L Over 210 mm 220 mm XL Step 3: Choose the Loop Type and Width The type of clasp influences both aesthetics and security. Pay attention to the measurement: For the buckle, measure the width of the strap where the buckle attaches , as many straps taper (are thinned) between the lug and the clasp.
