Watch Strap Size Chart and Measuring Instructions
Step 1: Measure Lug Width
- Using a ruler or caliper, measure the width of the space between the lugs of your watch where the strap will attach. This measurement will determine the lug width.

Step 2: Measure Wrist Size
- Wrap a flexible measuring tape or string snugly around your wrist, just below the wrist bone.
- Note the measurement in inches or centimeters.

Step 3: Determine Strap Length
- Measure the distance between the lug ends of your watch to determine the ideal strap length. This measurement should correspond to your wrist size and desired fit.
- For a comfortable fit, add 1,5 to 2 inches (3.5 to 5 centimeters) to your wrist size measurement.
Step 4: Consult the Size Chart
| Wrist size (inch/cm) | Watch strap length (2 pieces) | Watch strap length (one-piece) |
|
5.5 - 6.5 inch / 14 - 16.5 cm |
S: 110-70 mm | 230 cm |

Tapered sizes:
Tapered size refers to a gradual reduction in watch strap width from one end to the other. In the context of watch straps, a tapered design typically features a wider width near the lug attachment point of the watch and gradually narrows towards the buckle or clasp end. This tapered shape not only enhances the aesthetic appeal of the strap but also offers a comfortable fit, ensuring it conforms smoothly to the wrist. Tapered straps are often favored for their stylish look and ergonomic design, providing a sleek and refined appearance when paired with various timepieces.

Please Note:
The wrist size mentioned refers to the circumference of your wrist at the location where you typically wear your watch.
The length guide provided is approximate and applies to the straps depicted in the images. Variations in fit may arise due to variances in wrist shapes, buckle or clasp types, and differences in watch case sizes or shapes, which cannot be entirely accounted for.
Additionally, individual differences in hand size and structure may further influence fit.
