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

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.

Handmade leather care balm, made of natural ingredients: 100% organic cocoa butter, 100% organic beeswax, 100% pure organic almond oil. This balm is perfect to restore, protect and preserve vegetable tanned leather watch bands. The leather balm is tested with vegetable tanned leather and fits the majority of the leather types (excluding suede and shell cordovan leather straps).

This balm fits perfectly vintage old leather straps and helps to prevent leather drying. When using regularly, the balm helps to increase the strap longevity by smoothing the leather.

Leather strap becomes darker when using this balm for a while. Please, apply a very small quantity first and test before applying on a very small leather piece (inner part of the watch strap). Clean and dry leather strap before applying.

No animal fats, preservatives or petroleum-based products are added.

We are happy to cooperate with the makers of Smith's balm, family business in Maine.

More information about taking care of your leather straps.

NB! Ammo straps are made of real vintage leather from 1900th-1980th. The leather might get dry and requires special leather care balm to avoid drying and breaking. The leather balms also increase longevity of the leather straps and make them softer. We have tested and highly recommend applying small amount of natural Smith's Balm (made of organic cocoa butter, beeswax and 100% pure sweet almond oil) weekly to the valuable Ammo watch band.
