Made to Measure

The strap for this watch is made to measure

On the Hamilton Boulton the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

What is the lug width of the Hamilton Boulton H13331553?

The lug of the Hamilton Boulton H13331553 measures exactly 18 millimeters in width. This measurement is specific to this model and ensures proper strap accommodation in the case lugs. Always verify the measurement with a digital caliper in the deepest part of the lug.

Which strap is best for the Hamilton Boulton H13331553?

The choice depends on usage context and aesthetic preferences. For formal elegance, dark brown or black alligator is the most authentic choice. For everyday versatility, cognac-colored aged calf offers comfort and practicality. For classic-sportive style, navy blue NATO is ideal. Textured rubber represents the most contemporary solution.

What is the average lifespan of a leather strap for the Hamilton Boulton H13331553?

Lifespan depends on usage intensity and leather quality. A quality alligator or calf strap, with moderate wear, typically lasts 3-5 years before requiring replacement. Superior leather, properly conditioned and rotated among multiple straps, can last over 7 years. Wear always begins at the stitching and flex points near the lugs.
