Strap for Jazzmaster Quartz Stainless Steel / Black / Bracelet

The lug width of the Hamilton Jazzmaster H32451131 is 20 mm. This measurement is the distance between the inner lugs of the case and must be respected exactly when choosing an aftermarket strap to ensure precise fit without lateral gaps.

The ideal strap depends on intended use. For formal occasions, we recommend vegetable-tanned calf leather in dark brown or alligator. For daily wear, NATO canvas in grey or navy offers versatility. In summer, FKM rubber ensures comfort and practicality. Atelier Casati Milano customises the choice based on your style and specific dial variant.

Strap replacement is done by removing the spring bars (small metal pins) connecting the lug to the case horns. Use a dedicated spring bar tool or consult a professional watchmaker to avoid scratches. Atelier Casati Milano also offers strap change service by appointment at the Milan location.

Yes, any strap with a 20 mm lug width is physically compatible. However, we recommend verifying the quality of construction and spring bar finishing (which must be stainless steel) to ensure durability and aesthetic coherence with the timepiece.

A high-quality calf leather strap with vegetable tanning, such as those from Atelier Casati Milano, typically lasts 3–5 years with daily wear. Longevity depends on factors like humidity exposure, perspiration, extreme temperatures and cleaning frequency. Regular maintenance (protective balm, drying after exposure) significantly extends strap life.
