Strap for Broadway Day Date Automatic Steel / Grey / Bracelet

The Hamilton Broadway H43515135 features a 20mm lug width. This is the standard construction measurement for the 42mm case and is compatible with all aftermarket straps and bracelets designed for this dimension.

The choice depends on intended use and aesthetic preference. For formal or collector contexts, we recommend alligator leather with medium grain in tobacco brown or charcoal tones. For versatile everyday wear, vegetable-tanned calf offers natural patina development and proven durability. For active or aquatic use, FKM rubber or NATO fabric straps deliver functional performance without compromise.

Strap changes are performed via spring bars—two small metal pins that secure the strap to the case lugs. Using a dedicated tool or small flathead screwdriver, gently press one spring bar inward to release the pin, then withdraw the old strap and insert the new one. Repeat on the opposite lug. The operation requires care to avoid marking the case.

Yes, any strap with a 20mm lug width is mechanically compatible with the H43515135. Our artisanal straps at milanostraps.it are specifically manufactured for this width, ensuring perfect fit and precise mechanical tolerances. Compatibility is guaranteed across both leather and synthetic materials.

Leather strap longevity depends on material quality and frequency of wear. Artisanal-grade alligator or vegetable-tanned calf typically lasts 3–5 years with regular use, developing characteristic patina over time. Exposure to moisture and direct sunlight accelerates ageing. A well-maintained strap rotated with others can achieve extended lifespan, eventually becoming a personalised object of historical value.
