Strap for Broadway Day Date Automatic Steel / Grey

The lug width of the Hamilton Broadway H43515735 is 20mm. This dimension requires specific, non-standard straps. To verify with precision, remove the strap from the watch and measure the internal distance between the lugs using a digital calliper.

The best strap depends on usage: alligator in black or tan conveys formal elegance whilst harmonising with the sunburst dial; vegetable-tanned calf in cognac echoes the rose gold-toned hands; a navy NATO offers sport versatility; a grey rubber strap suits intensive activities. Your choice should reflect your primary wearing context.

To change the strap, use a spring bar tool. Position the tip in the lug hole, press gently to compress the internal spring, and extract the spring bar from the case. Repeat on the opposite lug. Align the new strap with the spring bars and press until the click locks.

Yes, any strap with a 20mm lug width is compatible. Verify the measured width is precisely 20mm and spring bar diameter is standard (1.8mm or 2.0mm). Leather, fabric and rubber straps meeting these specifications are fully compatible and allow aesthetic personalisation.

Longevity depends on material and maintenance. Quality artisanal alligator or vegetable-tanned calf lasts 3–5 years of daily wear, developing patina over time. Rubber maintains elasticity 4–6 years before hardening. NATO canvas resists 5–7 years. Condition leather every 6–12 months and dry quickly after prolonged moisture to extend strap lifespan significantly.
