Frequently asked questions

What is the lug width of the Hamilton Broadway H43311915?

The Hamilton Broadway H43311915 is equipped with 20mm lugs. This measurement is precise and can be verified by placing a digital calliper between the internal lug holes. Accurate measurement is essential to ensure perfect fit of an aftermarket strap.

Which strap is most suitable for the Hamilton Broadway H43311915?

For the Broadway H43311915, we recommend alligator straps in grey or black with aged patina, or vegetable-tanned calf leather with fine grain. For versatility, heavy-duty cordura NATO straps offer a balance between aesthetics and practicality. Rubber is ideal for humid and hot environments, maintaining aesthetic definition without yielding to summer torsion.

How do I change the strap on my Hamilton Broadway H43311915?

Strap replacement requires the use of a spring bar removal tool. Position the device under the lug pin to release the internal spring, then remove the pin. Repeat from the other side. Once the case is free, insert the new strap pins, ensuring they seat correctly. Avoid abrupt movements that could damage the lug.

Can I use an aftermarket strap on a Hamilton Broadway H43311915?

Yes, provided it is specifically manufactured for 20mm lug width. Our straps are handcrafted and calibrated according to consistent sectional standards. Always verify dimensions before purchase. The construction quality of the aftermarket strap significantly determines the final aesthetic experience of the watch.

How long does a leather strap last on the Broadway H43311915?

A quality leather strap, with vegetable tanning, maintains structural integrity for 3-5 years under normal use conditions. Longevity depends on sun exposure, humidity and frequency of wear. A shell cordovan strap can exceed 7-8 years. Regular maintenance (application of natural balms every 6-8 months) significantly extends longevity.
