FAQ
What is the lug width of the Hamilton Intra-Matic H38465501?
The lug width of the Hamilton Intra-Matic H38465501 is 20mm. This measurement is taken from the centre of one spring bar to the centre of the other, excluding the lugs themselves. It is a proportional standard that suits the 38mm case and grants access to a comprehensive catalogue of aftermarket artisanal straps.
Which strap is most suitable for the Hamilton Intra-Matic H38465501?
For the H38465501, we recommend a dark brown or black alligator for formal contexts, vegetable-tanned calf leather for daily wear with natural patina development, or a cotton-polyester NATO for smart-casual versatility. Black rubber is ideal for aquatic use whilst maintaining minimalist elegance.
How do I change the strap on the Hamilton Intra-Matic H38465501?
The strap is replaced by acting on the spring bars at the lug ends. Using a spring bar tool, gently press the spring bar to extract it from the lug, removing the old strap. Insertion of the new strap follows the reverse procedure: insert the spring bar into one lug seat, guide the strap, and secure the spring bar into the opposite seat. Proceed with care to avoid scratching the lugs.
Will a 20mm aftermarket strap be compatible with my H38465501?
Yes. Any strap with a 20mm lug width, regardless of brand and material, is compatible with the H38465501. Compatibility is guaranteed by the lug measurement: centre spring bar to centre spring bar. Always verify the measurement with your retailer prior to purchase.
How long does a leather strap last on the Hamilton Intra-Matic H38465501?
A quality artisanal leather strap, vegetable-tanned, develops patina within 6-12 months of daily wear. Structural durability depends on frequency of use and exposure to water and humidity: typically 3-5 years for well-maintained calf leather. Leather requires periodic cleaning and protection from excessive moisture to preserve longevity.
