Strap for Intra-Matic 38 Rose Gold / Grey

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.

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.

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.

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.

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.
