Strap for Speedmaster Date 38 Stainless Steel - Diamond / Brown

The lug width is 18mm. This measurement is specific to the compact 38mm case version and is measured by inserting a caliper into the cavities on the case shoulder. It is important not to confuse it with 20mm lugs: 18mm is the exact dimension to ensure correct aesthetic and functional pairing.

The best strap depends on usage: vegetable-tanned brown alligator combines elegance and durability for daily wear; shell cordovan is ideal for those seeking leather that develops patina over time; black calf with ivory stitching maintains the sporty DNA. For casual occasions, a steel grey nylon NATO is practical and reversible.

The Omega Speedmaster uses removable spring bars. Position the watch with the caseback facing upward, locate the pins under the lug using a magnifying glass, insert a spring bar tool under the shoulder to compress the internal spring and, once released, extract the pin. Attach the new strap by threading the pin into the side loops until it clicks. Proceed with caution to avoid scratching the case.

Any strap with an 18mm lug width is compatible. We recommend artisanal examples in vegetable tanning, shell cordovan or calf, where the reduced width does not compromise construction quality. Our milanostraps.it straps are customizable with initials, contrast stitching points and available made-to-measure with an 18-month warranty.

A high-quality artisanal leather strap lasts 3-5 years with daily use, developing natural patina and shrinkage over time. Durability depends on sun exposure, humidity and cleaning frequency. Shell cordovan ages better than other leathers; alligator requires maintenance every 18-24 months. With proper care, even examples over 10+ years old remain functional.
