Strap for Speedmaster Date 40 Red Gold / Black

The lug width is 19mm. This measurement is specific to the Speedmaster in a 40mm case and is essential for identifying compatible straps. To verify it, measure the external space between the lugs (inner edge to inner edge): it must be precisely 19mm.

For a rose gold Speedmaster, we recommend Porosus alligator in cognac or dark brown, which amplifies the warmth of the case. Alternatively, English calf leather in vegetable tanning or burgundy Hungarian cordovan, which develops natural patina over time. These materials authentically complement rose gold, while synthetics would be inadequate.

The strap is anchored to the lugs via spring bars. Use a dedicated tool (spring bar remover) to compress the pin and extract the old strap. Insert the new one by aligning the spring bar, then release. If you are unsure, consult a competent watchmaker to avoid damaging the lugs.

Yes, bespoke 19mm straps for this Speedmaster are available online and customizable. MilanoStraps offers a selection of alligator, cordovan and calf leather crafted to measure, with options for grain, color and thread. The Casati Milano atelier also creates fully bespoke models with personal consultation.

A bespoke alligator or cordovan strap lasts 3-5 years with daily use, provided occasional maintenance is performed (avoid standing water, dry quickly after moisture exposure). Relined calf leather, more delicate, has similar longevity but requires greater care. Standard warranty is 18 months; MilanoStraps and Casati Milano offer support to extend the strap's lifespan.
