Strap for Speedmaster Date 38 Stainless Steel - Diamond / Green / Bracelet

The lug width is 18mm. Unlike the 42mm Speedmaster Moonwatch which features 20mm lugs, this 38mm model maintains the 18mm width, a specific construction characteristic inherited from Speedmasters of the Seventies. Always verify the measurement by removing the original strap and measuring the distance between the inner spring bars.

The best strap depends on use and personal style. For formal elegance we recommend brown alligator with vegetable tanning; for authentic sport wear, a thin canvas grey or black NATO; for a long-term investment, shell cordovan with vegetable tanning that develops a caramel patina. The lug-to-case ratio (18mm on 38mm) favors straps with balanced texture, not excessively thick.

Remove the watch from your wrist. Locate the small spring bars on both sides of the case, beneath the lugs. With a dedicated tool—removal pin or fork tool—press the spring bar retention mechanism downward while simultaneously sliding the lug out of the suspension. Repeat on the opposite side. Insert the new 18mm strap by aligning the bars, ensuring they click into position. If uncertain, contact an Omega service center or specialized strap atelier.

Yes, provided the lug width is exactly 18mm. Milanostraps offers custom-made straps with choice of materials (alligator, shell cordovan, calf, NATO, rubber) and is compatible with the 324.18.38.50.60.001 reference. Caution: many 'Speedmaster' straps on the market feature 20mm lugs, incompatible with this reference. Always verify before purchase.

A quality leather strap (alligator or shell cordovan with vegetable tanning) typically lasts 3-5 years of daily wear, provided correct maintenance: avoid direct water, do not excessively bend the strap at rest, clean with a soft dry cloth. Shell cordovan, thanks to its dense fibrous structure, lasts longer than most calf leathers. The Casati Milano atelier offers an 18-month warranty on every strap and a rapid replacement service.
