Strap for Speedmaster Professional Moonwatch Italia

The lug width of the Omega Speedmaster Moonwatch DA 145.0022 is 20mm. This standardization allows you to fit compatible straps from any manufacturer, provided the spring bar width is calibrated precisely at 20mm. You can verify this with a digital caliper by measuring the inner shoulder of the case or by consulting the official Omega booklet supplied with the watch.

For this two-tone configuration, polished black alligator offers maximum refinement, emphasizing the severity of the case. If you seek absolute longevity, shell cordovan (horseback leather) resists decades of use and develops a fascinating patina. For artisanal sensitivity, vegetable-tanned Tuscan leather develops a noble patina over time. An FKM rubber strap adds sports versatility if you use the Speedmaster in aquatic or marine environments.

The strap is changed by removing the spring bars (lugs pins) that connect the strap to the case lugs. Use a dedicated spring bar tool, available at any watch shop, or entrust the task to an authorized service center. The procedure requires delicacy to avoid scratching the case: position the spring bar horizontally, gently compress the internal spring with the tool, and extract the pin. Insert the new strap by reversing the process.

Absolutely yes. The NASA certification concerns the movement and case, not the strap. An aftermarket strap in alligator, shell cordovan, or quality vegetable-tanned leather does not compromise functionality or Omega warranty, provided it is fitted correctly to the 20mm lug width and without case modifications. Many collectors alternate straps to vary aesthetics depending on the occasion.

A quality artisanal alligator or shell cordovan strap guarantees 8-15 years of daily use before requiring replacement. Shell cordovan can last 20-30 years thanks to the structural density of the leather. Lifespan depends on frequency of use, humidity exposure, and maintenance: avoid prolonged perspiration in direct contact with the strap and allow it to dry completely after water exposure. FKM rubber straps have indefinite lifespan if not exposed to extreme temperatures exceeding 60°C.
