Strap for Speedmaster Teutonic SpeedyMoon Two Tone

The lug width of the Omega Speedmaster Moonwatch TA 345.0810 is 20 millimeters. This dimension is measured by positioning a digital caliper between the inner edges of the case lugs, excluding the case itself. It is the established standard for Speedmaster chronographs and is compatible with all straps designed for this measurement.

For the TA 345.0810 we recommend an alligator in dark shades (black, deep brown, navy blue) for maximum formal elegance, or vegetable-tanned calf for everyday versatility. For sports use, natural rubber or canvas NATO ensure durability and authenticity. The choice depends on the occasion and the desired visual contrast with the titanium-yellow gold combination.

The strap on the Omega Speedmaster Moonwatch TA 345.0810 is changed by removing the spring bars – small metal levers that slide into the case – using a spring bar tool or specialized instrument. Position the tool under the lug, compress the internal spring downward, and slide the lug out of the attachment. Insert the new 20mm strap by following the reverse path, ensuring the spring bars lock completely at both attachments.

Yes, any artisanal or commercial strap built with a 20 millimeter lug width is compatible with the TA 345.0810. However, we recommend choosing materials and construction that respect the aesthetic architecture of the Moonwatch – thickness between 3.5 and 4.5mm, precise stitching, and a robust deployant – to maintain visual cohesion and durability over time.

A quality leather strap – alligator, calf, shell cordovan – made with vegetable tanning and robust stitching, lasts an average of 3-5 years of daily use, varying based on sun exposure, humidity, rotation frequency, and personal care. Leather ages by developing a characteristic patina, increasing rather than decreasing its aesthetic value. Periodic protective treatment and proper storage significantly extend the strap's longevity.
