Frequently asked questions

What is the lug width of the Omega Speedmaster (Non-Moonwatch) 326.30.40.50.11.001?

The lug width is 19mm. This Omega standard is found on 40mm cases with integrated chronograph. The lug depth (from top to bottom of the case) is approximately 20mm, an important element for selecting straps with appropriate thickness (maximum 4mm thickness).

What is the best strap for the Omega Speedmaster 326.30.40.50.11.001?

American alligator with vegetable tanning is the preferred choice: the large grain imparts gravitas to the traffic black dial, while the softness of the leather elegantly contrasts with the brushed finish of the case. Box calf with vegetable tanning represents a less demanding alternative with natural aging over time.

How do I change the strap on the 326.30.40.50.11.001?

The strap is secured to the lugs via screw-down spring bars. You will need a spring bar tool to remove the pins, extract the old strap and insert the new one, aligning it perfectly with the holes. Verify that the spring bar is properly positioned before final tightening to avoid damaging the lugs.

Are there aftermarket straps compatible with the Omega Speedmaster 326.30.40.50.11.001?

Yes, MilanoStraps offers a complete collection of 19mm customizable straps in sizes, colors, initials and stitching thread. All are compatible with the 19mm lugs of the 326.30.40.50.11.001 and crafted in superior quality leathers according to artisanal standards.

How long does a leather strap last on the Omega Speedmaster 326.30.40.50.11.001?

A strap in alligator or calf with vegetable tanning, subject to regular rotation (not worn on consecutive days) and appropriate maintenance, lasts 5-7 years before requiring replacement. The natural aging of the leather is part of the conscious use experience, not a defect.
