Frequently asked questions

What is the exact lug width of the Omega Speedmaster (Non-Moonwatch) 324.33.38.40.04.001?

The lug width is 20mm, measured internally between the two lug bars. This width is standard for the 324.33.38.40.04.001 model and ensures optimal proportions with the 38mm case diameter.

Which strap is best suited for the Speedmaster 38 324.33.38.40.04.001?

Brown alligator or shell cordovan are ideal for emphasizing the sunburst blue dial. For daily wear, vegetable-tanned calf or technical rubber offer practicality and durability. NATO remains the universal choice for versatility and quick changes.

How do you change the strap on an Omega Speedmaster 324.33.38.40.04.001?

Remove the 20mm internal lug bars using a dedicated tool or fine needle to push the lateral springs. Extract the bars, remove the old strap, position the new one, and reinsert the bars until the locking click. If inexperienced, consult a professional.

Is a 20mm aftermarket strap compatible with this Speedmaster?

Yes, any strap with a 20mm lug width is compatible with the 324.33.38.40.04.001. We recommend verifying the total length according to your wrist circumference and choosing straps from specialized suppliers to ensure quality and durability.

How long does a leather strap last on a watch like the Speedmaster 38?

A quality leather strap, such as alligator or shell cordovan, typically lasts 3-5 years with daily wear, developing a natural aging patina over time. Vegetable-tanned calf varies from 2-4 years depending on exposure to moisture and direct sunlight. NATO and rubber have longer lifespans (5-10 years).
