Frequently asked questions

What is the lug width of the Omega Speedmaster (Non-Moonwatch) 326.30.40.50.01.002?

The lug width is 19mm. This measurement is essential for selecting the correct aftermarket strap. You can verify it by extracting the spring bar from the lugs and measuring it with a millimeter ruler. 19mm straps ensure precise integration with the case without slipping.

What strap material do you recommend for this model?

For the Speedmaster 326.30, we recommend three solutions: alligator for formal elegance, vegetable-tanned calf for natural aging and dialogue with the brushed steel case, and NATO for daily sports practicality. The choice depends on use: formal rotation, technical use, or casual versatility.

How do you change the strap on the Omega Speedmaster 326.30.40.50.01.002?

Extract the spring bar from one side using a dedicated spring bar tool or a small flat instrument. Remove the old strap, position the new 19mm strap, and reinsert the spring bar into its seats. Verify that it is securely fastened before wearing the watch. If you are unsure, contact a professional watchmaker.

Are 19mm straps sold online compatible with the 326.30 model?

Yes, all straps with 19mm lug width are compatible. However, ensure that the supplier clearly specifies this measurement and that the strap is made to quality standards (thickness, finish, stitching). At Casati Milano you will find certified and customizable straps for this model.

How long does a leather strap last on a chronograph like the Speedmaster 326.30?

Durability depends on use and material: quality alligator resists 3-5 years with rotation, vegetable-tanned calf 2-4 years with accelerated daily wear. Structured rubber lasts 5-7 years. Casati Milano guarantees 18 months on all artisanal straps, but with proper maintenance (controlled humidity, protection from sun) longevity extends significantly.
