Frequently asked questions

What is the lug width of the Omega Speedmaster (Non-Moonwatch) 3519.50.00?

The lug width is exactly 20mm, measured between the centers of the upper and lower attachment pins. This is a specific dimension of the Speedmaster Reduced line and should not be confused with the 19mm of other chronographs. Precise measurement is essential for choosing a compatible strap.

What strap material do you recommend for the Speedmaster 3519.50.00?

Vegetable-tanned alligator is the ideal choice to enhance the racing character: the marked grain pairs perfectly with the case surfaces. Shell cordovan offers a more aristocratic and durable alternative. Vegetable-tanned calf is versatile and balanced. For sports use, nylon NATO or FKM rubber are practical and resistant.

How do I change the strap on my Omega Speedmaster 3519.50.00?

The strap is replaced using a spring bar tool or dedicated tool to extract the pins from the case attachment holes. Insert the pin into the upper hole, then push the strap toward the inside of the case to seat the lower pin. Verify that the pin is fully secured before wearing the watch.

Can I use an aftermarket 20mm strap on my Speedmaster 3519.50.00?

Yes, any strap with a certified 20mm lug width is compatible. It is essential that the width is precise: a 19mm strap would not ensure a solid attachment. Milano Straps offers 20mm straps specifically made for this model, with the option to customize material, color, and closure.

How long does a leather strap last on the Speedmaster 3519.50.00?

A quality leather strap (alligator, shell cordovan, calf) typically lasts 3-5 years with daily use, with variability depending on climate, wear, and maintenance. Vegetable tanning ages better than chrome tanning, developing a patina. Milano Straps offers an 18-month warranty and the option to regenerate the strap at the Casati Milano atelier.
