FAQ
What is the lug width of the Omega Speedmaster (Non-Moonwatch) 3511.50.00?
The lug width is 18mm. This measurement represents the distance between the inner edges of the two lugs on the case. It is important to verify it correctly to ensure compatibility with aftermarket straps.
Which strap is best suited for the Speedmaster 3511.50.00?
For this chronograph we recommend alligator in dark shades (blue, burgundy, black), vegetable-tanned calf leather that develops patina over time, or shell cordovan for durability. The choice depends on the use case: formal, everyday or sporty. A rubber or NATO strap is ideal if the watch remains a working instrument.
How to change the strap on the Speedmaster 3511.50.00?
Use a tool to remove the spring bars that hold the strap anchored to the lugs. Gently push the spring inward to release the strap. Position the new strap by aligning the holes with the lugs and compress the springs until they are fully engaged. If you lack experience, consult a professional.
Can I use an aftermarket strap on an Omega Speedmaster (Non-Moonwatch) 3511.50.00?
Yes, any strap with an 18mm lug width is compatible with the 3511.50.00. Always verify the measurement before purchase to avoid incompatibility. Online you will find customizable straps in leather, rubber and fabric ready to ship.
How long does a leather strap last on this Speedmaster?
A quality alligator strap lasts 3-5 years with daily use. Shell cordovan resists 5-7 years thanks to the compactness of its structure. Vegetable-tanned calf varies from 2-4 years depending on wear and exposure to moisture. Maintenance and seasonal rest extend durability.
