Strap for Speedmaster Date 40 Stainless Steel / White / Bracelet / Olympic Timeless

The lug width of the Omega Speedmaster 3516.20.00 is 20mm. This dimension is precise and fundamental to maintaining the balanced proportions of the 40mm case design. Measure the lug width with a digital caliper positioned between the two lug poles without including the spring thickness.

For the 3516.20.00 we recommend Nile crocodile with vegetable tanning (granular texture that dialogues with the racing design), vegetable-tanned calf (soft and versatile), shell cordovan (durability and evolved patina) and technical fabric NATO (sporty robustness). The ideal thickness is 4-4.5mm to ensure rigidity without overloading the lugs.

Remove the caseback with a dedicated tool. Locate the springs that connect the lugs to the case. Gently extract the current strap by disengaging the springs. Insert the new strap by aligning the lugs to the designated holes and reposition the springs until a sharp click. Contact a specialized workshop if you lack experience.

Yes, any 20mm strap is mechanically compatible with the 3516.20.00. However, the choice of material and style must respect the aesthetic balance of the case: crocodile and vegetable-tanned calf maintain the original racing elegance, while NATO adds a more pronounced sporty character.

A high-quality artisanal crocodile or calf strap lasts 5-7 years with daily use, developing a characteristic patina over time. Shell cordovan can last 10+ years thanks to its natural hardness. Longevity depends on the tanning method, thickness (4.5mm is ideal), care (avoid prolonged water exposure) and frequency of use. Rotating with other straps extends the life of each one.
