Strap for Speedmaster Reduced Ladies Stainless Steel / Diamond / MOP / Green / Bracelet

The lug width of the Speedmaster Reduced 3535.72.00 is 18mm. This dimension is specific to this model and should be measured between the inner edges of the spring bar pins perpendicular to the lug itself. Always verify this measurement before ordering a strap to avoid incompatibility.

For the Speedmaster Reduced 3535.72.00 we recommend black alligator for a formal and contemporary aesthetic, vegetable-tanned brown calf for those who prefer a patina that evolves over time, or cordovan for those who want to transform it into an evening watch. If you use the watch daily, a 200 denier nylon NATO maintains the sporty aesthetic without compromising durability.

Use a spring bar tool to gently push the spring bar pins inward, releasing the old strap. Position the new strap (18mm size) under the pins, then release the tool to allow the pins to snap into place. Verify that the strap is centered and properly secured on both sides before wearing the watch. If you are unsure, consult a professional watchmaker.

Yes, any strap with an 18mm lug width is compatible with the Speedmaster Reduced 3535.72.00, provided the spring bar pins have the correct diameter (typically 1.5mm or 1.8mm for this model). Always check the strap specifications before purchase. Custom straps from Casati Milano guarantee full compatibility and superior construction quality.

A quality leather strap (alligator, calf, cordovan) has an average lifespan of 4-6 years with daily use and proper care. Longevity depends on environmental humidity, frequency of use, and maintenance (avoid prolonged immersion, clean regularly with a soft cloth). Casati Milano straps include an 18-month warranty and can be refurbished or replaced at the atelier.
