Strap for Speedmaster Michael Schumacher Stainless Steel / Black / Bracelet / The Legend Panda

The lug width measures 20mm. This anchor dimension is specific to the 3507.51.00 model and requires watch straps with corresponding lug width to prevent forcing or excessive play between the lugs and case. Always measure perpendicularly between the inner shoulders of the lugs.

On a professional stainless steel chronograph of 42mm, authentic alligator represents the premier aesthetic choice: the natural grain and brilliance amplify the contrast with the satin case. Alternatively, vegetable-tanned calf offers progressive patina and authentic aging character. Heavy canvas NATO is a pragmatic solution for sports and casual variation.

Remove the case from the original lugs using a dedicated tool (spring bar tool) or consult a watchmaker. Position the tool at the base of the anchor spring, apply perpendicular pressure to compress it, then extract the lug downward from its seat. Insert the new strap by crossing one spring first, then the other with fluid and controlled movement.

Yes, any strap with a 20mm lug width is compatible. Milano Straps offers a range of artisanal 20mm straps in alligator, calf, and premium leathers, customizable in sizes and thickness. Verify that the thickness does not exceed 4-5mm in the lug seat for optimal fitting.

A quality vegetable-tanned calf strap lasts 3-5 years with moderate daily use, developing characteristic patina. Alligator resists 5-7 years thanks to superior construction density. Durability depends on exposure to sweat, humidity, and mechanical wear. Casati Milano offers an 18-month warranty and restoration service to extend the life of your strap.
