Mido
Belluna M024.630.36.041.00— lug 21mm

The lug width of the Mido Belluna M024.630.36.041.00 is 21 mm. This measurement is critical for selecting compatible aftermarket straps: any strap intended for this case must have exactly 21 mm width between the two spring bars that sit in the integrated lugs.

For the Belluna, we recommend Italian vegetable-tanned leather straps (Tuscan or Barenia) for formal daily wear, or Swift leather for greater water resistance. Mississippi alligator is the luxury choice if you desire pronounced grain texture and a patina that develops nobly over time. NATO straps in dense weave complement the watch's brushed stainless steel aesthetic.

Remove the watch from its original strap using a strap removal tool. Insert the tip into the lateral access hole of the lug and extract the spring bar outward. Once both lugs are freed, insert the new strap's spring bars into the lugs, ensuring they seat perfectly without play. The Belluna's lug depth is approximately 4.5 mm: verify that your new strap is not too thick for this geometry.

Yes, provided the lug width is exactly 21 mm and the strap thickness does not exceed 4.5–5 mm at the spring bar attachment points. A well-designed strap sized for this measure installs without issue and does not compromise the case. We always recommend verifying the manufacturer's specifications before purchase.

A quality leather strap (Italian vegetable-tanned, Swift, or alligator) maintains structural and aesthetic integrity for 3–5 years with moderate daily wear. Longevity depends on sun exposure, humidity, and cleaning frequency. Barenia or alligator straps age visibly, developing a noble patina. We recommend periodic rotation with other straps to extend overall service life.
