Strap for Belluna Royal Gent Stainless Steel / Blue

The lug width of the Mido Belluna M024.507.16.041.00 is 20mm. This dimension is specific to the model and represents a deliberate design choice by Mido to maintain optimal proportions on the 41.30mm case. To verify this measurement precisely, use a digital calliper to measure the exact spacing between the lug attachment points.

The choice depends on usage context and personal preference. For formal elegance: cognac brown or black alligator with precious metal deployante. For daily versatility: vegetable-tanned calf leather in natural hues (brown, burgundy) that develop character over time. For practical durability and humid environments: Oxford canvas NATO or vulcanised rubber. All items in our catalogue are pre-measured to guarantee perfect fit.

Strap replacement requires two tools: a spring bar removal tool or a small nylon mallet. Position the watch on a soft surface with the lug side facing upwards. Locate the small opening on the lug shoulder: insert the removal tool and press gently downward to release the spring bar. Remove from both sides, then align the new strap and insert the spring bars until you hear or feel the click of engagement. If uncertain, our fitting service at Atelier Casati Milano is available by appointment.

Any strap with a 20mm lug width is technically compatible. Our dedicated 20mm strap collection features premium leathers (alligator, calf, shell cordovan), canvas NATO options, and vulcanised rubber. Each product is tested to ensure precise fit without play or forcing. We recommend avoiding generic mass-market products: quality selection significantly enhances the wearing experience.

Longevity depends on leather type and usage patterns. A calf strap with vegetable tanning in moderate daily use typically delivers 3-5 years of aesthetic service before replacement, though it remains wearable beyond that threshold. Premium alligator can last 5-8 years. Vulcanised rubber typically lasts 2-3 years. Proper maintenance significantly extends lifespan: monthly cleaning with damp cloth, leather balm application every 3-4 months, and dry storage conditions. Vegetable-tanned leather ages nobly rather than degrades.
