Mido
Belluna M024.307.33.036.00— lug 16mm

The lug width of the Mido Belluna M024.307.33.036.00 is precisely 16mm. This measurement represents the vertical distance between the two spring bars that attach the strap to the case. Before purchasing an aftermarket strap, it is essential to verify that the width corresponds exactly to 16mm, using a digital calliper or a millimetre ruler to measure the distance between the two metal lugs on the case.

The Belluna, with its 33.40mm case and classical identity, accommodates multiple strap solutions. A black or brown alligator strap enhances the formal and understated character of the model. Alternatively, a vegetable-tanned leather strap offers aesthetic versatility and develops natural patina over time. For a more casual approach, a cotton NATO fabric strap or an FKM rubber strap provides practicality and ease of maintenance without compromising the timepiece's elegance.

Strap replacement is accomplished via the two spring bars (elastic bars) anchored to the lug attachments on the case. Using a dedicated tool—a spring bar tool or a small flat blade—gently press one spring bar downward, creating a gap sufficient to remove the strap from its slot. Repeat on the other side. To fit the new strap, align the strap's lug hole with the case attachment, insert the spring bar and release it slowly, ensuring the strap is securely locked. Operate with care to avoid damaging the case.

Any strap manufactured for a 16mm lug width is compatible with the Belluna M024.307.33.036.00. Quality aftermarket straps—in alligator, leather, shell cordovan, NATO or rubber—are available from specialist manufacturers such as Milano Straps, which offers curated selections, customisable options and ready for dispatch. Always verify that the strap is explicitly specified as compatible with 16mm lug width.

The durability of a leather strap depends on material quality, conditions of use and maintenance. A quality alligator or leather strap can last 3-5 years with daily wear, progressively developing characteristic patina. A shell cordovan strap, owing to its density and resilience, may last 5-7 years or longer. Longevity increases if the strap is protected from excessive humidity, not exposed to prolonged perspiration and occasionally cleaned with a soft cloth. FKM rubber straps are more durable over time and do not require the same maintenance; they typically last 5-10 years before showing signs of degradation.
