Frequently asked questions

What is the lug width of the Mido Multifort M047.507.17.041.00?

The Mido Multifort M047.507.17.041.00 features a lug width of 12mm. This dimension is determined by the geometry of the soldered bayonet attachments on the case. It is crucial to respect this exact measurement to prevent lateral play or stress on the attachment points. Measuring from the outer point of one lug to the other, you should obtain exactly 12mm.

What type of strap is most suitable for the Mido Multifort M047.507.17.041.00?

For the 40mm Multifort, vegetable-tanned calf leather in cognac brown represents the most versatile and elegant choice, developing natural patina over time. For lasting luxury, full-scale alligator offers superior moisture resistance. If you seek sportiness, a cotton-polyester NATO or FKM rubber guarantees daily practicality. The buckle should be steel with a deployante for user comfort. We always recommend selecting straps specifically designed for 12mm from Milano Straps' collection.

How do I change the strap on this watch?

The Multifort M047.507.17.041.00 features bayonet attachments: place the watch on a soft surface, gently grasp the case and push the strap upwards to disengage it from the seat. Repeat on the other side. To mount the new strap, align the ends with the attachments and press downwards until you hear the closure click. Do not force: a correctly calibrated 12mm lug enters easily without constraint. The change takes less than one minute.

Can I use aftermarket straps compatible with the Mido Multifort?

Absolutely. Milano Straps offers high-quality artisanal straps specifically calibrated for the 12mm lug width. These products maintain the width and thickness specifications necessary for a perfect fit on the bayonet attachments. Always verify that the strap is designated for 12mm: incorrect use of 14mm or 16mm straps results in play or damage to the attachments. Online personalisation allows you to choose colour, material and buckle style according to your preferences.

How long does a leather strap last on the Mido Multifort?

A vegetable-tanned calf leather strap offers longevity of 4–6 years with daily use and ordinary maintenance (monthly cleaning, protection from prolonged moisture). Shell cordovan, being denser, can exceed 8 years. Alligator lasts 6–7 years thanks to the fibrous structure of reptile skin. Longevity depends on perspiration, climate and frequency of use. We recommend alternating straps when possible, allowing complete drying between uses. Milano Straps can replace worn straps while maintaining the same attachments.
