Strap for All Dial Chronometer Stainless Steel / IBA

The lug width of the Mido All Dial M8340.4.B3.11 is 24 millimetres. This width is proportionate to the 42-millimetre case diameter and represents the standard for this specific reference. Measure the distance between the lugs with callipers to verify compatibility before purchasing an aftermarket strap.

For the Mido All Dial M8340.4.B3.11, straps in vegetable-tanned leather, shell cordovan, or NATO and vulcanised rubber are ideal. The choice depends on intended use: leather is recommended for formal settings and develops a noble patina over time; technical straps (NATO and rubber) are preferable for daily or sporting activities. All must feature a 24-millimetre lug width.

Changing the strap on a Mido All Dial M8340.4.B3.11 requires a specific tool (spring bar tool) or professional support from a watchmaker. If the watch features a deployante clasp, first remove it from the old strap. Subsequently, use the bar to extract the spring bars that secure the strap to the lugs. Finally, insert the new strap in the same position, ensuring it respects the correct 24-millimetre lug width.

Yes, it is possible to use aftermarket straps provided they strictly respect the 24-millimetre lug width. Milano Straps offers a compatible strap collection in leather, NATO, and rubber, all proportioned for this model. Always verify the width and thickness of the lug attachment before purchase to avoid dimensional inconsistencies.

A quality leather strap on a Mido All Dial M8340.4.B3.11, subjected to moderate use (4-5 days per week), has an average lifespan of 4-6 years. Longevity depends on tanning type and maintenance: a vegetable-tanned or shell cordovan strap can extend to 8-10 years if regularly cared for with specific creams. Periodic rotation with other straps significantly prolongs the life of each one.
