Frequently asked questions

What is the lug width of the Blancpain Villeret 6640-1127-MMB?

The Blancpain Villeret 6640-1127-MMB features a 22mm lug width. This dimension is consistent with the 40.30mm case diameter and ensures balanced optical proportions. The 22mm width is a manufacturer specification, and it is important to verify it before purchasing an aftermarket strap.

Which strap material is most suitable for this model?

For the Villeret 6640-1127-MMB, Mississippi alligator in dark shades (midnight blue, black, smoky brown) is the most coherent choice with the watch's classical and refined aesthetic. Vegetable-tanned calf leather and shell cordovan are valid alternatives for those preferring a different texture. FKM rubber is the functional option for less formal daily wear.

How do you change the strap on a Blancpain Villeret?

The strap is removed using a spring bar tool (an implement with flat ends) to disengage the small metal springs (spring bars) that secure the strap to the case lugs. The process is straightforward: insert the tool tip under the spring bar, lever gently until it releases from its seat, and remove the strap. To install a new strap, reverse the procedure by aligning the strap holes with the lugs and ensuring the spring bars click into position.

Is an aftermarket 22mm strap compatible with the 6640-1127-MMB?

Yes, any strap with a 22mm lug width is mechanically compatible with the Villeret 6640-1127-MMB. However, to preserve the aesthetic and proportions originally designed by Blancpain, it is advisable to choose straps of equivalent quality in noble materials (premium leather, technical rubber of high quality) and discreet colours that do not visually compete with the stainless steel case.

How long does a leather strap last on a daily-wear watch?

A premium leather strap (alligator, calf, shell cordovan), if subjected to regular daily use and maintained with minimal care (periodic cleaning, protection from excessive moisture), has an average lifespan of 3-5 years. The 22mm lug width on a watch like the Villeret is less subject to stress compared to sports models, tending to preserve strap integrity. The patina that develops over time is part of the leather's natural ageing and does not indicate deterioration.
