Strap for De Ville Co-Axial 41 Chronograph Stainless Steel / Black

The lug width of the De Ville 4841.50.31 is precisely 16 millimetres. This measurement must be strictly respected when choosing an aftermarket strap: 18mm straps will be too wide and will not fit into the lugs, while 14mm straps will leave excessive play. Correct measurement is performed with a digital calliper, measuring the internal space between the two lugs of the steel case, perpendicularly.

For the De Ville 4841.50.31, alligator represents the noblest and most formal choice, with regular grain that perfectly complements the brushed steel. Shell cordovan with vegetable tanning offers a natural patina that ages elegantly over time. A burgundy or black calf with steel deployant is ideal for those seeking elegant everyday versatility. For summer options, a grey pearl silk NATO or FKM rubber allow seasonal rotation while maintaining the formal profile.

Changing the strap on the De Ville 4841.50.31 requires the use of a spring bar tool and caution. Position the watch on a soft surface, locate the small hole on the inner part of the lug, insert the spring bar tool to compress the internal spring, then gently extract the original attachment bar. Repeat the process on the other side. Insert the new strap following the reverse path, ensuring that the spring is centred and the strap is secure. If you are not experienced, entrust the work to an Omega service centre or a specialised atelier such as Casati Milano.

Yes, 16mm aftermarket straps are fully compatible with the De Ville 4841.50.31. However, compatibility requires precise construction: the strap must respect exactly the 16mm width and attachment geometry. On milanostraps.it you will find a selection of 16mm straps designed for this model, with the possibility of customisation in leather, size and stitching. For a bespoke experience, the Casati Milano atelier creates custom straps with personal choice of leathers.

A quality natural leather strap on a De Ville has a variable lifespan: on average, with moderate daily use, 3-5 years for a standard calf, up to 7-10 years for a vegetable-tanned shell cordovan thanks to its intrinsic resistance and ability to age nobly. The lifespan depends on frequency of use, climatic conditions (humidity and sun damage leather), and maintenance (avoid immersion in water, apply protective balms 2-3 times a year). Alligator tends to last longer than calf, developing a prestigious patina over time. Casati Milano straps include an 18-month warranty and can be regenerated through specialised professionals.
