Strap for Executive Carbon

The lug width of the Ulysse Nardin Executive 3715-260/CARB is 20 mm. This measurement represents the linear distance between the two spring bar attachments located on the case lugs in carbon composite, and it determines the geometric compatibility of any replacement strap. You can verify this dimension independently using a digital calliper by measuring the space between the internal fixing rings.

The best strap depends on intended use and aesthetic preference. For formal wear, we recommend alligator with fine grain texture in cognac brown or black tones, which creates sophisticated contrast with the carbon case. For sporting use, a charcoal grey NATO strap or synthetic rubber offers comfort and versatility. Vegetable-tanned calf leather straps, ageing naturally over time, develop a patina that harmoniously dialogues with the contemporary materiality of the carbon.

Changing the strap requires the use of a dedicated spring bar tool (strap removal tool). Position the tool inside the case lug to compress the internal spring of the attachment, enabling the bar to be extracted. Repeat for both sides. Insert the new strap's bars into the attachments, verifying that the retention spring clicks correctly into position. This operation demands precision, and if you lack experience, it is advisable to entrust the task to a specialised watchmaker.

Yes, any strap with a 20 mm lug width is compatible with the 3715-260/CARB. Milano Straps offers an extensive range of handcrafted straps in this size, manufactured from carefully selected materials (alligator, calf, NATO, rubber) and fully customisable to individual specifications. Geometric compatibility is guaranteed by this international standardisation, permitting endless aesthetic solutions without constructive compromise.

The lifespan of a leather strap depends on material type and intensity of use. A quality alligator with vegetable tanning has an estimated longevity of 5-7 years in regular use, developing a distinctive patina over time that increases its appeal. Vegetable-tanned calf leather presents similar durability, with a texture that softens naturally with age. Environmental conditions (humidity, sun exposure), frequency of wear, and routine care (gentle cleaning) significantly influence the preservation of leather over time.
