Strap for Diver Chronometer Tourbillon Titanium / Black / Yoshida

The lug width is 20mm. This measurement is taken perpendicular to the lug holes. When ordering a compatible strap, ensure it is explicitly declared as 20mm to guarantee correct fit without excess play or tension.

For this titanium model we recommend natural alligator with vegetable tanning for maximum aesthetic contrast, vegetable-tanned calf leather for chromatic evolution over time, cordura NATO fabric for breathability, or FKM rubber with deployante clasp for actual diving and humid environments. Selection depends on actual use and personal aesthetic preference.

The Diver 1283-170LE-7M/92-J.1 features standard spring bars between the lugs. To change the strap: gently remove the existing spring bar using a watchmaker's spring bar tool, slide out the old strap from the lugs, insert the new strap through the lugs ensuring proper alignment, and secure the spring bar. If you prefer to avoid DIY, consult a qualified watchmaker.

Any strap with a 20mm lug width is compatible with this model. On milanostraps.it you will find a dedicated selection of 20mm straps in alligator leather, calf, NATO, and technical rubber, all tested for compatibility and build quality against Ulysse Nardin standards.

Lifespan depends on material and usage. An alligator or vegetable-tanned calf strap typically lasts 3-5 years with daily wear, with natural chromatic evolution over time. An FKM rubber strap can last 5-7 years since it is chemically inert. Factors such as humidity, temperature, and wearing frequency significantly influence longevity.
