Frequently asked questions

What is the exact lug width of the Ulysse Nardin Executive 3713-260-3/BLACK?

The lug width of the Ulysse Nardin Executive 3713-260-3/BLACK is 20 mm. This measurement indicates the width of the case lug where the strap attaches, measured between the external points of the lug. All straps compatible with this width fit the model perfectly. To verify compatibility, use a digital calliper to measure the external width of the lug on your case.

Which strap is recommended for the 3713-260-3/BLACK model?

For the Ulysse Nardin Executive 3713-260-3/BLACK, we recommend straps in black or dark grey alligator to maintain aesthetic coherence with the titanium and ceramic case. A refined alternative is calf leather with vegetable tanning in havana or cognac tones. For a more sporting interpretation, navy NATO or rubber with ridged texture enhances the chronograph character without compromising versatility.

How do I replace the strap on my Ulysse Nardin Executive 3713-260-3/BLACK?

To replace the strap on the 3713-260-3/BLACK, use a spring bar tool to remove the lug pins. Position the tool in the small slot at the end of the pin, apply gentle inward pressure to compress the internal spring, then extract the pin. Next, thread the new 20 mm lug width strap and reinsert the pins. We recommend performing this operation with care to avoid scratching the case.

Are Milano Straps aftermarket straps compatible with my Executive?

Yes, all 20 mm straps in the Milano Straps catalogue are compatible with the Ulysse Nardin Executive 3713-260-3/BLACK. Our handcrafted straps are manufactured with construction tolerances that guarantee perfect fit to lugs of this width. Each piece is packaged with soft fabric passants to protect the case and arrives ready for installation.

How long does a leather strap last on the 3713-260-3/BLACK model?

The lifespan of a leather strap depends on the type of tanning and daily use. Vegetable-tanned alligator maintains structural integrity for 4-6 years with moderate wear, developing a fascinating patina over time. Calf leather has similar longevity, whilst shell cordovan, if treated with proper care, can exceed 7-8 years. Exposure to excessive moisture, perspiration and prolonged direct sunlight accelerates ageing. We recommend rotating multiple straps to distribute wear and periodically applying a quality leather conditioner.
