Frequently asked questions

What is the lug width of the Ulysse Nardin Marine 1193-310LE-0A-175/1B?

The lug width of the Ulysse Nardin Marine 1193-310LE-0A-175/1B is 21mm. This measurement is taken by placing a digital calliper between the horizontal pins of the lug suspension, measuring from the internal base of one lug to the other. A 21mm lug width is a refined specification requiring bespoke straps, excluding mass-produced industrial alternatives.

Which strap is recommended for the Ulysse Nardin Marine 1193-310LE-0A-175/1B?

Recommended straps vary according to intended use and personal aesthetic preference. Alligator leather (cognac brown or black) is the formal choice for classical contexts; vegetable-tanned calf develops natural patina and distinctive character over time; shell cordovan guarantees maximum durability and structural integrity; NATO in grey-slate or black shifts the narrative toward pragmatic-sportive registers; technical rubber is the engineered solution for humid environments or intensive activity.

How do I change the strap on a 42mm Ulysse Nardin with 21mm lugs?

Position the watch on a watchmaker's hand rest with protective padding. Using a spring bar removal tool, gently depress the horizontal pin from one side of the lug, allowing it to slide out of its seat. Repeat on the opposite side. Once the old strap is freed, thread the new strap by aligning its pins into the horizontal axes. The procedure requires 2-3 minutes and zero force application.

Is there a quality aftermarket strap compatible with the 1193-310LE-0A-175/1B?

Yes. Milanostraps.it stocks bespoke leather straps in 21mm lug width—alligator, calf, shell cordovan—as well as NATO and technical rubber options, all specifically constructed for this lug specification. Every strap is customisable in colour and finish, guaranteeing perfect mechanical compatibility with the suspension pins.

What is the average lifespan of a leather strap on the Ulysse Nardin Marine 1193-310LE?

A quality leather strap (alligator, vegetable-tanned calf, or shell cordovan), worn 4-5 days weekly, maintains structural integrity for 4-6 years. Lifespan depends on ambient humidity, cleaning frequency, and wear intensity. Shell cordovan resists degradation longer; vegetable-tanned calf develops visible patina within the first year. Maintenance with dedicated balm conditioner extends useful life by 12-18 months.
