The Marine 1553-155LE-3/E2-ART, seen from the bench

The Ulysse Nardin Marine 1553-155LE-3/E2-ART is a contemporary evolution rooted in Swiss maritime chronometric tradition. Housed in a 44mm brushed stainless steel case, this timepiece features the UN-155 caliber with drum chronograph column, complications including hours, minutes, small seconds, date, and regatta selector. The 20mm lug width accommodates structured straps while maintaining balanced proportions, reflecting the watchmaking heritage of Le Locle's manufacture without aesthetic compromise.

Frequently asked questions

What is the lug width of the Ulysse Nardin Marine 1553-155LE-3/E2-ART?

The lug width is 20mm. This measurement accommodates structured artisanal straps, from vegetable-tanned leather to shell cordovan, as well as technical rubber solutions. The 20mm size represents an intermediate standard that preserves the aesthetic proportion of the 44mm case whilst enabling multi-layer strap construction.

Which strap is most suitable for the Ulysse Nardin Marine 1553-155LE-3/E2-ART?

We recommend alligator straps with fine grain (luxury option) or calf leather with vegetable tanning (heritage-durability balance). Fine-grained alligator emphasises case geometry, whilst vegetable-tanned calf conveys constructive solidity. For intensive aquatic use, consider vulcanised rubber with vegetable-tanned leather lugs and keeper.

How do I change the strap on the Marine 1553-155LE-3/E2-ART?

Strap replacement requires lug pin extraction using an appropriate tool (spring bar tool or precision screwdriver). Position the watch on a soft surface, access the case shoulders, and remove the pins by applying uniform pressure. Install the new strap, aligning the lugs to the holes: verify absence of lateral play before wearing.

Is an aftermarket strap compatible with the Marine?

Yes. Any strap with 20mm lug width is compatible. We recommend Italian-made artisanal straps, where excellence in leather craftsmanship and deployant clasp construction ensures structural reliability and aesthetic patina development over time.

What is the lifespan of a leather strap for this watch?

A quality vegetable-tanned leather strap, subject to ordinary maintenance (saltwater protection, biannual conditioning), guarantees 3-4 years of daily use before replacement is necessary. Durability depends on usage intensity and environmental humidity management. Alligator straps offer greater longevity (5+ years).
