The Marine 1182-310/42, seen from the bench

The Ulysse Nardin Marine Chronograph 1182-310/42 is a 42mm chronograph in 18-karat rose gold, featuring the proprietary UN-118 manual-winding movement with column-wheel organization. The round rose gold case with convex lines offers hours, minutes, small seconds, date, and power reserve indicator. Lug width is fixed at 21mm, requiring specific non-standard straps. Dark brown alligator leather or vegetable-tanned calf with tight grain are recommended materials for this model.

Frequently asked questions

What is the exact lug width of the Ulysse Nardin Marine 1182-310/42?

The lug width is 21mm. This dimension is binding for strap compatibility: a 20mm lug would result in play, whilst a 22mm lug would not fit into the case attachments. Measure with a digital calliper, positioning the tip precisely between the inner vertices of the lug.

Which strap material suits the Ulysse Nardin Marine 1182-310/42 in rose gold best?

Natural alligator in dark brown tones offers the finest aesthetic balance: the crocodilian scale texture enhances the rose metal without chromatic conflict, and the patina improves with time. Alternatively, vegetable-tanned calf leather with tight grain assures longevity (5–7 years) and authentic ageing. For sporting contexts, cordura NATO or structured FKM rubber ensures technical functionality whilst maintaining the gravitas of the rose gold case.

How do I change the strap on the Marine 1182-310/42?

The strap attaches via a straightforward lug system: insert the strap into the lateral case attachments, verifying that the passant is fully seated. If the strap does not enter, confirm the width is exactly 21mm. For straps with a deployante, press the lateral button to detach. For open buckle designs, manually extract the passant from the attachment. No specialist tools are required.

Can I use an aftermarket 21mm strap on my Marine 1182-310/42?

Yes, any strap with a 21mm lug width is compatible. Milano Straps offers artisanal leather straps of superior quality (alligator, vegetable-tanned calf, shell cordovan), NATO bands, and FKM rubber. All are customisable and ship ready. Compatibility is guaranteed by the binding lug width: 21mm ± 0.5mm.

How long does a leather strap last on the Ulysse Nardin Marine 1182-310/42?

A natural alligator strap typically lasts 5–7 years with moderate daily wear. Vegetable-tanned calf, owing to fibre structure, may last 6–9 years if kept dry. Longevity depends on ambient humidity (elevated moisture shortens life) and frequency of use. An FKM rubber strap does not age and retains its properties virtually unchanged for 10+ years, making it ideal for marine or saline environments.
