Ulysse Nardin
Marine 1183— lug 21mm

The lug width of the Marine 1183 is 21mm. This width is specifically engineered for this model and ensures harmonious proportions with the 42mm case. To verify compatibility, measure the distance between the lugs on your case: the measurement in millimetres corresponds precisely to the strap width required.

For the Marine 1183, we recommend Mississippi alligator in cognac or satin black tones, which enhance the nautical and elegant aesthetic of the stainless steel case. Alternatively, vegetable-tanned calf offers a captivating patina development over time, whilst a NATO strap provides a sporty yet versatile solution. For daily marine use, synthetic rubber ensures resistance to salt water and superior durability.

To change the strap, you will need a spring bar tool and a small plastic lever. Place the watch on a soft surface, locate the two lateral pins at the lugs, and use the spring bar tool to extract them gently. Remove the old strap, align the new strap with the lugs, and reinsert the pins. If you are inexperienced, consult a professional watchmaker to avoid damage to the case.

Yes, any aftermarket strap with a 21mm lug width is compatible with the Marine 1183, provided the construction quality is appropriate. Avoid economical straps with poor-quality leather or defective finishing. A quality aftermarket alligator, calf, or NATO strap maintains correct proportions and offers an elegant alternative at lower prices than official Ulysse Nardin straps.

The lifespan of a leather strap depends on usage and maintenance. A quality artisanal alligator strap with vegetable tanning typically lasts 3–5 years with daily wear. Calf leather lasts 2–4 years with regular use. Frequent cleaning, exposure to perspiration and humidity, and protection from heat sources extend useful life. Premium leather straps, when properly maintained, can last longer than 5 years.
