Strap for Navy Watch Monaco / Stainless Steel / Superluminova

The lug width of the Laco 861804 is 18 mm. This width was specifically chosen to maintain the harmonious proportions of the 36 mm case. To verify compatibility, measure the distance between the two lateral lugs on the case: it must be exactly 18 mm.

For the Laco 861804, we recommend alligator straps with vegetable tanning for formal wear, natural calf leather for understated elegance, cotton-polyester NATO straps for sporty contexts, or FKM rubber for maximum durability. Your choice depends on intended use and aesthetic preference: the black lacquered dial pairs naturally with earthy tones (brown, cognac, sandy grey).

To change the strap, use a spring bar tool to remove the elastic pins connecting the strap to the case. Insert the tool's tip into the groove beneath the pin and gently push inward to release the lug. Once the old strap is removed, position the new one by aligning the pins with the case holes and press until you hear a click indicating secure fastening.

Yes, any strap with an 18 mm lug width is compatible with the 861804. On MilanoStraps, you will find a selection of artisanal leather straps (alligator, French calf), NATO straps, and rubber options, all available in 18 mm and customizable according to your colour and finish preferences.

The lifespan of a leather strap depends on construction quality and tanning method. An artisanal vegetable-tanned leather strap, worn daily, lasts 3-5 years before replacement is needed. Vegetable tanning develops an ennobling patina over time. Rubber straps have a longer lifespan (7-10 years), whilst cotton-polyester NATO straps remain functional for 5-6 years.
