Strap for Navy Watch Navy / Stainless Steel / Creme

The Laco Navy Watches 861614 features an 18-millimetre lug width. This measurement represents the diameter of the bar that passes through the case lugs and accommodates the strap attachment. All compatible straps must be punched or fitted with internal keepers calibrated to exactly 18 millimetres to ensure a perfect fit.

For the Laco Navy Watches 861614, straps in vegetable-tanned calf leather, alligator, woven NATO or rubber are recommended, depending on intended use. A calf strap in brown or navy blue emphasises the vintage and military character of the model, whilst a NATO offers tactical practicality. Rubber proves ideal for humid or sporting environments, maintaining the aesthetic purity of the case.

Changing the strap on a watch with 18-millimetre lugs requires a spring bar tool, a two-pronged implement with grooved slots. Insert the fine tip into the keeper's slot, press gently to retract the spring bar latch and lift the strap. Repeat from the opposite side. To install the new strap, align the holes with the same bar, insert the spring and lower the strap until fully anchored. The operation takes just minutes.

Yes, it is possible to use aftermarket straps provided they are calibrated to 18 millimetres. Milano Straps offers a dedicated collection of artisan straps in leather, NATO and rubber, all tested to guarantee mechanical and aesthetic compatibility with the 861614 model. The 18mm lug width is a recognised standard, facilitating selection amongst numerous options.

The durability of a leather strap depends on the tanning method employed, exposure to humidity and sunlight, and frequency of wear. A calf strap with vegetable tanning, maintained with natural oils periodically, can last three to seven years. Alligator leather, being more robust, may reach ten years. The 18mm lugs of the 861614 model are not subject to anomalous mechanical stress, allowing the strap to age according to its natural characteristics.
