Strap for Khaki Navy Scuba Quartz 37 Stainless Steel / Black / NATO

The lug width of the Hamilton Khaki Navy H82201931 is 18 millimetres. This is measured from inside to inside of the case lugs. This less common measurement on modern sports watches represents a deliberate constructive choice by Hamilton to maintain harmonious proportions on the 37mm case.

It depends on usage and context. A tobacco alligator strap or vegetable-tanned calf in grey-charcoal elevates the military aesthetic toward formal registers. For dynamic use, a cotton-woven NATO or FKM rubber offers comfort and robustness. Burgundy shell cordovan creates sophisticated contrast with the navy dial.

The change is performed by removing the attachment pins with a dedicated tool: a spring bar tool or small screwdriver. Insert the tool into the pin end, applying gentle pressure until it slides completely through. Position the new strap, aligning the holes with the lugs, and slide the pin in the opposite direction until fully secured.

Yes. Any strap in the standard 18mm lug width is compatible with the model. MilanoStraps offers a specialised collection of 18mm straps in leather, NATO, and rubber, with finishes that complement the Khaki Navy's aesthetic palette. Shipping is rapid and products are customisable in specific finishes.

A vegetable-tanned leather strap of artisanal quality lasts on average 3-5 years with daily wear, with variability due to climate, frequency of wear and maintenance. Prolonged sun exposure and humidity accelerate wear; periodic cleaning with damp cloth and annual conditioning with natural oils significantly extend lifespan. The patina that develops over time aesthetically enriches the material.
