Strap for Nature Watch

The lug width of the H. Moser & Cie Heritage 8327-1200 is 20mm. This measurement represents the distance between the two lugs of the case where straps attach. To verify compatibility with a new strap, measure the distance from the inside of one lug to the inside of the other, perpendicular to the case axis.

For the 8327-1200, straps in dark brown or cognac alligator offer the ideal balance between sobriety and aesthetic definition. Calf leather with vegetable tanning is equally appropriate, developing a natural patina that harmonises with the steel's ageing process. For more dynamic usage, a slate grey NATO maintains the model's formal coherence.

To change the strap on the 8327-1200, remove the spring bars that connect the integrated bracelet to the case lugs. Use a precision tool (spring bar tool) to extract the bars, ensuring you retain the internal springs. After extraction, the new 20mm strap can be installed in the lugs. We recommend having a professional perform this operation if you lack experience.

Yes, all straps with a 20mm lug width are compatible with the 8327-1200. Milano Straps offers a dedicated collection of artisanal straps in premium leather, NATO, and rubber, selected to ensure both aesthetics and functionality. Each strap is available for rapid shipment and can be personalised according to customer preferences.

The lifespan of a leather strap depends on the material and usage patterns. A quality vegetable-tanned calf strap, used daily, has an average lifespan of 3-5 years. Alligator, being more resistant to tension, can last 5-7 years. The patina that develops over time makes the strap increasingly attractive aesthetically, but once structural deterioration becomes evident, replacement is advisable.
