Strap for Belluna Royal Lady Rose Gold / MOP

The lug width is 16.00mm, measured from centre to centre of the spring bar pins. This unconventional measurement is specific to the case geometry and ensures balanced proportions between diameter and lug depth.

The ideal strap is vegetable-tanned calf leather, which enhances the formal elegance of the case and develops a rich patina over time. Alligator represents the luxury option. For versatility, a cotton-nylon NATO strap is a practical and durable solution.

Use a spring bar tool to gently lift the spring bar whilst extracting the strap. Position the spring ring in its seat on the pin, then insert the new strap, ensuring the spring is fully seated in its groove. The 16mm strap inserts under pressure without forcing.

Yes, it is advisable to select straps specific to 16mm lug width. Artisanal straps of superior quality, made with traceable materials and bespoke construction, guarantee impeccable fit and superior build longevity compared to generic products.

A quality leather strap, subject to regular maintenance and annual conditioning with natural wax, lasts between 4 and 7 years of daily wear. Lifespan depends on solar exposure, humidity, frequency of wear and tanning quality. Vegetable tanning, though more delicate, develops an aesthetic patina appreciated by connoisseurs.
