Strap for Heritage Navigator Săgeata Orientului / Flèche d’Orient

The lug width is 20mm, also referred to as ansa width. This measurement defines the space between the two lugs of the case through which the strap passes. The 20mm dimension was specifically chosen by the Swiss manufacturer to maintain optimal proportions relative to the 43mm case diameter, allowing for robust leather straps, NATO fabrics, or technical rubber without visual imbalance.

There is no universal answer, as it depends on usage and personal preference. Vegetable-tanned alligator offers maximum elegance and a patina that evolves with time, ideal for formal occasions. European calf leather represents an excellent balance between quality and cost. A NATO strap in cotton or cordura provides versatility and durability, perfect for those seeking fluid transitions between different contexts. For water exposure, FKM rubber is recommended.

Strap changes require a spring bar tool. Position the thin end of the tool into the slot of one elastic lug pin, press gently inward to release tension, and the pin will disengage. Repeat on the other side. Align the new strap's holes with the case lugs and re-insert the elastic pins by pressing until they click into place. Verify that the strap is securely fastened with no lateral movement.

Yes, provided it is 20mm in lug width. Third-party straps often offer greater colour and material variety compared to original equipment manufacturer offerings. It is essential to verify that the pin holes align correctly with the case lugs and that there is no lateral play once installed. Milano Straps provides a range of tested 20mm straps for compatibility assurance.

Lifespan depends on leather quality and intensity of use. Vegetable-tanned alligator, if properly cared for (protected from excessive humidity and heat), can last 5-7 years in daily wear. High-quality European calf typically offers 3-4 years of service. The buckle and elastic pins will wear before the strap itself. Rotating between multiple straps distributes wear and extends the life of each.
