Strap for Navitimer Big Case 1806

The lug width of the Breitling Vintage Ref. 1806 is 24mm. This measurement defines the attachment span between the case lugs where the strap connects. To verify this measurement on your watch, use a digital calliper and measure the distance between the two lugs without including the pins themselves. This specification is essential for ordering a compatible aftermarket strap.

For the Breitling Vintage 1806, we recommend three material categories: genuine alligator (natural grain, dark brown or cognac tones) for aesthetic refinement; vegetable-tanned calf leather (develops character patina over time, harmonious aging); vulcanised natural rubber (maximum water resistance, 5–8 year durability). The choice depends on intended use: alligator for formal wear, calf for versatile daily use, rubber for professional aviation context.

Changing the strap on the 1806 requires a pin remover tool or a very fine screwdriver. Position the watch on a stable surface, locate the horizontal pins securing the strap to the case (typically one on each side), and gently push from inside toward the outside with the tool to slide them out. Remove the old strap and insert the new one by aligning the holes and pushing the pin until it clicks into position. Avoid striking with a hammer, as this will damage the case.

Yes, any strap of the correct 24mm lug width is compatible with the 1806. Before purchasing, verify that the strap is specified for 24mm and that the thickness does not exceed 3.5mm (to avoid restricting case rotation). Milano Straps artisanal straps are manufactured to these specifications and undergo quality control before dispatch.

The lifespan of a natural leather strap varies depending on material, usage, and maintenance. Vegetable-tanned calf leather: 4–6 years of daily wear. Alligator, if maintained with specific balms: 5–7 years. Vulcanised rubber: 6–8 years. To extend life, avoid wearing the watch during showers or baths (even with water-resistant straps), apply a specific leather balm every 6 months, and ensure the strap dries completely after accidental moisture exposure. Casati Milano warranty: 18 months on all artisanal straps.
