Strap for Chronospace Automatic

The lug width is 24mm. This dimension is specific to professional Breitling models in large format and allows balanced strap distribution across the robust Chronospace case. Measure the distance between the inner edges of the spring bars to verify exact compatibility.

The choice depends on your use case. For formal settings, a black alligator strap with brushed steel deployant clasp offers discreet elegance. For tactical and dynamic use, a NATO in regenerated fibre maintains avionic heritage. A calf leather with textured grain in cognac tones represents the compromise between formality and practicality. In aquatic or intense work environments, technical rubber with texture is the most reliable solution.

The Chronospace uses standard spring bars. Obtain a dedicated spring bar removal tool or consult a watchmaker. Gently press the bar inward toward the case to release the internal spring, then remove the old strap. Insert the new strap by aligning the holes with the bar ends and allow the spring to retain them in position.

Yes, any 24mm strap is compatible. Milano Straps offers artisanal straps in alligatore, calf, NATO, and rubber, all customisable in sizing, initials, and thread colour. For optimal bespoke results with leather choice and construction details, the Casati Milano atelier creates dedicated straps with an 18-month warranty.

A quality leather strap (alligatore or calf with vegetable tanning) lasts 3–7 years in daily wear, depending on climate, frequency of use, and maintenance. Vegetable-tanned leather develops natural patina that aesthetically extends its lifespan. Technical rubber lasts 4–6 years before showing wear. NATO in regenerated fibre is virtually indestructible, though thread may fray after 8–10 years of intensive use.
