Strap for Superocean Heritage 46 Stainless Steel / Black / Stratus Silver / Milanese

The lug width of the Breitling Superocean Heritage A1732024.G642.152A is 24mm, measured as the distance between the horizontal lugs (spring bar holes) on the watch case. This dimension is critical for aftermarket strap compatibility. It is advisable to verify the measurement with a digital calliper to ensure precise conformity. All straps sold by Milano Straps for this size are certified prior to dispatch.

Three primary orientations are recommended for this reference. An alligator strap in natural or tinted finishes offers formal elegance and visual contrast with the steel case; a vegetable-tanned calf leather in tobacco brown or deep black introduces patina development and character over time; a NATO strap in technical textile ensures practicality and moisture resistance for daily wear. Selection depends on intended usage context and personal aesthetic preference.

Strap replacement requires removal of the two horizontal spring bars that connect the lugs to the case. Utilise a dedicated strap-changing tool or a fine flathead screwdriver to apply pressure on the internal spring mechanism until the pin protrudes. Repeat on the opposite lug, then insert the spring bars into the new strap by aligning the holes. The procedure is reversible and requires no specialist technical knowledge. Casati Milano offers strap-change service by appointment.

Yes, all straps with 24mm lug width are compatible with the Superocean Heritage A1732024.G642.152A. Milano Straps manufactures bespoke artisanal straps in this dimension, customisable in leather type (alligator, calf, shell cordovan), colour, stitching thread, and length. Compatibility is guaranteed by lug-width uniformity; however, verification with a calliper prior to purchase is advisable.

Leather strap durability depends on frequency of use, environmental exposure, and tanning methodology. Vegetable-tanned calf leather, under moderate moisture and wear conditions, maintains structural integrity for 3–5 years. Alligator leather, owing to superior fibre density, may extend to 7–8 years. Prolonged exposure to direct sunlight, chlorine, and saltwater accelerates ageing. Periodic maintenance with neutral pH soap and protective treatments extends functional lifespan. Casati Milano provides an 18-month warranty on bespoke handcrafted straps.
