Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Black / Blue / Milanese

The lug width of this model is 24mm. This measurement is taken between the spring bars that attach the strap to the case and represents the standard for high-end diving watches and chronographs. A 24mm lug-width strap ensures secure and proportionate mounting on this reference.

For the Superocean Heritage, we recommend alligator in brown tones for formal elegance, vegetable-tanned calf for daily versatility, or shell cordovan for authentic maritime use. If you prefer practicality, a NATO strap in waxed canvas or technical rubber maintains the original diver character. Your choice depends on the intended use context.

Strap replacement requires a spring bar remover tool to release the spring bars from the case lugs. Insert the remover into the small slot on one of the bars, push downward until the bar pops free, then remove the old strap. Mount the new strap by aligning the holes with the lugs and reinserting the bars until they click into place. If unsure, consult a qualified watchmaker.

Yes, any strap with a 24mm lug width is compatible with this model. Our artisanal leather or technical rubber straps mount directly onto your Breitling's original spring bars without requiring modifications. We recommend choosing thicknesses and construction proportionate to the 46mm case diameter.

Durability depends on the material and usage intensity. Quality alligator or shell cordovan can last 5–7 years with regular maintenance and moderate use. Vegetable-tanned calf offers similar longevity, whilst a strap in intensive use or exposed to excessive moisture may require replacement within 2–3 years. Keeping it dry and clean significantly extends its lifespan.
