Strap for Superocean 46 Blacksteel / China

The lug width of the Breitling Superocean M173671A1B1S1 is 24mm. This measurement is specific to this model and is the correct size for ordering a compatible strap. Always measure the space between your watch's lugs before purchasing to ensure precise compatibility.

For the Superocean M173671A1B1S1, we recommend alligator or vegetable-tanned leather for everyday wear, which emphasise the case's elegance. For water activities, choose FKM rubber or NATO fabric straps, materials resistant to salt water and quick-drying. Your choice depends on the watch's primary use.

Remove the watch from your wrist and place it on a soft surface. Use a spring bar tool to gently press the strap spring towards the centre, releasing the old strap. Insert the new strap into the lugs and allow the spring to snap into place. Ensure both springs are fully secured before wearing the watch.

Yes, you can use an aftermarket strap compatible with a 24mm lug width. Always verify that the width matches exactly and that the strap is of certified quality to avoid damage to the delicate case lugs. Custom artisan straps offer the best quality control and personalisation options.

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years with ordinary care before showing visible wear. Frequent exposure to perspiration, fresh water, and sunlight accelerates ageing. An FKM rubber strap lasts longer (5–7 years), whilst NATO fabric can resist up to 8–10 years with regular maintenance.
