Strap for Superocean Heritage B31 Automatic 44 Stainless Steel / Green / Rubber

The lug width of the Breitling Superocean Heritage AB3112361L1S1 is 22mm. This measurement is taken between the two lugs using a millimetre calliper, and is the standard reference for all compatible replacement straps.

For the Superocean Heritage AB3112361L1S1 with its steel and ceramic case, the most suitable options are a matte alligator strap for formal wear, a vegetable-tanned Tuscan calf leather strap for daily use with natural patina development, and a nylon NATO strap to honour the original tool-watch spirit. The choice depends on context and dial colour: the blue sunburst pairs particularly well with Havana brown or midnight blue.

Use a spring bar tool to remove the strap: insert the tip into the slot between the lug and the spring bar, compress the spring and slide the bar out of the lug hole. Take care not to scratch the ceramic bezel. Work on a soft surface and, if in doubt, consult a watchmaker or the Casati Milano atelier.

Yes, any strap with a 22mm lug width and standard spring bars is compatible with the Superocean Heritage AB3112361L1S1. Milano Straps offers a curated selection of handcrafted 22mm straps in leather, alligator, calf, and technical materials, available with buckles or deployant clasps in various finishes.

Longevity depends on leather quality and usage. A vegetable-tanned strap, regularly conditioned and kept away from saltwater, can last between two and five years whilst developing a distinguished aged patina. For frequent diving or water exposure, vulcanised rubber or nylon NATO straps are recommended for their inherent moisture resistance.
