Strap for Transocean Chronograph Unitime Stainless Steel / Black / Croco

The lug width of the Breitling Transocean AB0510U4.BE84.760P is 24mm. This measurement corresponds to the internal distance between the horizontal lugs of the case. A compatible strap must have a width between 23.8 and 24.2mm to ensure proper fit without play.

Nile alligator in vegetable tanning and aged Tuscan calf are the most appropriate materials. Alligator offers regular grain and compact surface that does not distract from the dial; calf develops natural patina over time, creating aesthetic dialogue with the ageing of the steel case. Both respect the formal grammar of a dress chronograph.

Removing the strap requires a spring bar tool to horizontally push the spring pin that secures the lug. Operate with care to avoid scratching the case. Insert the new strap by aligning the holes with the pins and push until you feel the safety click of the spring. We recommend having a professional watchmaker perform this operation the first time.

Yes, the Transocean accepts any 24mm strap of adequate build quality. Milano Straps offers artisanal straps in natural leather, vulcanised rubber, and nylon, all compatible with the 24mm lug width. Choice depends on aesthetic and usage preferences: leather for elegance, rubber for robustness, nylon for versatility.

A quality leather strap (alligator or Tuscan calf) lasts on average between 4 and 8 years with continuous use and routine maintenance. Durability depends on frequency of wear, sun exposure, humidity, and periodic cleaning. A vulcanised rubber or synthetic strap typically lasts between 8 and 12 years. Milano Straps provides straps with an 18-month warranty through the Casati Milano atelier.
