Strap for Super Chronomat B19 44 Perpetual Calendar 140th Anniversary

The Breitling Super Chronomat RB19301A1G1S1 features a lug width of 22mm. This measurement is crucial when selecting an aftermarket strap: any 22mm straight-end strap will be compatible, provided you also verify the lug curvature for a proper fit against the ceramic and red gold case.

For the Super Chronomat RB19301A1G1S1, vegetable-tanned alligator leather is the premier choice for formal settings, as its warm tones complement the red gold elements. A high-density vulcanised rubber strap is ideal for sport use, honouring the model's aeronautical heritage. A ballistic nylon NATO strap offers a versatile everyday option that visually balances the 44mm case diameter.

The Super Chronomat secures its integrated bracelet via standard spring bars. Using a spring bar tool or a fine-bladed screwdriver, compress the spring bar and slide the bracelet free from the lug. Take care not to scratch the ceramic case: rest the watch on a soft cloth and work under good lighting. Replacing the bracelet with a 22mm strap is fully reversible at any time.

Yes, the aftermarket offers an extensive range of options for the 22mm lug width of the Super Chronomat. Milano Straps crafts bespoke straps in alligator, calf leather, shell cordovan, and rubber, all available in the correct width. It is essential to select a straight-end strap and to verify that the lining thickness is compatible with the deployant clasp or butterfly buckle you intend to use.

The lifespan of a leather strap depends on the quality of the tanning process, daily usage, and maintenance. A high-grade alligator strap, conditioned with appropriate creams and stored correctly, can accompany the Super Chronomat for three to five years with regular wear. Shell cordovan, owing to its dense fibre structure, tends to develop a distinctive patina over time and resists moisture better than calf leather. Milano Straps provides an 18-month guarantee against manufacturing defects on all its straps.
