FAQ

What is the lug width of the Breitling Super Chronomat UB01361A1L1S1?

The lug width of the Breitling Super Chronomat UB01361A1L1S1 is 20mm. This measurement should be taken between the two lugs of the case using a millimetre calliper, positioning the tool at the innermost point of the lug rather than at the outer edge. Any aftermarket strap must explicitly list 20mm as its specification to ensure a proper fit.

What is the best strap for the Breitling Super Chronomat UB01361A1L1S1?

For the Super Chronomat UB01361A1L1S1 — featuring a case in ceramic, red gold and stainless steel — the most suitable materials are alligator leather in cognac or tobacco tones, which harmonises with the red gold, and vegetable-tanned calf leather for robust daily use. Shell cordovan in bordeaux or dark cherry is an option for connoisseurs. For sporting use, vulcanised rubber with a milled texture is the most functional choice. A deployant clasp in brushed steel or rose gold PVD is preferable to a standard buckle for even tension distribution.

How do you change the strap on the Breitling Super Chronomat UB01361A1L1S1?

The Super Chronomat features an integrated Rouleaux bracelet with proprietary lugs. To replace it with an aftermarket strap, the original bracelet must first be removed using Breitling's dedicated tools or by a qualified watchmaker. Once removed, standard spring bars are fitted and any 20mm strap can be installed using a spring bar tool. It is strongly advised to retain the original bracelet to preserve the watch's value.

Are there aftermarket straps compatible with the Breitling Super Chronomat UB01361A1L1S1?

Yes. Once the integrated bracelet of the Super Chronomat UB01361A1L1S1 has been removed, the watch accepts any standard 20mm strap with conventional spring bars. Milano Straps offers a selection of handcrafted 20mm straps in alligator, calf leather, shell cordovan and rubber, produced by the Casati Milano atelier, all compatible with this Breitling reference. Material, colour and clasp can be fully customised.

How long does a leather strap last on a Breitling Super Chronomat?

The lifespan of a leather strap depends on the material, frequency of use and exposure to perspiration and water. A quality vegetable-tanned calf strap, worn on rotation, typically lasts 18 to 36 months. Alligator leather, owing to its naturally oily scale structure, tends to last longer when properly maintained. Shell cordovan, due to its dense fibrous composition, is the most durable of the traditional leathers. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
