FAQ

What is the lug width of the Breitling Super Chronomat U19320161C1S1?

The Breitling Super Chronomat U19320161C1S1 has a lug width of 20mm. This measurement is taken between the two upper lugs using a digital calliper. Aftermarket straps must match this width precisely to ensure a correct fit and proportionate appearance on the 44mm case.

What is the best strap for the Breitling Super Chronomat U19320161C1S1?

For the Super Chronomat U19320161C1S1, the most suitable materials are smooth alligator — which complements the ceramic bezel texture — and vegetable-tanned calf leather for those seeking an authentic patina over time. Shell cordovan offers a compact, almost metallic surface that pairs well with the 18-carat red gold details. A 20/18mm taper is recommended to maintain correct proportions on the wrist.

How do you change the strap on the Breitling Super Chronomat U19320161C1S1?

The original integrated Rouleaux bracelet is removed using the quick-release push-buttons on the lugs. To fit an aftermarket strap, the original spring bars must be removed with a dedicated springbar tool and replaced with compatible 20mm spring bars. It is advisable to have this done by a watchmaker or specialist atelier to avoid scratching the ceramic case.

Are there aftermarket straps compatible with the Breitling Super Chronomat U19320161C1S1?

Yes. Any strap with a standard 20mm spring bar attachment is technically compatible with the Super Chronomat U19320161C1S1, provided the overall length and taper are appropriate for the 44mm case. Milanostraps.it offers a handcrafted selection of 20mm straps in leather, rubber, and technical materials, produced by Casati Milano to Haute Couture standards.

How long does a leather strap last on the Breitling Super Chronomat U19320161C1S1?

The lifespan of a leather strap depends on the material and usage. A quality alligator strap with proper tanning typically lasts 3 to 5 years with regular wear. Shell cordovan and vegetable-tanned calf leather can exceed 5 years, developing a distinguished patina. Key factors are exposure to perspiration, water, and heat. For intense physical activity, a vulcanised rubber strap is recommended instead.
