What is the lug width of the Breitling Super Chronomat UB0136251L1S1?

The Breitling Super Chronomat UB0136251L1S1 takes a strap with a lug width of 20mm. This measurement refers to the internal distance between the case lugs where the strap is secured by the spring bar. It is advisable to verify the measurement with a calliper before ordering an aftermarket strap.

What is the best strap for the Breitling Super Chronomat UB0136251L1S1?

For the Super Chronomat UB0136251L1S1, with its ceramic, red gold and stainless steel case, the most suitable options are vegetable-tanned alligator leather to enhance the luxury element, box-calf leather for refined daily wear, shell cordovan for a noble patina, and vulcanised rubber to preserve the watch's sporting character. The choice depends on the intended context and desired colour pairing.

How do you change the strap on a Breitling Super Chronomat UB0136251L1S1?

To replace the strap on the Super Chronomat UB0136251L1S1, a fine-tipped spring bar tool is required. Insert the tip into the lateral slot of the spring bar, compress it and slide the original strap free. Pay close attention to the end curvature of the new strap: the Super Chronomat's lugs call for a straight or slightly shaped end for a precise fit. If in doubt, the operation can be carried out by a watchmaker or at the Casati Milano atelier.
