Frequently asked questions

What is the lug width of the Breitling Chronoliner Y2431016.C970.101X?

The Breitling Chronoliner Y2431016.C970.101X has a lug width of 22mm. This is the internal distance between the lugs measured at the case base and is compatible with any standard 22mm strap, optionally tapering to 20mm at the buckle end.

What is the best strap for the Breitling Chronoliner Y2431016.C970.101X?

Given the 46mm ceramic and steel case of the Chronoliner, the most suitable materials are vegetable-tanned alligator in matte black or anthracite, navy blue box-calf leather, and black vulcanised rubber for sport use. A brushed or PVD black deployant clasp improves wrist comfort compared to a standard pin buckle.

How do I change the strap on the Breitling Chronoliner Y2431016.C970.101X?

You will need a fine-tipped springbar tool. Insert the tip into the springbar slot on the inner side of the lug, compress the springbar and slide the strap free. Repeat on the opposite lug. To fit the new strap, hook one end of the springbar, compress and seat the other end. Work on a soft surface to protect the ceramic bezel and case from scratching.

Are there aftermarket straps compatible with the Breitling Chronoliner Y2431016.C970.101X?

Yes. Any strap with a 22mm lug width is compatible with the Breitling Chronoliner Y2431016.C970.101X. MilanoStraps offers a curated range of handcrafted leather, rubber and nylon straps sized specifically for this reference, with customisable taper, buckle and deployant options.

How long does a leather strap last on a Breitling Chronoliner Y2431016.C970.101X?

Longevity depends on the material and conditions of use. A quality vegetable-tanned alligator strap, properly maintained with leather conditioner every two to three months and rotated with other straps, can last between three and seven years. Smooth calf leather is more susceptible to perspiration. Vulcanised rubber is the most resistant to moisture and sweat and is ideal for continuous daily wear.
