Frequently asked questions

What is the lug width of the Breitling Premier AB0118A11L1X1?

The lug width of the Breitling Premier AB0118A11L1X1 is 22mm. This measurement is standard across the entire Premier 42mm family and allows aftermarket straps with a 22mm attachment to be fitted without adapters. For an accurate measurement, use a digital calliper to measure the internal distance between the two lugs on the caseback side.

What is the best strap for the Breitling Premier AB0118A11L1X1?

For the Breitling Premier AB0118A11L1X1, an alligator strap with hornback grain is the most consistent choice with the Premier family's luxury positioning. Alternatively, a Tuscan vegetable-tanned calf leather strap develops a natural patina that improves with daily wear. For less formal settings, box calf leather or a quality nylon NATO strap preserves the dial's character without adding visual weight to the wrist.

How do you change the strap on a Breitling Premier AB0118A11L1X1?

The strap on the Breitling Premier AB0118A11L1X1 is removed using a flat-tip springbar tool: insert the tool into the lateral notch of the lug, compress the spring bar, and slide the strap outward. No specialist equipment is required, though it is advisable to protect the case with a soft cloth to avoid scratching the satin-finished surfaces.

Are there aftermarket straps compatible with the Breitling Premier AB0118A11L1X1?

Yes, any strap with a 22mm attachment is compatible with the Breitling Premier AB0118A11L1X1, provided the spring bars have a standard diameter of 1.5mm and a length of 22mm. Milanostraps.it offers a selection of handcrafted 22mm straps made to order, with the option to customise leather type, stitching, buckle and taper.

How long does a leather strap last on the Breitling Premier AB0118A11L1X1?

The lifespan of a leather strap on the Breitling Premier AB0118A11L1X1 depends on the tanning method and frequency of use. A quality alligator strap, maintained regularly with a nourishing cream, can last between 3 and 5 years with alternating daily wear. Vegetable-tanned calf leather, thanks to its dense fibrous structure, achieves comparable longevity whilst developing a distinctive patina. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
