Frequently asked questions

What is the lug width of the Breitling Avenger A1733010.B906?

The lug width of the Breitling Avenger A1733010.B906 is 20mm. This measurement is taken using a digital calliper positioned between the lower lugs of the case, measuring the internal gap between the two horns. Any straight-ended 20mm strap is compatible with this reference.

What is the best strap for the Breitling Avenger A1733010.B906?

Given its aeronautical vocation and substantial 45.4mm diameter, the Breitling Avenger A1733010.B906 pairs particularly well with vegetable-tanned alligator straps in a tapered 20/18mm profile, military-grained calfskin straps, or vulcanised rubber straps for sporting use. The optimal choice depends on the intended context: formal, casual, or technical.

How do I change the strap on the Breitling Avenger A1733010.B906?

The strap on the Breitling Avenger A1733010.B906 is removed using a flat-tip spring bar tool or a lever-type tool, inserted into the slot located between the lugs. The 20mm spring bars are compressed laterally and withdrawn. It is advisable to protect the case with a soft cloth during the operation. No specialist tools are required, though a steady hand and precision are essential.

How long does a leather strap last on the Breitling Avenger A1733010.B906?

The lifespan of a leather strap on the Breitling Avenger A1733010.B906 depends on the quality of the tanning process and frequency of wear.
