Strap for Super AVI B04 Chronograph GMT 46 Mosquito

The lug width of the Breitling AVI YB04451A1B1X1 is 24mm. This measurement defines the distance between the vertical lugs on the case and is critical for strap compatibility. Verify it using a calliper placed perpendicular to the connecting tube, measuring from the inside of one lug to the inside of the other.

For a 46mm aviation chronograph, we recommend natural alligator or shell cordovan in vegetable tanning: the pronounced grain accepts patina beautifully and creates visual harmony with the ceramic case. A tactical nylon NATO strap offers a practical alternative for dynamic environments whilst preserving the aeronautical heritage.

The Breitling AVI features standard spring bar attachments. Position your watch on a soft pad, insert the spring bar tool into the lateral grooves of the bar, apply gentle pressure to extract it. Repeat on the opposite side, then insert the new strap's spring bars into the same lugs, ensuring full engagement.

All 24mm straps are compatible with this model. On milanostraps.it you'll find handcrafted straps customisable in leather type, length, initials and stitching thread. Each strap is tested to guarantee perfect fit with Breitling lugs.

With regular use and conscious maintenance—avoiding prolonged moisture exposure and applying balm every 6-8 months—an alligator or cordovan strap will last 5-8 years. Vegetable-tanned leather ages naturally and patina development enhances aesthetic appeal. Milano Straps provides an 18-month guarantee on construction and stitching.
