FAQ

What is the lug width of the Breitling Galactic A1336410/A569/731P?

The Breitling Galactic A1336410/A569/731P has a lug width of 20mm. This measurement refers to the internal distance between the two lugs of the case, measured perpendicularly to the longitudinal axis of the watch using a calliper. Any strap with a 20mm attachment is compatible with this reference.

What is the best strap for the Breitling Galactic A1336410/A569/731P?

For the Breitling Galactic A1336410/A569/731P, alligator Louisiana or Hornback straps with a steel deployant clasp are the most coherent choice given the watch's positioning. Shell cordovan is recommended for those seeking a natural patina over time. For a more sportive register, a vulcanised rubber strap or a nylon NATO strap complement the brand's aeronautical DNA effectively.

How do you change the strap on a Breitling Galactic A1336410/A569/731P?

The Breitling Galactic A1336410/A569/731P uses a standard lug system allowing strap replacement with a springbar tool. By inserting the tool into the lateral hole of the lug, the spring bar is compressed and the strap is released. Care should be taken not to scratch the polished surfaces of the case. If in doubt, consult a watchmaker or the Casati Milano atelier.

Milano Straps offers a selection of handcrafted straps in various leathers and materials, available bespoke or ready to purchase online, all with a certified 20mm fitting.

How long does a leather strap last on a Breitling Galactic A1336410/A569/731P?

The lifespan of a leather strap depends on the quality of the tanning, the thickness of the hide and the conditions of use.
