Frequently asked questions

What is the lug width of the Breitling Galactic WB3510U0.A777.433X?

The lug width of the Breitling Galactic WB3510U0.A777.433X is 22mm. This measurement is taken with a digital calliper positioned internally between the two lugs, at the strap attachment point. It is the key technical specification required when selecting a compatible aftermarket strap.

What is the best strap for the Breitling Galactic WB3510U0.A777.433X?

The ideal strap for the Breitling Galactic WB3510U0.A777.433X depends on the context of use. A semi-gloss alligator strap in tobacco brown or deep navy complements the tungsten and stainless steel case in a dressy-sport pairing. Vegetable-tanned Tuscan calfskin is well suited to daily wear, while vulcanised rubber is preferred for sporting use. The lug width is 22mm in all cases.

How do you change the strap on the Breitling Galactic WB3510U0.A777.433X?

To replace the strap on the Breitling Galactic WB3510U0.A777.433X, a fine-tipped spring bar tool is required. Insert the tip into the slot on the lug, compress the spring bar and slide the strap free. Exercise care to avoid scratching the tungsten lugs. It is advisable to work on a soft surface and to use 1.8mm diameter replacement spring bars.
