Frequently asked questions

What is the lug width of the Breguet Marine 9509BB/5R/984/RD0R?

The lug width of the Breguet Marine 9509BB/5R/984/RD0R is 20mm. This is the internal distance between the two lugs on the case and must be measured precisely to ensure proper fitment of a replacement strap or bracelet.

What is the best strap for the Breguet Marine 9509BB/5R/984/RD0R?

For this 33.80mm white gold Marine, a smooth alligator strap with a polished finish in midnight blue or slate gray represents the most coherent choice with the watch's aesthetics. Alternatively, a box-grain calf leather or vulcanized rubber strap are valid options for daily or sports use.

How do you change the strap on the Breguet Marine 9509BB/5R/984/RD0R?

The integrated bracelet on the Marine 9509 is removed using special spring bars inserted into the case lugs. It is advisable to entrust this task to a watchmaker or specialized atelier to avoid scratching the white gold case. Once the bracelet is removed, a 20mm aftermarket strap can be fitted like on any standard watch.

How long does a leather strap last on a Breguet Marine 9509BB/5R/984/RD0R?
