FAQ

What is the lug width of the Breguet Classique 5719PT/EU/9ZV/DD0D?

The Breguet Classique 5719PT/EU/9ZV/DD0D is fitted with an 18mm lug width. This is the measurement to use when selecting any replacement or aftermarket strap compatible with this reference.

What is the best strap for the Breguet Classique 5719PT/EU/9ZV/DD0D?

For a 46mm platinum case with guilloché dial, the most suitable strap is Mississippi alligator or hornback crocodile in midnight blue or slate tones. Black or burgundy box-calf leather is the most versatile alternative for daily wear, thanks to its compactness and the patina it develops over time.

How do you change the strap on the Breguet Classique 5719PT/EU/9ZV/DD0D?

The strap is replaced using a dedicated 18mm spring bar and a flat or curved-tip strap tool. The platinum lugs on the 5719PT are substantial: it is recommended to work on a soft cushion to avoid scratching the case and to have the operation performed by a watchmaker or specialized atelier such as Casati Milano.

Are there aftermarket straps compatible with the Breguet Classique 5719PT/EU/9ZV/DD0D?

Yes. Any 18mm aftermarket strap is technically compatible with the Breguet Classique 5719PT/EU/9ZV/DD0D, provided that the spring bars have the correct length for the platinum lugs. A selection of 18mm straps in various materials and finishes is available on milanostraps.it, with the possibility of custom creation through the Casati Milano atelier.

How long does a leather strap last on the Breguet Classique 5719PT/EU/9ZV/DD0D?

A quality leather strap — alligator or box-calf — paired with a 46mm platinum case has an average lifespan of 18-36 months with regular use, varying based on perspiration, humidity exposure, and maintenance. Casati Milano straps are covered by an 18-month warranty against manufacturing defects and benefit from hand-selected leathers that guarantee greater durability over time.
