What is a spiral Breguet?

A spiral Breguet refers to a pocket watch produced with a component called the Breguet balance spring. It gets its name from the coiled design of the part. Keep in mind that "spiral Breguet" is a nickname. The company never engraved these words on any of their timepieces. If you see the phrase on the back of a watch, it is likely counterfeit.
