Many people will see the brand JB when buying watches, so what brand is JB? In fact, JB is Blancpain watch, and the two English letters JB are also the abbreviation of the name of the founder of Blancpain watch. Blancpain always insists on producing manual mechanical watches during the production process. Blancpain's production process is quite troublesome. Every watch leaving the factory needs to be inspected by a watchmaker, and each watch needs to be engraved with a number. Signing watches is a tradition that has continued since the birth of Blancpain watches to this day. Blancpain is a Swiss watch brand with a relatively long history. It designs and develops all its watches independently.
