then again who really knows. The history of Swiss watchmaking is littered with glorious brands that have faced failure/decline after decades of success: Breguet, Blancpain, Angelus, Minerva to name a few I know about. Even the great maisons like Patek, AP, and Vacheron had periods of struggle in the past century. Every maison will face a challenge in the long term with the business cycle of boom times & bust times.
