Unless something gone wrong terribly, the Richemont group (IWC, Vacheron, Lange, Panerai, Baume, MB, Cartier etc), Swatch group (Omega, Breguet, Longines etc), LVMH (Tag, Zenith, Hublot, etc), Rolex, Citizen, and Seiko, are all quite formidable. Its unlikely (I didn't conclude that they won't) that any of these brands will be wound up technically/ legally given their stronghold (their parent co) backings. If any, maybe some of these brands will be phased out by their board in the future.
