The Bergeon 4509 Silicone 7 Watch Gasket Grease is a premium Swiss-made waterproof silicone grease designed for lubricating and protecting watch case gaskets, case back seals, crown gaskets, O-rings, and threaded components during watch servicing. Trusted by professional watchmakers, horologists, and watch repair workshops, it helps maintain the water resistance of luxury, sports, diving, and everyday watches. Its high vacuum pressure waterproof formula prevents moisture from entering the watch case through worn or poorly fitting gaskets while keeping rubber seals soft, flexible, and properly lubricated. Bergeon Silicone 7 will not evaporate, will not affect watch oils, will not run, harden, or break down on threads, and remains stable under extreme pressure and temperature changes. The formula is completely resistant to moisture, salt water, sweat, acids, alkalis, and fungus, making it an essential consumable for maintaining reliable waterproof performance during professional watch repairs and servicing.
