VACU-PROOF is a sealing liquid for the re-sealing of sealed surfaces and gaskets or other sealants in waterresistant watches or other precision devices after their opening for services. VACU-PROOF is suitable for all waterresistant joints (e.g. watch-case, crown-shaft, glass). VACU-PROOF is also suitable for location the leaks in wrist watches in conjunction with a watch service unit for checking the watertightness (Leak Controller 2000).
