Why Choose This O‑Ring Gasket?
When a watch’s case back or crown isn’t sealed properly, moisture can infiltrate the movement, leading to rust, loss of accuracy, or complete failure. Our O‑ring and silicone grease combination restores the original factory seal, extending the life of your watch while maintaining its aesthetic integrity.
How It Works
The soft silicone O‑ring conforms to the irregularities of the case back or crown stem, while the specially formulated grease fills microscopic gaps, creating a barrier that repels water and contaminants. This dual‑action system ensures a consistent, leak‑free environment for the movement.
Perfect For
