Frequently Asked Questions
Q: What does watch gasket grease do, and why is it important?
A: Watch gasket grease lubricates and conditions the rubber O-ring seals found in watch cases. These seals are critical for maintaining waterproofing — without proper lubrication, the rubber can dry out, crack, and lose its sealing ability over time. Applying gasket grease during servicing helps the O-ring seat correctly, creates a tighter seal, and extends the life of the gasket significantly.
Q: Which watch sizes is this O-ring gasket grease compatible with?
A: This repair tool is designed for a wide range of watch case sizes. The 0.5mm option covers diameters from 13mm to 37mm, the 0.6mm covers 13mm to 40mm, the 0.7mm covers 25mm to 40mm, and the 0.8mm covers 28mm to 38mm. This makes it suitable for everything from smaller dress watches to larger sport or dive-style cases.
Q: Can a beginner use this watch gasket grease at home?
A: Absolutely. This tool is designed to deliver professional results and is straightforward enough for hobbyists and first-time watch repair enthusiasts. Simply apply a thin, even coat of grease to the clean O-ring before reseating it. No special equipment is needed, making it ideal for DIY watch servicing at home.
Q: How often should I re-grease my watch gaskets?
A: Most watchmakers recommend re-greasing and inspecting O-ring gaskets every 1–2 years, or whenever a watch is opened for service. If a watch is regularly used around water, more frequent checks are advisable to ensure the waterproof seal remains intact.
