🔧 What it does & how to use

This silicone grease is applied to watch case gaskets and o-rings before fitting, helping them seal properly and last longer without perishing or drying out. It's suited to hobbyist and professional watch repairers working on case backs, crowns and glass seals.

• Clean first: wipe the gasket or o-ring and its seating surface free of old grease, dust and debris.
• Apply sparingly: use a small amount of grease on your fingertip or a fine brush to coat the gasket evenly.
• Fit the gasket: seat it correctly into its groove or channel, checking it isn't twisted or pinched.
• Reassemble: close the case back, crown or glass as normal, ensuring the gasket stays seated.

We also stock a range of round and flat watch gaskets separately, along with other watch, clock and jewellery tools and parts — please see our shop for the full range.
