A small grease box of silicone gasket grease, an essential watchmaker tool to keep case gaskets supple and water-resistant.
Product overview
This gasket grease box is a key watchmaker tool used to lubricate every case gasket during a service: case-back O-ring, crown gasket, crystal seal or pusher seal. The neutral silicone grease keeps elastomers supple, prevents micro-cracking and restores water-resistance to the manufacturer specification on Seiko divers, Omega Seamaster, Rolex-compatible references and most modern quartz watches. Owning the proper instruments is the first step toward enjoyable, repeatable watch servicing on the bench at home or in a professional workshop. This watchmaker tool belongs to a broader range of horological accessories trusted by amateur restorers, vintage watch collectors and professional repair benches alike. Every stage of a watch service from case-back removal, gasket inspection, movement cleaning, bracelet sizing to crystal pressing benefits from dedicated, correctly sized instruments. Investing in the right tool prevents costly scratches on polished bezels, broken lugs, sheared screw heads or damaged spring bars. Whether you service a Seiko 5, an Omega Speedmaster, a Rolex Submariner clone or a Bergeon-compatible reference, working with proper hand tools dramatically reduces the risk of damaging your timepiece. Many enthusiasts start with battery changes on quartz watches and gradually move to bracelet adjustments, then case-back openings, before attempting movement work. Each phase needs its own specialised instruments, and assembling a full kit over time is more economical than buying a closed boxed set. Always work on a clean, well-lit bench, ideally on a soft mat that catches small parts, and keep a magnetic tray nearby for screws and pins. Lubricants like Moebius oils, drying papers and a dedicated dust blower complete the typical workshop. Combine this item with a watch holder, a 10x loupe and a fine screwdriver set ranging from 0.6 mm to 2.0 mm for a fully functional repair station. The hardness of working surfaces is calibrated around 55 to 60 HRC on most professional benches, ensuring repeatable results without marking the workpiece. Used carefully and stored away from humidity, this watchmaker tool will support hundreds of services without significant wear, and will pay for itself after only a few interventions on quartz or mechanical calibres. The bench is the heart of any watch service: a stable holder, focused light, soft work mat and tidy parts tray make every operation safer and faster. Adding this watchmaker tool to that environment turns a casual workspace into a small atelier capable of professional results on quartz and mechanical calibres alike.

How to use
- Remove the case-back and extract the gasket gently
- Inspect the gasket for cracks and deformation
- Pick up a small dab of grease with a wood toothpick
- Spread an even thin film around the gasket

Quality & origin
Manufactured to a watchmaker grade with neutral silicone base. Each box is sealed before shipping; stored away from direct sunlight, the grease keeps its properties for years.
FAQ
Will it dissolve old gaskets?
No, the grease is fully compatible with NBR and FKM elastomers used on Seiko, Omega and Rolex-style gaskets.
How much grease per service?
A pinhead-sized dab is enough for a complete case-back gasket service.
Does it restore water-resistance?
The grease itself does not seal; combined with a sound gasket it restores the original water-resistance.
