Priory Turret Clock Oil is a high-viscosity mineral oil formulated for larger clocks, turret clocks and clock mechanisms where a heavier oil is required.
It is a long-lasting anti-wear lubricant designed to provide protection for large clock mechanisms operating over extended periods.
The oil combines a high viscosity index with excellent low-temperature performance, corrosion protection, oxidation resistance and thermal stability.
With a pour point of -38°C, it provides reliable lubrication in very cold conditions while maintaining its performance across a wide operating temperature range.
Priory Turret Clock Oil is sourced by Priory Polishes and was developed as an improved replacement for the previously supplied Windles oil.
Available in 50ml and 100ml sizes.
Turret Clock Oil is intended for larger clock mechanisms and applications where a higher-viscosity, heavier oil is required.
Typical applications include:
The higher viscosity makes this oil particularly suitable where the lighter Priory Clock Oil is not the appropriate choice.
Priory Turret Clock Oil has been formulated with a range of properties designed to provide long-lasting lubrication and protection:
Its high shear stability helps the oil maintain its viscosity during service, while its oxidation resistance helps reduce deterioration during long-term use.
Not every clock mechanism requires a high-viscosity oil. Smaller clock movements generally require a lighter clock oil, whereas larger mechanisms may require a heavier oil to provide appropriate lubrication.
Priory Turret Clock Oil is intended for larger mechanisms and turret clocks where this higher viscosity is appropriate.
For smaller and medium-sized clock movements, see our Priory Polishes Clock Oil, a medium-viscosity mineral oil specifically designed for clock movements.
Choosing the correct viscosity is important when servicing a clock. If you are unsure which oil is appropriate for a particular movement, check the manufacturer’s lubrication specification or consult an experienced clock repairer.
Apply the Oil sparingly to the appropriate lubrication points in the clock mechanism.
Only a small amount of oil is required. Excessive oil can spread to areas where lubrication is not required and may attract dust or contamination.
A suitable fine oiling tool can be used to place a controlled amount of oil precisely where required.
When servicing an older mechanism, clean away old contaminated oil and dirt before applying fresh lubricant where appropriate.
Always follow the lubrication requirements of the particular clock movement and avoid lubricating parts that are not intended to be oiled.
Priory Polishes supplies both Turret Clock Oil and a medium-viscosity Priory Clock Oil for different horological applications.
A high-viscosity mineral oil intended for larger clocks and mechanisms where a heavier oil is required.
A medium-viscosity, high-purity mineral oil designed for clock movements and watches.
In simple terms, Turret Clock Oil is the heavier option for larger mechanisms, while Priory Clock Oil is intended for smaller and medium-sized clock movements and watches.
Using the correct viscosity for the mechanism is important, so always check the manufacturer’s lubrication requirements where available.
It is a high-viscosity mineral oil designed for larger clocks and mechanisms where a heavier lubricant is required.
It is primarily used for turret clocks, large clock mechanisms and other larger mechanical clocks where a higher-viscosity oil is appropriate.
Yes, where the particular antique clock has a large mechanism that requires a heavier oil. The correct viscosity should always be determined from the movement’s lubrication requirements.
This Oil is intended for larger mechanisms. For smaller clocks, a medium-viscosity clock oil such as Priory Polishes Clock Oil may be more appropriate.
Turret Clock Oil is the higher-viscosity, heavier oil intended for larger clocks and mechanisms. Priory Clock Oil is a medium-viscosity mineral oil designed for clock movements and watches.
It is a high-viscosity mineral oil formulated for lubrication and protection of larger clock mechanisms.
The stated pour point is -38°C, giving the oil excellent low-temperature performance.
Yes. The formulation incorporates corrosion inhibitors designed to provide protection against corrosion.
Yes. The oil provides anti-wear performance and is designed as a long-lasting lubricant for larger clock mechanisms.
Yes. Its low pour point of -38°C gives it good low-temperature performance.
The oil has a natural resistance to the formation of deposits at higher operating temperatures and is designed for long-lasting lubrication.
Only a small amount should be applied to the appropriate lubrication points. Avoid over-oiling the mechanism.
Use a suitable fine oiling nib on the bottle to apply a small, controlled amount to the lubrication points specified for the clock movement.
It should not automatically be substituted for a lighter clock oil. Turret Clock Oil is specifically intended for larger mechanisms where a heavier viscosity is appropriate.
It is available in 50ml and 100ml sizes on the current product page.
Push down on the lid while twisting it anti-clockwise at the same time.
No. This oil is a high-viscosity oil intended for larger mechanisms. A suitable watch or clock oil specified for the particular movement should be used instead.
Important: Always use the correct lubricant and viscosity for the particular clock mechanism. Apply oil sparingly and follow the manufacturer’s lubrication requirements where available.
