Domestic clocks are one of the most ignored watches in the entire household. We make sure that our wrist watches are well maintained with good servicing, battery changes and of course lots of lubricating. But domestic watches are practically ignored till the battery runs down. Even then, we just replace the battery without getting any servicing or lubricating done on it. That means that the watch continues to run without any care or oiling till they finally expire and die! But just like wristwatches, domestic watches need to be maintained well too with regular cleaning and lubrication and care. Clocks are larger than wristwatches so a little too much lubrication is OK here.
But still there are rules to be followed in lubrication and care of clocks like-
* Try to use just a single drop of oil in the watch works to make the watch remain on time. These are bigger watches so they don’t really require you to be precise but it’s a good idea if you are. Carriage clocks require a smaller amount while long clocks and grandfather clocks require much more.
* Try not to scrape the oil pots while oiling watches as it scrapes up unnecessary settled grit into the workings of the clock. This is especially true of incalite pots. Use only fresh oil and discard any which has more than five years on the packing date on the seal; protect the oil you are using by storing it at room temperature and away from direct light. An ideal temperature would be about 15 to 20 C or as stated by the manufacturer of the clock. There are several points on a domestic clock where you can oil them and the oil will them spread to all over the clock workings. Good places to apply lubrication are at oils sinks or pivot holes, escapement pallet faces, weight pulley bearings and points of contact between different parts of the mechanism.
* Make sure you do clean the mainspring and refit the watch springs after you have oiled the domestic wall clocks. You can also apply heavy grade mineral oil around the edges of the barrel cap. Capillary action will make sure that the oil spreads all over the mechanism.
* Do not lubricate or oil pinion leaves and gear teeth, as they will slip while revolving. Another place to be careful of is the ratchet and the great wheel arbor in the main clock facings.
* The frequency of oiling depends on how frequently you use the clock and the location it is based in. Synthetic oils are very stable and do not deteriorate but non-synthetic oils do. The residue leaves a gummy deposit in the watch that can destroy a good watch.
* Contamination with dust will however really cause a tremendous amount of wear on the clock and that can damage the mechanism. Reapplication of oils is fine after the old one has been wiped off.
But do make sure that you do service the watch at least every two years to maintain optimum working conditions.
