Basic Care of Watches

If we want our Casio watch last us a lifetime is important to good care and maintenance. Quartz watches generally require a fairly simple basic maintenance actually, we can make ourselves at home if we persist.

It is advisable to clean and dry the strap and case with a soft cloth periodically to prevent dirt from collecting on the joints.

If we are to stop using our clock for a period of time, we must remove the battery and store without it, since the oxidation of battery components may affect the other components of the clock.

Every 3-4 years, coinciding with the change of batteries, this article advises that our watchmaker conduct a review of the tightness of the component to check that everything is correct and correct small gaps.


The belt cleaning is basic to our watch, not so much for its operation and management, although the belt is one of the parts of the watch to which we give less importance.

Cleaning steel belts

To clean a steel belt (and metal in general) must be done with plenty of soapy water and dry well. Do not let dry in the sun as it can be oxidized.

From time to time it is necessary to remove this type of straps to lubricate. Once washed and well dried, we use low density oil, never the usual oils we use at home because these oils oxidise the metal. Nor is it advisable to use 3 in 1 or oils Spray as engrasaríamos disservice clock and all other components. A little tip is to pour oil on the belt as drip of a needle or pin.

Belt cleaning resin

It is advisable to remove the belt. Clean with soapy water and dry thoroughly because if moisture is left can acartonar and start to crack. If we get to acartonar, a good practice is to dip the strap in silicone oil to fully recover its elasticity for at least two weeks. Once this period of time, re-clean with soapy water and dry thoroughly.

Cleaning leather belts

They are the most sensitive in terms of maintenance straps. We need a soft cloth and a special cleanser for oily skin. Failing that we could use a specific moisturizer, but be careful to test it before in an inconspicuous area of ​​the belt in case the deteriorates.


When performing an internal cleaning your watch, it is advisable to take it to a specialist as very delicate pieces can be handled and break the clock if we are not too clear about what we do.

If we see ourselves with sufficient knowledge to do it ourselves, the best product for cleaning internal clock is isopropanol, an easy to get at any drug store and much less corrosive than similar. Be very careful with this alcohol does not touch parts of rubber or rubber.

  • For analog clocks we disassemble the pieces carefully with special tools.Not directly oiling the gears and be careful not to overdo the oil, it is preferable to fall short, since removing excess oil will become an exceedingly difficult task.
  • Digital clocks for internal maintenance is much simpler, and is limited to replacement of the polarized filter the LCD.These filters can last about ten years under normal conditions, although life may decrease if exposed to intense sunlight for prolonged periods.


Over the years, on the screen of our watch Casio and multiple scratches caused by rubbing or simple dust motes in contact with the surface marks may appear. Leaving them as new is a daunting task, but there are some tricks you can try to leave it as close as possible.

Many models of Casio watches use plexiglass, a hybrid of glass and plastic having the advantage that it is virtually transparent and very pliable and resilient. Its great disadvantage, spider with astonishing ease. To polish this kind of glass we can use toothpaste and brush with very fine and soft bristles careful not to touch the box. Be careful when choosing toothpaste, do not serve us liquid pastes or microparticle teeth because they will scratch your screen even more.

If your watch has a Casio composed of mineral glass screen repair it is much more complex. The most common is to use sandpaper water and ceria or polish.

  • The first step is to use a water sandpaper grit 2000, passing through the glass gently in circles until the screen is matte and notes with your fingers that the screen is completely smooth.This can take time, so we recommend patience.
  • It is second step is polishing the screen, rubbing against Cerium oxide and circulate smoothly.After a few minutes we will see the screen of our watch has fully regained its luster and scratches are gone. Cerium oxide is a difficult material to get and to be handled very carefully, so for this step can also use polish.
