A watch is not water resistant unless otherwise indicated on the dial or case back. Furthermore, the water resistance of a watch cannot be permanently guaranteed. It can be affected by the aging of the seals or by an accidental impact on one of the components ensuring water resistance such as the crown, the pushers and the crystal.
Before using your watch in water, always ensure that the crown is firmly closed and do not press the pushers underwater. Screw down the crown carefully to prevent moisture from entering the movement.
Have the tightness of your Tellus checked regularly by our Maintenance Services.
Magnetic fields, ubiquitous in modern technology, can alter the accuracy and reliability of your watch by speeding up or slowing down the movement. In fact, electromagnetic fields risk affecting an essential part of your watch: the hairspring, which is a small spring used to maintain the regularity and frequency of oscillation. Avoid placing your watch near electronic devices such as magnets, speakers, mobile phones, televisions, tablets, computers, microwaves, induction hobs, etc.
If you notice that your Tellus is magnetized, we recommend that you contact our Service Services.
When cleaning your watch, avoid using chemical products such as soap, detergents, cosmetics and perfumes, as they could damage the case or strap of your watch over time, especially leather straps.
Instead, use a microfiber cloth or soft-bristled toothbrush in lukewarm water and gently brush the top of the watch face and metal strap. Avoid using soap, as it can leave particles in small spaces.
If necessary, regularly check that the stones set in your timepiece are perfectly in place. Use a soft cloth to wipe your watch.
For those who own several watches and like to alternate them on their wrist, it's not necessary for one watch to run all the time. A mechanical or automatic watch needs to run from time to time. Simply wind your Tellus once a month, or even every two months.
Stainless steel is an alloy of several metals. As a result, the stainless steel in your watches is never completely rustproof, and its resistance to corrosion may be reduced over time.
We therefore recommend that you rinse your watch in tap water after contact with seawater or swimming pool chlorine, to prevent salt residues or other contaminants from affecting your watch or its mechanism.
Avoid wearing your watch during strenuous or violent sporting activities such as tennis, squash, mountain biking, etc., which may result in shocks to the body or wrist.
Leather is a living, permeable material that should not be exposed to greasy substances, cosmetics and/or chemicals such as perfumes or moisturizers. Your leather strap should be regularly cared for with special leather care products to keep it supple and shiny for as long as possible.
Do not swim with a leather strap, and generally avoid contact with water and humidity to prevent discoloration or deformation. Also, avoid exposing the strap to sunlight for prolonged periods to preserve its color brilliance.
Metal straps are more robust and require only light maintenance every six months or so. We recommend simply brushing the strap with a soft brush soaked in water. Then polish your Tellus bracelet with a soft microfiber cloth to restore its shine.
Extreme temperatures can damage the internal mechanisms or external parts of a watch, adversely affecting its performance without you even realizing it.
Extreme heat can affect the hands of your watch, deforming them even slightly, and extreme cold can alter the seals. Worse still are extreme temperature variations. Among other things, these can affect the viscosity of the inner oils and impair the smooth running of your watch.
So avoid exposing your watch to extreme temperatures.
