Functioning of the watch
What are the precision tolerances of our mechanical watches?
The accuracy of the watch depends on the movement and individual habits of the wearer. The majority of mechanical watches (excluding certified chronometers) have average precision tolerances of between -10/+30 seconds per day. To earn the title of chronometer (see question relating to chronometers), the mechanical movement's average precision must be between -4/+6 seconds per day.
What are the precision tolerances of our quartz watches?
The precision tolerance of quartz watches is around -0.5 to +0.7 seconds per day (excluding certified quartz chronometers). Exposure to significant variations in temperature can have a slight effect on quartz movements.
How much is the power reserve of our self-winding mechanical watches and how do they work?
The power reserve of a self-winding watch depends firstly on the type of movement. When fully wound, the movements of our watches have a power reserve of between 36 and 80 hours. The power reserve also depends on the wearer's individual habits and activity. As an indication, 10 to 12 hours' wear should be sufficient to generate a power reserve of 20 hours or more, which ensures that the watch will continue to run throughout the night.
What is the difference between a chronograph and a chronometer?
A chronograph is a timepiece which, in addition to displaying the time, is equipped with a stopwatch mechanism to measure and record elapsed time. Depending on the model, the measured time is shown either by an analogue display with an hour, minute, second and even a 1/10 or 1/100 second hand or by a digital display. A chronometer is a watch that has obtained an official rate certificate from the COSC (Contrôle Officiel Suisse des Chronomètres), which certifies that the movement has passed a range of precision tests in different positions and at different temperatures over a 15-day period. Certification can be granted both for mechanical and quartz movements.
Can Mido watches be worn in the water?
Mido watches are designed to be water resistant to a pressure of 3 bar (30m/100ft), 5 bar (50m/165ft), 10 bar (100m/330ft) or 20 bar (200m/660ft), as indicated on the case back. Watches are pressure tested in a laboratory by means of tests conducted at various pressures corresponding to the pressure experienced by a swimmer or diver sitting still at various depths. However, many water-based activities involve a lot of movement and other environmental changes which exceed the boundaries of the tests conducted and may therefore affect the water resistance of a watch. A watch's water resistance cannot be guaranteed indefinitely, as it may be affected by ageing gaskets or an accidental impact to the watch. As stipulated in our Watch care section we recommend that you have the water resistance of your watch checked once a year by an approved service center. We also recommend that you do not under any circumstances open the watch yourself and do not adjust the time-setting crown and/or pushers (buttons) when your watch is underwater. Similarly, check that the crown is in position 1 (pushed in) or screwed down (depending on the model) before you enter the water.
What is the difference between a self-winding and a manual-winding movement?
Both types of movement are mechanical movements, but are wound in different ways. Manual-winding watches must be wound every day by hand using the crown, whereas self-winding watches are wound by an internal rotor which responds to wrist movements.
What is a unidirectional bezel and how can it be used for deep-sea diving?
A bezel is an adjustable ring on the case, often used to record additional data, such as the duration of an event or to read the time in a second time zone. A bidirectional bezel can rotate in both directions, clockwise and anticlockwise. A unidirectional bezel only turns one way to prevent it accidentally turning in the wrong direction and therefore giving a false reading. When measuring diving time, for example, any impact or false manoeuvre can only reduce the pre-set limits, preventing the user from having an exaggerated interpretation of air or decompression time. To use a unidirectional bezel for deep-sea diving, place the bezel's main indicator (initially positioned at 12 o'clock) at the projected time for the end of the dive. When the minute hand meets the main indicator, the diving time will have been reached. For example, for a 30-minute dive starting at 15:00, align the bezel's main indicator with 15:30 (at six o'clock) just before diving. The minute will take 30 minutes to reach the bezel's main indicator, thereby indicating remaining diving time.
How often does a watch need to be serviced?
Like any high-precision instrument, a watch needs to be serviced regularly to ensure optimum functioning. The servicing frequency depends on the model, the climate and the care you take of it. As a general rule, we recommend that you have a service carried out every four to five years by one of our authorized service center.
What is the difference between a partial service and a complete service?
A "partial" service consists mainly in a battery replacement for quartz watches or an adjustement of the rate for mechanical watches. In addition, the replacement of spare parts guaranteeing the water resistance are also included in this service. A service becomes "complete" when interventions on the movements turn out to be necessary (replacement of worn components and oils). All operations of the partial service are also included in the complete service.
Where can I have my watch serviced?
All servicing of your watch must be carried out by one of our authorized service centers. Any service not carried out by an authorized service center will void the warranty. A complete list of service centers is available in the Customer Service section.
Can my watch be serviced and do you have the spare parts?
Servicing of your watch depends firstly on the availability of its components. From the date production of your watch ceases, we guarantee the availability of spare parts for a minimum of 10 years, and up to 20 years for gold watches. If production of a particular part is haltered or suspended for any reason, we reserve the right, at our sole discretion, to offer an alternative solution. We will also do our utmost to maintain collector's pieces and jubilee watches.
How much does it cost to service my watch?
The prices indicated in the Customer Service section should be considered as indicative. This is because the law in many countries prevents the imposition of retail prices. Each independent authorized service center is therefore free to set its own service prices. The recommended retail prices stated on this site are nevertheless valid in countries with an official service center belonging to the Swatch Group Ltd.
What does the sales warranty cover?
All our watches are covered by a 24 month sales warranty from the date of purchase. The warranty conditions are provided in the warranty booklet supplied when the watch was purchased or in the Customer Service section.
What does the service warranty cover?
Services carried out by an authorized service centre are covered by a 24 month service warranty on the work carried out. This warranty does not cover normal wear and tear and damage caused by accidents or lack of due care. This warranty is void if any work is carried out by a third party that is not authorized.
Can I order spare parts directly from Mido?
Only service centres meeting the strict criteria relating to equipment and technical skills are supplied with original Mido spare parts. This allows all customers to enjoy a service in line with Mido's standards of excellence.
What should I do to ensure that my watch continues to provide excellent service for many years?
Magnetic fields: Do not expose your watch to intense magnetic fields such as loudspeakers or refrigerators and other electromagnetic appliances. Shocks: Whether thermal or other shocks, avoid them. In the event of violent shocks, please have your watch checked by an authorized service center. Crown: Depending on model, push or screw it in carefully to ensure that no water enters the mechanism. Cleaning: For metal bracelets and for all water-resistant cases use a toothbrush with soapy water and a soft cloth for drying. Chemical products: Avoid direct contact with solvents, detergents, perfumes, cosmetic products etc., since they may damage the bracelet, the case or the gaskets. Temperatures: Do not expose your watch to sudden temperature changes (exposure to sunlight followed by immersion in cold water) or extreme temperatures over 60C (140F) or under than 0C (32F).
How to clean your watch in this period of Coronavirus?
Dear customer, In the wake of the Covid-19 coronavirus pandemic, hygiene precautions need to be stepped up in everyday life. The same applies to your watch. Below you will find our tips, which can be followed alongside strict hygiene measures, such as washing your hands frequently. On parts made of metal, silicone, plastic, sapphire (the watch crystal or the back of specific watches): Wipe with a lint-free wipe impregnated with a hydro-alcohol solution, usually based on methylated spirits (a solution containing over 70% alcohol). Be sure to concentrate on the moving parts (e.g. bracelet links) and uneven areas. Then leave it to dry, without wiping the watch. The wipe is disposable and must be thrown away after use. For leather, rubber, cloth and plastic straps with decoration, as well as polymer watch crystals or case backs : Wipe with a lint-free wipe soaked in water with a little soap added. Avoid using an alcohol solution, which could cause permanent damage to these materials. Be sure to concentrate on the moving parts (e.g., bracelet links) and uneven areas. Then leave it to dry, without wiping the watch. The wipe is disposable and must be thrown away after use. These measures cannot entirely guarantee a level of disinfection that is capable of eradicating viruses and germs, especially on delicate materials that cannot be cleaned with an alcohol solution, such as leather. However, they will make a contribution to maintaining a hygienic environment.
What does PVD mean?
PVD stands for "Physical Vapour Deposition". It is a process performed under vacuum which deposits microscopic particles on the products by ion bombing or sputtering, to form a protecting coating on their surface with a specific colour. Very thin layers (1 μm) of impurity-free components can be obtained which possess high levels of hardness and hypo-allergenic qualities.
What is titanium?
Titanium is a metallic element found in the earth's crust. The element occurs as a bright, lustrous metal or a silver-grey or dark-grey powder. Titanium is 50% lighter than steel and very corrosion-resistant. When exposed to air it forms a hard oxide film which resists corrosion and salt water. Titanium is hypo-allergenic since it is nickel-free.
