Should an automatic mechanical watch be rewound manually?

Many Baume & Mercier watches are equipped with automatic mechanical movements.

An automatic or self-winding mechanical watch has a sophisticated mechanism which winds itself automatically thanks to the movements of the wearer's wrist. Nevertheless, if you have not worn your watch for several days, it will stop or will have insufficient power reserve to ensure optimal accuracy. In this case, before using it again, we suggest you wind it manually with about 20 clockwise turns of the crown to ensure that it will operate perfectly in all conditions. After wearing your watch for several hours, depending on your activity level, the watch will be perfectly wound.

Special recommendations: 

- The efficiency of the self-winding process is directly linked to the motion of the wearer's wrist. In case of insufficient movements, the watch may stop even while being worn. In this case, we recommend to wind the watch manually with about 20 clockwise turns of the crown.

- The watch should be removed from your wrist before winding it. This ensures the crown stem remains completely straight during winding and avoids the risk of damaging the crown or the movement.

- Even if your watch is not worn for several months we advise you to regularly wind it manually. This will prevent the oils from either congealing or flowing over the shafts of the movement.

- For watches equipped with Baumatic movement:  to ensure a sufficient power reserve before putting your Baumatic watch on the wrist, note that 50 turns of the crown are necessary (instead of 20 for standard movements), given its higher power-reserve.

When should a hand-wound mechanical watch be wound?

We suggest you wind your watch every day, preferably in the morning, by turning the crown until it resists. Once this point has been reached, do not force the crown any further as there is a risk of seriously damaging the movement.

The watch should be removed from your wrist before winding it. This ensures the crown stem remains completely straight during winding and avoids the risk of damaging the crown or the movement.

Finally, even if your watch is not worn for several months, we advise you to regularly wind it. This will prevent the oils from either congealing or flowing over the shafts of the movement.

What is the difference between a chronograph and a chronometer?

A chronograph is a watch which can measure and display time intervals. A chronograph model generally contains a central seconds-hand for counting seconds, a counter for totaling minutes and another for totaling hours.

A chronometer is a high-precision watch displaying seconds whose movement has been controlled over a period of several days, in different positions and at different temperatures, by an official neutral institute. Only mechanisms that have satisfied the criteria for precision are issued with an official chronometer certificate. In Switzerland, the Official Swiss Chronometer Testing Institute (COSC) is the only insitute who can issue such certificates.

Why is my mechanical watch less accurate than a quartz watch?

The difference arises from the fact that the two movements are quite different.

A quartz watch is extremely precise due to its high frequency of vibrations (32 kHz).  Its precision (fast or slow) deviates by approximately 1-2 seconds per week (1-2 mintutes per year).

In comparison, a mechanical movement (self-winding or hand-wound) contains an hairspring  with an oscillating frequency  between 2.5  and 4 Hz, corresponding to an accuracy of 1- 2 minutes per week. Furthermore, the precision of a mechanical watch can also be affected by a variety of factors, including impact, the aging of the oils, significant temperature fluctuations, magnetic fields and wearer activity.

What are your recommendations and instructions for taking care of my watch?

Recommendations for taking care of your Baume & Mercier watch are available in the Care recommendations section of our website

How long is a Baume & Mercier watch guaranteed for?

Your watch is guaranteed for 24 months from the date of purchase from an authorized Baume & Mercier retailer. For more information, please refer to our Warranty section

Where to buy an authentic Baume & Mercier watch?

Authentic Baume & Mercier watches are sold exclusively, through our network of authorized retailers around the world. In some countries, we also have opened an official Baume & Mercier e-boutique to better serve our customers. This assures you are investing in a genuine Baume & Mercier timepiece and that it is not counterfeit, modified or a second-hand item presented as new merchandise. 

Only watches purchased through an authorized retailer are accompanied by a Baume & Mercier International Guarantee.

You may find details of these retailers on our Store Locator

Why does a watch need regular maintenance?

Your Baume & Mercier watch is a high-precision instrument working continuously 24 hours a day, that needs regular maintenance to maintain its precision and water-resistance over time.

The interval between services may vary, depending on the use of the watch as well as the environment in which it is worn.

The water resistance can, for example, be affected by the natural aging of the gaskets but also by regular use of the winding crown, shocks, and other factors including perspiration, use of cosmetics and changes in temperature.

We recommend a water-resistance check every year and a complete service performed every 3 to 5 years by one of our service centers.

Note for watches equipped with a Baumatic movement: new lubricants allow for the intervals between services to be extended (5 to 7 years instead of 3 to 5 years).

Where can I have my watch examined and repaired?

If your Baume & Mercier watch needs a service, we invite you to drop off your watch at one of our service centers or at an authorized retailer who will take care of sending it to one of our service centers.

Alternatively, in some countries (United States, France, Hong-Kong, Japan and Australia), you can also directly send your watch to our regional service center. If you are interested in this service, please visit our dedicated section by clicking on one of these countries and/or contact us so that we can explain you the full process and send you a Shipping Kit to securely pack your watch.

Your watch will then be handled by a certified watchmaker benefitting from specific tools and original components.

How long does it take to receive an estimate?

When you drop-off your watch at an authorized retailer, you should be given an approximative pre-estimate including price and leadtimes for the service required. Then, if you agree, your watch will be sent to one of our service centers where a full diagnosis will be performed by one of our watchmakers who will determine the service and parts to be replaced taking your initial request into consideration.

You will then receive an official estimate within 1 week from receipt of your watch by our Service Center (4 weeks if the watch needs to be repaired in Switzerland). Of course, no service will be carried out without your prior approval.

How long does it take to service my watch?

In principle, spare parts for our contemporary watches are always available and the time required for service by our skilled watchmakers depends only on the type of service to perform: Battery service (approx. 1 week ), Water-resistance Service (approx. 4 weeks) or Complete Service (approx. 5 weeks).

For vintage watches, spare parts are not always immediately available in stock in all countries, and this can cause an extra delay. In addition, components such as cases, dials or bracelets are sometimes out of stock and have to be re-manufactured, further extending the delay. Lastly, certain watches must be returned to our Baume & Mercier watchmaking workshop in Switzerland to be exclusively repaired by our specialized watchmakers in charge of the restoration of the vintage pieces, and time required will be longer than for a standard service (minimum 8 weeks).

Is a service carried out in an authorized Baume & Mercier After-Sales Service Center as good as a service carried out by a Richemont regional platform or by Baume & Mercier watchmakers in Switzerland?

All the certified watchmakers working at an authorized service center have the competence and experience required to perform high-quality work on contemporary watches (less than 20 years old). Moreover, they are regularly trained by Baume & Mercier and use the same specific tools and original components used by Richemont regional platforms or Baume & Mercier watchmakers in Switzerland.

How long will the battery in my quartz watch last? And when should I change the battery in my quartz watch?

Battery life is generally between 3 and 6 years, depending on the watch model.

The majority of our quartz watches with a central seconds hand, come equipped with a system to indicate a low battery (EOL – End of Life): approximately two weeks before the battery will stop, the central seconds hand will begin to jump every four seconds, signaling that the battery must be changed.

You should never leave an exhausted battery inside the watch to avoid the risk of leakage which could damage the movement.

We recommend the battery be replaced by a certified watchmaker who will also check water-resistance and movement condition of your watch.

For how long is the service intervention guaranteed after completion?

All Baume & Mercier watches we receive are handled with great care and serviced to the highest standards. After being serviced, it undergoes several controls, including an electronic wearing simulation during several days, to verify that it is running properly before it is returned to you.

Baume & Mercier provides a 12-month guarantee on all work carried out and parts replaced during the service.

Is my watch water resistant?

With the exception of a few specific models, including vintage ones, Baume & Mercier watches are water-resistant up to at least 30 meters. If a model’s water-resistance goes beyond 30 meters, the depth is indicated on the back of the case. 

When a watch is water-resistant, its movement is protected from dust, humidity and any risk of damage caused by immersion. As such, your watch is water-resistant in all usual circumstances of daily life: in the rain, the shower or while swimming. However, you should avoid subjecting your watch to high pressure water jets and protect it from knocks that may occur during the practice of intense water sports.

Note that the water-resistance of your watch is not permanently guaranteed. The gaskets that ensure water-resistance can be physically deteriorated by natural aging but also by regular use of the winding crown, shocks, and other factors including perspiration, use of cosmetics and changes in temperature.

It is the reason why we recommend a water-resistance check every year, preferably before a summer vacation.

Warning: 

When your watch is submerged in water, make sure that the crown is tightly closed (pressed or screwed-down, depending on the model), and do not press any of the push-buttons because water may enter into the case.

If you notice any condensation inside your watch, you must take it immediately to one of our authorized retailers or service centers.

 

Is a leather or rubber strap covered by the warranty?

Fair wear and tear of non-metallic straps or bracelets (leather, rubber synthetic polymer, etc.) is not covered by the Baume & Mercier International Warranty and you should arrange to have them replaced at your expense when necessary. 

If you wish to order a strap, please contact one of our authorized retailers or Contact us.

What is the expected lifespan of my rubber strap?

The life span of a rubber strap depends on the conditions of use and how often it is worn.

To conserve your rubber strap for several years, we recommend keeping it away from oils and cosmetics.  You should also  avoid prolonged exposure to sunlight and rubbing against clothing as it may cause discoloration (particularly in a white strap) or premature deterioration.

You may clean your rubber strap with soapy water.

If you wish to order a rubber strap, please contact one of our authorized retailers or Contact us.

What is the expected lifespan of my leather strap?

The life span of a leather strap depends on the conditions of use and how often it is worn.  For example, a strap is affected by the acidity of the skin, perspiration, temperature changes, long exposure to sunlight, skin creams, cosmetics...
Extreme conditions such as sports activities or immersion in water considerably reduce its durability.

If you wish to order a strap, please contact one of our authorized retailers or Contact us.

What is a magnetic field and how are they avoided?

Our environment is increasingly subject to magnetic disturbance from various sources that can affect the running of your Baume & Mercier watch. For this reason we recommend you avoid placing your watch near or in direct contact with magnets, electronic devices, magnetic handbag clasps, or magnetic iPad or iPhone covers.

A quartz watch may be affected when it enters a strong magnetic field but it will return to normal when it leaves the field. The disturbance therefore only lasts while your watch is within the field. 

A mechanical watch is also sensitive to strong magnetic fields. In certain cases, steel components of the movement may become magnetized, particularly the hairspring. In some rare cases, magnetized parts may stick together and cause the watch to run fast, or stop completely. In this event, demagnetization is required and should be performed at a Baume & Mercier Service Center (store locator).

Note for watches equipped with a Baumatic movement: thanks to the use of silicon and non-ferromagnetic elements for the sensitive parts of the movement (including the hairspring), the watches equipped with a Baumatic movement are resistant to everyday life magnetic fields (beyond 1,500 Gauss = 25x higher than to the current norms ISO 764 / NIHS 90.10).

Does the case or the bracelet of my watch contain nickel?

There is some nickel in the stainless steel used in Baume & Mercier watches. However, all the metal we use meets the European standard EN 1811 that sets the salting-out limit for nickel: Ni <0.5 mg/ cm2/ week. 

It is important to understand that sensitivity to nickel does not depend on the quantity of nickel present but on two factors:

• The closeness of contact between the skin and the nickel salted-out by corrosion

• The personal degree of allergy. Please note that people who are sensitive to nickel may show an allergic reaction when exposed to levels below the permitted limit.

Do the diamonds used in Baume & Mercier watches have a certificate of origin?

Our diamond-set models are accompanied by an official Baume & Mercier document indicating the quality and caratage of the diamonds for that reference.

Are they ethical diamonds?

Yes. At Baume & Mercier we buy our diamonds in conformity with the Kimberley Process Certification Scheme and the World Diamond Council Guarantee System, set up to end the trade in "Conflict Diamonds/ Blood diamonds" and to keep them out of the supply chain. We only buy diamonds from suppliers who respect these systems.
