After-sales service is one of Les Ambassadeurs' strong suits. In every boutique, our experts - a team of master watchmakers - handle repairs and servicing in specially equipped workshops, which customers can view from behind glass. This level of transparency enables customers to get an idea of what exactly happens to their watch. In this way, professional, specialised service is the key to successful after-sales service.
Every watch requires a certain amount of care and monitoring a er purchase. Regardless of whether your watch is an everyday favourite or just for wear on special occasions, everyone hopes that their watch will last for as long as possible. To help make this possible, we have worked together with our team of experienced watchmakers to compile a selection of tips and helpful advice for you. Should you have further questions or suggestions, please feel free to contact us at any of our boutiques using the respective contact details provided.
01. YOUR WATCH AND DOCUMENTATION
A mechanical watch should be worn regularly; otherwise the lubricating oils inside the watch can clump, possibly damaging the movement of the gears and reducing the accuracy of your watch. Protect your timepieces from moisture and direct sunlight. Variations in temperature shorten the life span of the movement and age the strap. If you do not wear your watch regularly, we recommend you fully wind the power reserve once to twice a month to keep it running. Another way to keep the movement mechanism wound is to activate the complications (e.g. change the date, or start/stop or reset the chronograph).Never force the watch: overwinding will not increase the power reserve. Stop winding as soon as you feel resistance in the crown.
02. SELF WINDING WATCHES
The distinguishing feature of a self winding (automatic) watch is an oscillating weight (rotor) that can be seen or heard rotating at the case back. There are two ways to wind an automatic watch. The first method is self winding, which is selected by the motion of the wrist when the watch is running normally. Depending on your activity level, allow half a day for your watch to self wind. If the watch has stopped, it can be wound using the crown (15 to 20 turns). Thee second option is to use an automatic watch winder. More sophisticated watch winders can be conjured to the appropriate direction and speed. The correct settings for your watch will be recommended to you by our sales advisers.
03. MANUAL WINDING WATCHES
A manual winding watch has no oscillating weight. When fully stopped it can be restarted only by winding the crown. Continue winding your watch until it is fully wound, i.e. even a er the seconds hand starts ticking. However if you feel the least resistance in the crown, stop winding immediately, as to continue at this point could cause irreversible damage to your watch without increasing its power reserve. If you feel no resistance, your timepiece is equipped with a mechanism that safeguards against overwinding. The larger the power reserve of your watch, the longer it will take to wind. Thirty to forty turns at moderate speed will usually suffice. Do not rush the operation; when you wind the crown,
04. QUARTZ WATCHES
A quartz watch is powered by a non-rechargeable battery specific to the model. Battery life is generally two to three years, irrespective of your level of physical activity. Regular use of any complications in your watch (such as the chronograph or alarm) may reduce the battery life. If you do not wear your watch for a certain period of time, the chemical stability of the battery may become compromised. In such an event we recommend that you consult the watchmaker to ensure that there is no damage to other components in the movement. Avoid exposing a quartz watch to sunlight as the battery is sensitive to high temperatures. Also note that only a certified watchmaker can replace the battery of your watch.
05. ADJUSTING THE WATCH
Adjusting the watch must be carried out according to a specific procedure which should be followed in order to avoid damaging the complications. Quartz and mechanical watches with only hours, minutes and occasionally seconds follow no particular instructions. However, this is not the case for adding a date or any other complication. To set the date, it is not recommended to attempt to turn it back (and additionally, very few calibres allow this). This means you have to move forward to the day before the desired date, then advance the hours and minutes to get the current date. Given that a dial indicates 12 hours, it can be difficult to know if it is midday or midnight. To do this, simply move the hands:
Magnetism is an invisible malady that can cause serious damage to a watch. When a watch is magnetised, the first part to be affected is the balance spring. This is the heart of a mechanical watch and moves in time with the ticking of the watch. Also known as the hairspring due to its minuscule thickness, this component is sensitive to the pull of the Earth’s gravity. Magnetism has a broad- reaching impact on the watch. It heavily destabilises the balance spring, and seriously – although not irreversibly – interferes with the accuracy of the watch. Keep your watch away from the clasps of bags, mobile phone covers, speakers, tablets, laptops, security portals, radios,
07. PROTECTING THE WATER-RESISTANCE OF YOUR WATCH
The water-resistance of a watch is measured in metres or atm. In terms of water-resistance 1 atm is equivalent to 10 m, 2 atm is equivalent to 20 m, and so on. Please note that metres do not correspond to the equivalent underwater depth. A watch with water-resistance less than 5 atm should not be immersed in water. A surface splash should not affect the water-resistance, but the impact of submersion would risk damaging the timepiece.
If you plan to wear your watch day-to-day when washing your hands and showering, we recommend a water-resistance of at least 5 atm.
08. SERVICING YOUR MECHANICAL WATCH
A mechanical watch beats at over 500,000 vibrations a day, activating between 200 and 250 components one by one – some of which are no thicker than a strand of hair – and all adjusted down to the micrometre. Given this, we can better understand why a mechanical watch needs to be serviced regularly. It is generally recommended to do so every three years. By this time, a conventional watch will have totalled over half a billion vibrations.
Lubrication is the key element for the proper functioning of any kinematic chain. Once the components have been dismantled, the watchmaker cleans them, thereby eliminating any build-up of solidified oil that may have occurred. The components are then reassembled. Oil and grease are added throughout reassembly.
09. YOUR WATCH STRAP
Your watch strap requires specific care appropriate to the material. However a common rule for all non-metal straps is to avoid prolonged exposure to the sun, which may taint or crack the natural material and fade the colour.
Solid metal bracelets (gold, platinum, steel, titanium and combinations of metals) can be cleaned at home with tap water and a little detergent. Rinse with water. A watchmaker will carry out an ultrasonic clean to eliminate all impurities.
10. WATCH WINDERS
An automatic watch will stop if not worn for 42 hours or longer since motion is needed to activate the self winding mechanism. A watch with only hours and minutes can be easily set a er stopping. However it is tedious to set a watch with complications such as the date, time or month, the day of the week or a perpetual calendar. A watch winder is a convenient solution to keep a watch from stopping. We recommend watch winders which can be conjured according to two variables: winding direction and duration. If your winder does not offer bi-directional winding, you will need to be able to choose the winding direction that is appropriate for your watch.
