Trust is, and will forever remain, at the core of the ongoing relationship between its customers all over the world and Hamilton. Today around 4'000 official Hamilton retailers attest the genuineness of every Hamilton watch and provide expert and dependable after-sales servicing, thanks to their expertise and professional skills, and to specially adapted equipment. Hamilton LTD disclaims any relationship to, or responsibility for, any timepiece or other item bearing the Hamilton name, brand, logotype or symbol offered for sale by anyone not being an official Hamilton retailer. Purchasing such an item from an unauthorized party is therefore at the buyer's sole risk, particularly in the case of counterfeit or substandard products and in case of products purchased on the Internet. No explicit or implicit warranty or servicing or any other obligation shall ensue for Hamilton or for any of its authorized representatives for products sold by unauthorized parties and not accompanied by a duly stamped Hamilton international warranty booklet. For the above reasons and in your own interest, you are invited to acquire only genuine Hamilton timepieces available exclusively from a legitimate Hamilton official retailer. Thank you.

You can be sure you are buying a genuine HAMILTON watch if you follow these steps:

• buy a HAMILTON watch only from authorized HAMILTON retailers
• ask for the guarantee, duly completed with date, watch reference and retailer's full name and address.

A battery life varies usually from two to five years depending on the type of the watch, its dimensions and the quantity of energy requested by the different functions. For instance, a chronograph will have a higher energy consumption than a watch indicating the hours and minutes only.
Most HAMILTON watches feature a power reserve indicator: When the seconds hand starts jumping every four seconds, it is time to have the battery replaced by a HAMILTON qualified watchmaker.

Like any high-precision instrument, a watch needs to be services regularly in order for it to work perfectly.
Obviously, we cannot indicate the intervals for such servicing, given that it depends entirely on the model, climate and the care taken by the watch's owner.
As a general rule, it is between 3 and 4 years, depending on the use of the watch.

For technical and quality reasons, we do not deliver individual spare parts directly to our customers.
The HAMILTON World Customer Service Centres are available to all customers and offer a professional service, carried out in accordance with HAMILTON's high quality standards.

HAMILTON watches are water resistant to 30, 50, 100, 150 or 200 metres which is indicated on the case back.
Water resistance of watches is rated based on laboratory pressure tests comparable to a swimmer or diver sitting still at that pressure level. However, many water-based activities involve a lot of movement and other environmental changes. These exceptions to how the watch was rated may undermine the water protection features of a water resistant watch.
In particular, the water resistance rating of a watch does not take in to account the ability of the watch to STAY water resistant as it ages. Therefore, the water resistance of a watch cannot permanently be guaranteed. It may be affected by ageing of gaskets or by accidental shock to the crown or pusher. As stipulated in our service instructions we recommend you to have checked the water resistance of your watch once a year by an approved HAMILTON service agent. Do not under any circumstances open the watch yourself.
Make sure not to activate the time-setting crown and/or the pushers while the watch is under water and make sure that the crown has been pushed in or screwed down.

• Magnetic fields: Do not expose your watch to intense magnetic fields such as loudspeakers or refrigerators and other electromagnetic appliances.
• Bathing in the sea: always rinse your watch with fresh warm water afterwards.
• Shocks: Whether thermal or other shocks, avoid them. In the event of violent shocks, please have your watch checked by a HAMILTON approved 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 60°C (140°F) or under than 0°C (32°F).

The accuracy of the watch depends on the movement and on the individual habits of the wearer and can therefore vary. A qualified HAMILTON watchmaker can adjust the precision of a watch to within the HAMILTON tolerances.
The majority of watches that do not have a chronometer certificate have average precision tolerances of between -10/+15 seconds per day. To earn the title of chronometer, the mechanical movement’s average daily variation in rate must be between -4/+6 seconds per day

The difference between these two movements is the way in which the watch is wound.
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

All HAMILTON quartz movements are produced in accordance with HAMILTON’s highly renowned procedures and quality standards.
Ambient temperature may affect the precision of quartz movements, which can lead to variations of between -0.5 and +0.7 seconds per day.

All HAMILTON diamonds are Top Wesselton, VVS. They have been purchased from legitimate sources not involved in funding conflict and in compliance with United Nations resolutions, as written in the credit card size Precious Stone Certificate.

Unfortunatly some spare parts get lost in our moving from America to Switzerland, so that is not possible to guarantee the repair of old Hamilton watches.
HAMILTON will do its utmost to ensure collectors' items and vintage watches can be repaired.
If it is not anymore possible to repair an old Hamilton we will be glad to make you a replacement offer.

The materials used by HAMILTON are subjected to severe tests in order to avoid allergies.
The stainless steel (316L) used by HAMILTON does contain a small amount of nickel, but does not release it and is therefore safe for allergy sufferers.
The only exception is for those who are hyper-sensitive to stainless steel. In this case, we recommend you to buy a watch which is made of titanium, gold or which is PVD coated

The value of an old clock is limited to that sentimentally value of the owner.
