Battery life varies usually from two to five years depending on the type of the watch, its dimensions and the amount of energy required by the different functions. If your watch has a seconds hand and it begins to jump in four-second intervals, the battery of your Hamilton watch needs to be replaced. This is an end of life indicator.
We recommend that you take your watch to an authorized Hamilton Service Center or Hamilton retailer to have your watch battery replaced as they have the necessary tools and testing equipment to carry out the work to Hamilton’s high quality standards.
A mechanical movement is a micromechanical high precision instrument that takes its energy from a mainspring which is placed in the movement barrel. This mainspring is charged either by an oscillating weight that winds the watch mainspring as you move (automatic) or by hand (manual winding).
If you do not wear your automatic / mechanical watch for a few days, it will stop working and will need to be reset.
Quartz movements take their energy from a battery and a synthetic quartz regulates them.
All Hamilton movements are produced according to the strict quality standards of the Swatch Group.
You can be sure you are buying a genuine Hamilton watch if you buy it from an authorized Hamilton retailer or a Hamilton online store. To see the full list of official distributors please visit our store locator.
Your watch will be delivered together with an international warranty, duly completed, stamped and signed by the official Hamilton dealer..
The accuracy of a watch depends on the movement and the individual habits of the owner and can therefore vary. A qualified HAMILTON watchmaker can set the accuracy of a watch within the set tolerance. Most watches that do not have a chronometer certificate have an average course deviation of -10/+15 seconds per day. To be called a Chronometer, the mechanical watch mechanism must have an average course deviation of -4/+6 seconds per day.
