If you're new to watches, most especially to automatic types, there are certain things you need to know. This page is a guide to the general use and care of watches.

Automatic watches. These watches run when a coiled spring inside the watch unwinds. A moving part called a rotor spins in the back that winds this spring for you. You can also manually wind this spring by turning the crown clockwise.

The Nereid has a display caseback that displays the rotor

Running time. The watch will run for as long as the spring can unwind. The standard duration is 40+ hours if the spring is fully wound. There's no need to fear over-winding the crown as there's a feature that acts as a safety mechanism.

Some old watches, especially those that has to be manually wound, do not have this safety mechanism. So forcibly winding a watch can damage the movement.

Push/pull crown.  This is the basic type of crown. In its default or base position, you can manually wind your watch. You can adjust the time and date by pulling it at different lengths and turning in a specific direction.

Screw-down crown. This feature are for watches that need better water resistance and to prevent the crown from being vulnerable to water. 

If your watch has this type of crown, you need to unscrew it first before operating on it. When fully unscrewed, the crown will disengage and then it can function like a push/pull type. You can then screw it back after you are done. You may need to slightly press it while turning to be able to have it engage the screw treads.

Water use. Make sure the crown is in its base position before doing so, or if it's a screw-down crown, make sure it's tightly screwed back in.

Care and maintenance. Mechanical watches generally need inspection and re-oiling every five years to make sure it's in top condition. If you use your watch near water or high humidity environments, a yearly visit to your watchmaker would be good to inspect its water resistance.

Other useful tips:

  • Cautionary use. Even though watches are resistant to water, they are not water proof. Make sure to take it off when it doesn't have to be exposed to water
  • Chemical exposure. Chemicals can eat through the gaskets which help seal the watch. Gaskets are located around the crown stem, top crystal, and caseback. Common chemicals that may affect the integrity of gaskets are chlorine in swimming pool and even soap. They may not affect the gaskets right away, but extended exposure can make them brittle and less functional
  • Magnetism. Keep the watch away from magnetic sources. These can affect the accuracy of your watch. Such items are pretty common, like refrigerator magnets and sound speakers. If you suspect that your watch is going too fast or too slow, have it tested by a watchmaker to see if it's demagnetized. Don't worry, it's an easy process and should be done pretty quick.

Additional care. As part of caring for your watch, each has a warranty to help you should there be issues with your watch. See our terms for warranty here.
