Q: Question says all... They both don't need batteries... Thats all i know O.o''

A: Good question. A lot of people thought that a kinetic watch is equivalent to an automatic watch. Exact fact: Nope, it is not equivalent, but similar.

I have gathered some information for you.

Seiko Kinetic is the first quartz watch powered by human movement, a development so significant it led to the application for more than 50 patents. The process uses an oscillating weight that is rotated by the movement of your wrist: this movement is transformed into a magnetic charge, and then into electricity, which is stored in a tiny capacitor or a rechargeable battery. A power reserve indicator will show exactly how much energy you’ve created.

Seiko Kinetic’s features:

1.Never needs winding
2.Never needs a battery change
3.Captures and stores energy for up to six months (most Seiko models)
4.Environmentally friendly

On the other hand, a Seiko automatic watch winds itself with the motion of your wrist, so you'll never need to change the battery. If the watch is worn daily, Seiko’s automatic mechanism will wind the mainspring automatically through normal wrist movement.

Seiko Automatic’s features:

1.Never needs a battery change
2.Stores ‘energy’ for 2-3 days
3.Environmentally friendly

As everyone's wrist movement is different, from non-active to active, it might wind the Seiko automatic watch's mainspring differently. For example, a person who loves to jog while wearing a Seiko 5 automatic watch will help in winding up the mainspring more and its power might last up to 3 days.

On the other hand, a person who sits in the office all day working with his computer might have less winding of the automatic watch’s mainspring and its power might last up to just a few hours. Therefore, if you have left the watch un-touch for a few hours, chances is that it will stop. It is recommended to wear the automatic watch daily in order keep the mainspring moving and your watch ticking everyday.

I hope this is helpful to you.

Q:

A: I think you need to take it to a jewellers and they will send it back to Seiko to get it sorted. Had a similar problem with mine and that's what they did.
