How do you wind a Seiko watch? There are several types of Seiko mechanical watches which may need to be wound. There is the manual wind movement and the automatic movement. Both movements work in basically the same manner. They have a main spring which when wound powers the watch. Both modern manual winders and automatics have devices in their movements which prevent over winding. Old watches however do not and can be over wound. Over winding can result in the mainspring being broken. Care must be taken not to over wind such watches. When winding older watches it is a good idea to start out slowly. Find out how much each turn of the crown adds to the duration of the wind. This process takes some time, but when accomplished you can designate a time to wind the watch each day. This will help prevent over winding because you do not know how wound it is.
To wind the Seiko manual wind watch:
- Unscrew the crown on watches where the crown is screwed down, such as dive watches. To perform this, turn the crown in a counter-clockwise direction until it pops out slightly.
- Wind the watch by turning the crown in a clockwise direction until fully wound. As the crown is turned, you will feel an increasing resistance on the stem. This is the spring being wound tighter. The more tension you feel, the tighter the spring is getting. In time, with practice you will recognize how tight it is by feel. On older watches, counting the number of turns and stopping at a number which has proven to be safe is a good idea. It takes time, but finding that number a bit at a time is the best way.
- Screw down the crown on watches with screw down crowns. Press in on the crown gently and twist it in a clockwise direction. The crown should screw in smoothly with no resistance. If you feel resistance stop immediately and unscrew it again to start over because you could be cross threading the stem in the tube. If the tube is cross threaded and ruined it will have to be replaced to keep its water resistance.
To wind the Seiko automatic watch movement:
- Move wrist. The Seiko automatic movement winds itself with the movement of the users wrist while the watch is being worn. The automatic movement contains a half moon shaped part called a rotor which spins when the watch is moved. This spinning is the winding of the main spring. Some automatics may also be manually wound; if so, they may be wound in the manner described for manual winders.
- Place watch in watch winder. The automatic can also be wound by using the watch winder. A watch winder is a device which holds an automatic watch and turns it at regular intervals to keep the automatic wound when not on the wrist.
That is how to wind a Seiko watch.
Another good idea before winding older watches is to have them inspected and serviced at a local jewelry store or watch maker you trust. Upon inspection they can tell you the best winding process and how many turns are recommended for your particular Seiko watch.
