Automatic Watch Second Hand Stopped Moving

[Henry066]

Hello,

I have a Seiko Presage Automatic Watch, model number 8R48-00J0. The seconds hand stopped moving, along with the minute and hour hands. However, the small seconds hand is still moving. I tried moving the watch around to wind it to no avail. I am a complete beginner to watches. Any help would be greatly appreciated!

by beginner is this the first watch you going to try to service? In other words you have zero other experience?

then one of the problems with the group is too many categories some of us like me go to the unread tablet basically and go through the unread messages are there is probably look at specific discussions that means it discussions like this in the wrong category may conceivably never be seen by theory the moderator or Mark should come along and move it to an appropriate location where it will be noticed.

also be nice to post a picture as most people probably won't know what this watches. Also the background history newly purchased you've had it for a number of years background history's help for problem solving.

I'm attaching the tech sheets it looks like you can wind this watch up by turning the crown. then because I can see the tech sheet it appears to be a chronograph and as nice as the manual is this isn't really a newbie's watch to work on at all. That is unless of course it's a practice watching a don't care if it never runs again. I would find something simpler to start with but in case you want to get started here's the manual

 This indicates its still ticking?  can you hear it ticking?   which indicates  the fork is kicking thus its running away, perhaps from you for  fear of getting ruinned  ,    guess by who.

What you have there is a chronograph. The large centre-seconds hand is the chronograph seconds hand, and it only starts moving if you press the top button. Stop it with the same button. Reset with the bottom one. If the small-seconds hand is moving, then the watch is running. What makes you sure that the minute- and hour-hands are not moving?

Hello. Thank you all for the response. M. Klassiker solved the problem by telling me to press the top button...Thanks a lot. I'm an idiot!

Not at all, but you do have a lot to learn about watches! Stick around here. You will learn a lot in no time. Congratulations on owning a beautiful watch.

no not an idiot you made the classic mistake of thinking you shouldn't read the users manual.  after all it's only a watch why should you read the manual so in case you through the manual way they didn't want to read I've attached the PDF. Then I found a couple links describing your movement
