Seiko G757 weak alarm

Post30 Jan 2013, 16:14

Hi,

I am looking for advice on how to troubleshoot and repair the alarm on my G757. The sound element came loose in the case and it seems to only produce a very faint sound. While active, it also appears that the alarm is drawing too much current which causes the display to fade.

Is there a good guide/thread somewhere on how to approach the repair of the alarm for these kinds of watches?

I have searched the archives and didn't find much though that may be to my poor search skills.

Thanks in advance.

Hi,

My son has been wearing this and I finally got a chance to check it out. It seems that whenever the alarm fires, the display dims as if there is a voltage drop. A fresh battery lasted 2 months in it when my son brought it back to me. I checked the voltage at the spring contact and I'm not really seeing any. The manual says to check resistance at the coil which I am reluctant to do as I have to disassemble the movement to get at it.

The piezo element has come unglued and doesn't look to be in great shape. There seems to be a small shiny spot on the movement side which may have aligned with the spring, but it is hard to tell.

So I am looking for advice on what steps/tests I can take before I start taking the movement apart.

Also, does anyone know if a replacement piezo element is available?

Thanks

Mike
