A friend has just messaged me, she thinks she has busted the Seiko m726 dive watch.
She got the battery replaced yesterday and was pressing the buttons and going through the functions and it has been stuck in dive mode for the last 12 hrs.
The buttons sound like they aren't depressed.
Is this a common problem and is there any solutions I can give her to get it working again.

Did she open it and replace the battery or have someone else do it?
If it is being used as a dive watch I would recommend new gaskets.
Without an open back movement shot it would be hard to see if the pushers were obstructed in any way from making contact like apinched gasket.
I'm sure an M726 expert will chime in with the correct movement reset practice if there is one.

Thanks. She had someone else fit the battery for her. Pretty sure it was a jeweler. She may be better off taking it back to them as they commented on it's good internal condition.

Hi Cam. There are both a user manual and technical manual for the m726 over on SCWF. The tech manual mentions two things that may be relevant - you have to press a reset button on the movement after installing a new battery, and there is a dive sensor. I assume maybe the dive sensor activates when water or pressure is sensed. Does it put the watch into dive mode? If so, perhaps this sensor was displaced by the jeweller? www.thewatchsite.com/files/Seiko%20Technical%20Manuals/M726A.pdf |

Did it happen right after the battery or just out of nowhere?
You'd hope they checked for normal operation after the battery change. Also you may need to reset the movement.
The buttons on the circuit board of these usually work by having two tangs bridging when the pusher is pressed on them. So being stuck in a mode usually means there's crap in the tangs or the pusher/pusher spring has gone awry somehow. Either through gaskets or mechanically.
I don't think this would be a membrane style button....SEIKO's membrane buttons from the 80's are AWFUL. Ask me how I know. But they are very prone to "mode sticking"

Thanks. I will let her know. I think back to the jeweler is the best bet. I'd be hesitant to tell her to send it to me as I would really struggle to send it back.

On many Seiko digital and ana/digi movements, pressing and holding all the buttons for a few seconds will perform an "all reset" on the movement's IC.
Might be something to try.
