Hi all , I’m looking for some advice on servicing my Heuer Diving Watch which I have had from new since 1984 but has been in its box for the last approx 30years. The model is 980.007 and it has never been serviced. The Battery needs replacement and I cannot seem to unscrew the crown. I have spoken to Heure who have said it will need to go back to Switzerland for a service as they say it is vintage. I live in North Wales and hoped somebody could recommend a good repair service more locally? Appreciate any help thanks Malcolm.

The problem with having a watch new in the box for 30 years is things still disintegrate. Like for instance the rubber seals found in the crown in the back community get really hard which would be good or the rubber can actually disintegrate and turn into a tar like substance.

I'm assuming from the pictures at the website below that your crown is probably a screwdown crown at the seals have disintegrated that may be why you can't unscrew the crown.

Then there's a problem of the two batteries been the watch for 30 years conceivably it's disintegrated and hopefully it hasn't leaked bad chemicals all over the place.

Fortunately a sizable percentage of the people this group are in the UK so maybe they'll recommend somebody. Otherwise simply go back in time and you knew your list or the watch for 30 years I would remove the battery and made sure the crown was unscrewed out so if the rubber does disintegrated it's easier to deal with the same with the back it would've been good just leave the back on loose

Hi  Information as supplied by John is indeed as always good. First get the back off because if the battety has leakes there may be ireperable damage caused to the movement. Any reputable watch repairer can do that. The seals are as John said going have to be changed as is the stem seal , getting that out will require a little inginuity as it is probably softened to the degree where it has now effectivly glued the crown in.  If you can remove the back a Picture or two of the movement would be appreciated.   cheers

Well, that's what they would say - they want your money.

As others have suggested, there are likely any number of local watch repair folks who can help you if you don't want to continue to explore servicing this watch on your own.

Even if the battery has leaked it shouldn't be too hard to replace the quartz module. As long as the dial and hands are fine then it won't be an expensive fix.

This model has the oversized 42mm case and is powered by an ESA (Pre-ETA) AS 536.121 movement.

Ebay are showing one new for 200 Betty notes

If you are lucky and you manage to get the stem out to release the movement. It may be fixable 👍 as 200 Betty's isn't cheap. Have it out mals and then lets have a look at its condition, there are a few of us on here that have some experience with cell watches.

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      So leave off the seconds. Stand the movement on its edge, its the dial edge that rests on the pad ( either rubber or cork , something that wont slip ). Use a finger of your left hand to hold the movement upright,  right hand presses the release and flicks out the stem. I do it this way so i can see what I'm under a microscope. But you could hold the movement between two fingers of your left hand, its the right that has to manipulate the stem out by pushing the release and flicking out the stem with  right ring finger nail. Sounds more complicated than it actually is. I guess you could fix a push pin to something solid, then all you need to do is push the release against the pin, leaving your right hand completely free to pull the stem out.

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.
