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

      I used to just remove the stem pop the movement in its case then put the stem back in check everything then back on the timer.

      That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean. Something like this, but tbh its better to just learn to do with your fingers.

      Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.

      That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something.

      I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
