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

Thanks for the info John, I suspected it would need new seals and have not tried to use to much force trying to loosen the crown. I have not taken the back off and hope the batteries have not leaked

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.

      Parts sourcing for FHF 180 movement

      By JohnR725 · Posted

      I am puzzled by something a snipped out something from your image and what exactly disassemble tell us? my confusion is the symbol for FHF looks like image I have below year symbol as a star and righted this instant are not finding what that means? I suppose we could use the fingerprint system to verify it really is what it claimed to be. Size itself is really interesting there's almost no watches in that particular size. Then were missing details in the photograph above like diameter of movements to verify it really is the size and are missing the setting components.   went to the bestfit book looking at the symbols didn't see it. Look at the link below I did find it back to the bestfit book and yes it really is there https://reference.grail-watch.com/documents/history-of-ebauches-sa/ then bestfit book says lists the size as 10 1/2. one of the problems with vintage watches is finding parts yes a donor watch would be good.

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      Actually, this could be the issue. Drag from the module could be overcoming the cannon pinion. It was definitely not at the point that the driving wheel was loose on the cannon pinion, it took a little bit of effort to rotate it when applying the grease. Maybe I need to look again at applying oil to the pivots.    Yeah, it's very annoying. I don't want to give up on it, so back on with it over again until I catch a break.

      The sping is not pushing directly on the cap, but is pushing against the spindle. So, even if the usual black cap is replaced with the micrometer cap, the spindle is still pushed up.

      But he tells that the micrometer cap doesn't screw into the spindle. How can the spring push the spindle up if there's nothing to grip? There is a screw visible on top of the micrometer cap so should it be able to screw into the spindle? I'm feeling really dumb now. Does anyone manufacture that cap as an aftermarket item? Might be worth investing. Ok so the spindle is different, now I get it.

      I suppose? If it worked before and it doesn't work now I guess the question would be why does it not work now? That would come back to if you did not have the chronograph module on will it work or is the chronograph module sucking too much power out of the watch basically 99 usually when they go bad you can hold on the tube part and usually just spin the wheel because it has zero holding at all so usually when they go bad they go bad very bad. You should build hotel when you set the watch as to whether it seems to have any friction or not. I'm just wondering if the chronograph module is the problem.
