  1. I have just looked at the paperwork. They listed standard operations, plus some stuff which was clearly not relevant to the 3sec/minute time gain: replacement of middle case replacement of the second hand replacement of the second counter hand replacement of the hands replacement of the hour and minute hands The service was 416 and the "middle case" was 1433, inc VAT. Total 2200 inc VAT. I was not able to get any feedback on the cause of the 3 sec per minute gain, but it has not come back. It went back to IWC again a week or two later because it was gaining 8.5
  2. What a useless and presumptious reply. I documented an issue with a watch and you blame me for causing the problem. Admittedly I don't have your 8696 posts so can't be as clever!
  3. "So when you paid for the service and got the watch back you didn't get a receipt of what work was done?" From IWC, no. Their company policy is to disclose absolutely nothing. The receipt just says a service was done, plus the new case. They also get you to sign a contract before they do the work under which you agree to not ask for any parts they removed. I did try several times to find out what they found but they carefully avoided giving me any information. All kinds of fob-off stuff; it is clear their staff are under strict orders to not communicate with customers. What this
  4. Agreed, but then you basically learn two things - Swiss mechanical watches are a grossly overpriced "poser item" which has an annual "operating cost" averaging 250 quid a year, and that is the baseline for the simple chronometer types - any ceramic-case watch is best avoided because the tiniest thing can chip the material and then you get screwed over by the official service centre on the next service OR you change over to using "cheap" watchmakers many of whom don't know what they are doing, even with the common-as-muck 7750 movement which I suspect is not the point you were ho
  5. It's a lesson to anyone thinking about a watch with a ceramic case. It's a huge hostage to fortune, converting a routine 500 quid service into a ~2000 quid one
  6. Dropped it? Of course not! The 3 sec/minute fault could be rectified by tapping the watch with a knuckle of my finger. Interestingly, winding the watch up did not clear it. I could not get money back at any time. All the shop offered was paying for the "trade watchmaker" to have a go at it, which he did about 3 x, but after a year or so washed his hands of it, presumably because the shop refused to pay for any more goes. IWC did a standard ~500 quid service (as per policy, they never communicated any info whatsoever on what they did, which I find a bizzare way to treat customers, but
  7. I bought this one a few years ago and just noticed it is listed as new - 7.3k! Amusingly, this is what I paid for it originally (used; 3rd owner or so) plus the ripoff IWC service to fix this issue which got inflated by the cost of a new case which IWC insisted on before they would work on it... They replaced the 7750 movement with something called 69380 which is partly made in-house. Otherwise it looks identical. I wonder how common this is?
  8. On the original Q, if the motor is a brush motor then a normal lamp (light bulb) controller should work. Get one which can do a few hundred watts. If it is brushless, it will probably be a capacitor start motor (you can see a cylindrical component strapped to it) these cannot really be speed controlled. Well, it can be sort of made to work... The best thing is to get a small 3 phase motor and a speed controller known as a variable speed inverter. Control Techniques make them in loads of sizes, down to a couple of hundred quid, and the motors are on Ebay for probably less. You get beautifu
  9. I just randomly popped in a year later... Very interesting post by nevenbekriev above. Didn't see it last time. But also I don't know a watchmaker who would do such a job. I also see one of the mods removed my comment above that I would sell the watch Perhaps surprisingly it has been working for the past year, no problem. Worn 24/7/365, survived 2 ski trips, lots of off road biking. My guess is that IWC must have demagnetised the parts. They do claim to take the watch completely to bits and check each part. They never communicated in any way whatsoever regarding anything s
  10. Indeed; these fancy Swiss watches are basically junk. Good for sitting on a winder and you put them on according to the clothes you want to match
  11. Update: the watch ended up running 8 secs/day too fast so given that it had a 2 year warranty after that IWC repair, I sent it back to them. It came back a few weeks (!) later and it is now running 5 secs/day fast
  12. I was told, maybe wrongly, that the 7750 mechanism has separate adjustments for different orientations of the watch.
  13. A data point: the 7-8 secs fast has come down to 4-5 secs. Is that normal?
  14. Evidently they can be adjusted better, so why don't watchmakers do it? Does it take longer to do? My understanding is that these watches (ETA7750 etc) have several adjustments, for each of several orientations. But does it actually take longer? I have read from IWC that their company policy is to never have an IWC watch run slowly so if they allow 7 secs it means they adjust for 3.5 fast, plus or minus 3.5 seconds. Yet I had this watch adjusted for zero, plus or minus about 1 second.
  15. It is not causing me any stress; thank you for the patronising answer. I asked a reasonable technical question.
  16. I think the spec is 4 seconds a day. It is an IWC-modified ETA7750. Currently, fresh from an IWC full service, I am seeing 7-8 secs a day. The watch had been to another "trade" watchmaker previously (to unsuccessfully attempt to fix the 3 sec per minute intermittent fault which I posted here previously) and he got it within 1 second a day, so clearly this is possible. He said he was Omega authorised. And that was before IWC got it for their £500 service, prior to which they reported a list of faults e.g. wrong power delivery, wrong this and that, loose hands, you name it.
  17. Yes it looks just like new and I have a 2 year warranty on it. It will have to go back to IWC though because (on a better measurement) it gains about 8 seconds a day. The lesson is: never spend more than a couple of hundred quid on a watch!
  18. The funny thing is that the watch now gains about 3 seconds per day, after the £2200 IWC job, whereas the previous watchmaker was able to get it within 1 second, each time. Except when it was gaining 3 seconds per minute ;)
  19. They go on Ebay for 5-6k and that is in unknown condition and no warranty
  20. The watch has come back from IWC. Looks perfect. I am a bit nervous about the ceramic however *edited*
  21. I never abused the watch. Those chips in the ceramic are a mystery, but if they are the result of normal wear, that material is totally unsuitable for a watch. Maybe for posing The ETA 7750 movement on which this watch is based should be plenty robust enough, however.
  22. I have been looking at the strap attachment options and it sounds like with these ceramic watches the important thing is for the pins to be the most rigid type you can get. That also means choosing the length to be the maximum that will fit - to minimise the potential for the pin wobbling sideways. Also you need to make sure the diameter of the end portion is not a tight fit into the hole in the watch case. If it is a tight fit, it will create an enormous localised stress in the ceramic and chip a piece out of it. IWC's "we won't touch a watch which has any damage to the ca
  23. I don't think IWC ever understood the 3 sec per min issue was intermittent. Or maybe somebody deep in there did/does but the written response is illiterate. A year ago I sent them a movie proving it (posted in the other thread) because basically nobody believed it was possible, and after a lot of hassling their switchboard I sort of got a confirmation that somebody did watch it, but they were totally non committal as to the possible cause and how much it might be, worst-case. Very difficult, but not untypical for a present-day huge company (which I am sure they are NOT) set up to iso
  24. A very good point about a non-metal strap. That will try to bend the pins, whereas a metal (rigid) strap will just pull on them perpendicularly to their axis, which will greatly reduce the stress on the ceramic, around the pin holes. So I need to find a strap which has metal links at the watch end, and the rest is something which (a) doesn't pull hair out and (b) is ok with daily swimming. I wonder if there is such a thing. BTW does this forum software allow messages to be edited after saving? I see no button for it. Maybe it is disabled until you have reached some number of posts.
