  1. A data point: the 7-8 secs fast has come down to 4-5 secs. Is that normal?
  2. 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.
  3. It is not causing me any stress; thank you for the patronising answer. I asked a reasonable technical question.
  4. 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.
  5. 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!
  6. 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 ;)
  7. They go on Ebay for 5-6k and that is in unknown condition and no warranty
  8. The watch has come back from IWC. Looks perfect. I am a bit nervous about the ceramic however *edited*
  9. 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.
  10. 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 case" attitude doesn't help... it is really good for revenue generation though! I also wondered if it would help, if using a flexible strap e.g. fabric or silicone rubber, to somehow insert a metal link next to the watch and have the strap attach to that. That will prevent the pin getting flexed. Has anyone in the business here come across any of this before? Or maybe my watch had been attacked by a monkey?
  11. 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 isolate the customers from the internals. I never ever got through to anybody who knew anything about watches. Yes swapping the case is the only obvious explanation, but who would do that, and why? IWC must have good security, which (based on some other businesses I know, where customers routinely haggle about what they sent in and in what condition) very likely involves a video of the person opening and closing each package.
  12. 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.
  13. I am paying the 2.2k. The Ebay option would be doing a dirty on somebody, notwithstanding the fact that "half" the sellers on Ebay do that already But I want to get hold of the "correct" pins, whatever that means. Regards ceramic cases, they don't scratch so look like new for many years, whereas metal cases look quite naff quite soon. But obviously ceramic lugs are a weak point. There are many pics online of IWC lugs having broken right off. I am also surprised by the IWC report of a badly damaged gear train. How much of a shock would it take to do that, while ending up with a watch which is still accurate to better than a second a day afterwards - as this one was, all the time it wasn't gaining 3 seconds per minute? I am disappointed with IWC communications. The people you speak to know almost nothing about watches and are clearly under instruction to say as little as possible, while the people who actually do the work are absolutely banned from any contact with customers. So you just get bland descriptions and no way to get to the bottom of anything. But hey this is the way of most organisations these days... Those which aren't full of idiots keep the smart people well behind the customer interface.
  14. I wonder if there is a specific vulnerability here, in the spring pins naturally flexing (as the strap gets pulled, with normal arm movement) and exerting possibly large forces against the sides of the holes in the ceramic. Such forces would place the ceramin under tension, and we all know it is very weak in that mode. Are there special pins for these watches? I have been using just normal pins. I use a silicone rubber strap (ex Traser watch) because I swim every day and a leather one gets smelly I don't like metal ones due to hair pulling. I also wonder about that oval shaped depression. It could not have been created just with a knock, because this material is really hard. It would have just smashed. It looks like a manufacturing defect. But it isn't visible in my original post-purchase pics e.g. The only possible explanation (case has been swapped) is pretty serious and not one made lightly.
