leighb Wrote:Hello All,I'm recently the owner of a Big Ingenieur (IW500501) and, whilst I love the look of the watch and the obvious quality of craftsmanship that has gone into making it, I can't find anywhere any documented specifications (online nor printed in the box) regarding the guaranteed accuracy of the watch. That is, at what level of error in accuracy does IWC consider the movement to be "defective", or that the watch is not "fit for purpose".I don't wish to start a fresh debate around accuracy versus function vs craftsmanship. Suffice to say that I'm of the camp that believes when I lay down $10k+ on a watch I expect it to perform to at least COSC specifications, if not substantially better. It is a watch afterall!My reason for asking now is pure curiosity. I haven't measured the accuracy in any scientific way as yet, but it seems to keep good time, albeit a little fast (typical of my other two mechanical watches also, one of which needed a warranty service for being way too fast). I'm just a detail freak.I guess I'm preempting any problems that may arise with accuracy, and would like to know what IWC's official stance or specifications are on this matter.Thanks for any help.

donald wilson Wrote:Rest assured: IWC guarantees that its watches will not lose time and will not gain any more than 7 seconds per day. That means a -0 to +7 second variation daily from a perfect rate. Thus IWC sets a stricter standard for accuracy than does COSC, which sets a -4 to +6 second tolarance daily.
Time is something invented by the Swiss to help sell more watches

Michael Friedberg Wrote:On COSC specifications, Donald is right. However, on the issue of "published" specrficiations, please note that the two big users of COSC are Rolex and Breitling. Brands that don't do that (with a few exceptions) are Patek, Vacheron, Audemars, Breguet, JLC, and virtually all high-end brands. Also all of the high-end artisan watch companies --Journe, Parmigiani, and even Gruebel Forsey (which starts at over $250,000) don't publish specifications or claim COSC standards.I know a lot of consumers think that Rolex and Breitling are expensive watches, and it absolute dollars a watch that costs $5000 or $7000 is a lot of money, But in relative terms these are at the low-end of the fine watch market --the other brands have a pricepoint thaty on average is probably 3 to 10 times higher. The question, then, is why do the more expensive Swiss watches uniformly not publish specifications but the lower priced ones do? I submit it's a marketing thing --Rolex is more of an "entry level" fine watch for many consumers, and they need some assurance that it's a quality product. A buyer of Patek or Breguet, to pick two examples, is looking for something different, even though he expects his watch to keep good time. I've written on this before, and there's more in archived posts.

Ben Dinnerville Wrote:Does anyone know if this applies to all watches sold by IWC or only those with in-house movements? The reason that I ask is that both of my watches with in-house movements (Mark XI, 5001) run to this benchmark, but my 3799 runs at -4 (well it did, not sure where it is at now since I got it back from a quick service).Ben
