Horological Meandering

It's very valuable: it gives you a license to complain to the manufacturer.

 

In my experience, if you don't like the way your watch keeps time and complain to the manufacturer, you stand an excellent chance of being told that the watch is "within specification" and the manufacturer will not correct it. If your watch has a chronometer certificate and is not keeping time within chronometer standards, it is much harder for the manufacturer to take that approach.

You do have to have some sensitivity to condition. A watch that is keeping very poor time is probably damaged, magnetized or in need of service. (15 seconds/day fast is very poor time for a chronometer or high-end modern watch; for older or lower-end watches, it may be acceptable. If the timekeeping is consistent, it can be regulated easily.)

Maybe I'm just lucky, but the certified chronometers I have owned have all kept excellent time. Only occasionally do I get comparably good results from a non-certified watch, even if it is very high-end.

What is a chronometer certificate worth?

Hello to all PuristS, I have been reading this site for at least two years without registering. This is my first post because I really need your opinion on something I find rather strange. So, here it goes: I have a small collection of watches and that I ...

Welcome to the world of a poster rather than a lurker ! That wasn't so painful was it? Next, a slap on the wrist for taking 2 years to lose your posting virginity - is that a PuristS' record? That is why the more stringent tests at 'Qualite Fleurier' and ... 

A slap on the wrist? Well, maybe I deserve one...

...but you'll have to wait until I take off the mega-complicated extremely limited edition five-year waiting list watch that I'm just wearing (brand and model witheld for personal security reasons). You know those flying tourbillons are not as shock-proof...

Chronometer Certificates only assure consistency

Hi Just thought I will share with you some remarks on accuracy and consistency of watch performance ( I came across this in FPJourne catalog on the subjet of chronometry). Typically a chronometer certification certifies the deviation of the watch in vario... 

Looks like good news.

Since it means these watches are certified as being accurate and therefore can be set to run properly (within limits) using the rate regulation mechanisms found in all of them. Thanks

Hi Narsi, I'm a bit confused about some of the points in the info you quote. For example, I'm not at all sure that variations in gravity are a major, or even a minor, concern for wristwatches. Given that movements like the Lemania 5100 are known to be abl...
