Many thanks (and some details, en passant...)
The worst offender is a Sinn 244 Ti. The watch is ~6 month old and touted to be extremely resistant to magnetic fields (inner case of soft iron) up to 80,000 A/m.
The movement is an ETA 2892-A2 (nothing to write home about).
Now (and this is a reply to MTF) this is more or less the league I'm playing in - my most expensive watches are a GP9000 chronograph (purchased pre-owned in 1995) and an Omega DeVille Coaxial Escapement in RG (first coax launched, "limited edition" - mine is 995/999). So, I hope you understand why I was somewhat reluctant to register on a forum where I read that the finish on some five-digits (USD) PP movement is "average".

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...
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 chronome...
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...
