The Breitling Watch Source Forums

last changed the date when the clocks went back 31st october so a good month ago, wear the watch every day and have not wound it in this period, and when i changed the date today I checked the time on time.gov and its exactly correct so 0 seconds loss in a month, cant complain really.

and i still love the watch, even if it has picked up the odd scratch

Yeah my silver dial is holding at +/- 0 sec/day. But # 2 is now the $600 Boschett Cave Dweller! Haha.

My black Steelfish (daily worn) hovers right around 1-2 seconds per day slow. So close that I rarely think about resetting it!

That's within COSC specs for a chronometer. The reality is any Breitling or stock ETA or Valjoux movement can be dialed in to near zero sec/day off. For a while anyway. But for an automatic movement -4 to +6 seconds a day is what a certified chronometer will do. My $2k Steelfish is keeping better time than my $10k IWC 7 Day or my OTHER Steelfish. Just serendipity within the acceptable range.

One of the inherent problems with long power reserve watches is that it's harder to maintain consistent accuracy.

Thanks -didn't know that. In a general way, why is that so?

The Coles Notes version.....

Accuracy relies (in part) on consistent tension through the running train, and that tension is provided by the mainspring. When you have a longer mainspring (longer power reserve) or multiple mainsprings then it is harder to maintain that consistent tension.

i didn't know that!

one other question: if a watch is full charge tends to be faster than when the power is low?

No.

It runs faster at both extremes, but for different reasons. Not going to hijack this thread further with a long detailed explanation, we can take it to a new one if needed.
