The Breitling Watch Source Forums

Ultrasonics are used for cleaning watch parts, but even disassembled not every part goes in and I definitely wouldn't do it for the whole movement.

So I've spent a little more time with my B01 and do have an update regarding accuracy. From what I can gather, the watch is gaining about 2 seconds per day. Based on some research I've done, this seems to be reasonable, especially considering the watch has only been running consistently for about 3.5 weeks. If it doesn't decide to fix itself in another month or so, I'll probably take it back into my AD and have it regulated. Since there aren't many B01's in circulation, I just thought you guys might find this interesting.

2 sec a day is not 'reasonable', its extremely accurate, especially if it consistently runs at that rate.

A belated congratulations on your new B01 Craig. History in the making!

I actually had the pleasure of trying one on for the first time yesterday and I liked it. The dial looked good and it had good wrist presence. Now I'm not a big fan of the Bezel font but that's only my personal opinion.

The AD's informed me that it was accurate to 1sec/24 hours which if true is remarkable...I'd be very happy with 2 secs/day if I were you!

Not sure if I like it enough to purchase but definitely keen to see what other models it the B01 comes out in.

Well done and enjoy

That's sales speak. The watch can be regulated to that level of accuracy (and better), but there is no way that a 'traditional' movement can get to that level of accuracy in the real world as there are way too many factors at play - including all of the position changes. You would need to get to a vey fast beat movement (think Chopard's 10Hz) to be able to claim that level of accuracy.







And hopefully fairly soon!

I figured they were exaggerating that little bit of commentary. They've either been trained to use that gambit as a sales focus or they really believe what they're saying

One other thing they did say and which has been mentioned on the forum of course is that the Swatch Group are no longer providing movements as of next year, which means that the B01 is due to become the 'work-horse' movement for Breitling moving forward.

I know this came up recently, again if true, it might be a good thing for new models moving forward?

There is still considerable scepticism about whether Swatch group will follow through - and they will still supply movements, just not ebauches.

The B01 is definitely a response to that (in part), but the 7750 / 2892 et al are way out of copyright now anyway so no reason why they can't be developed by someone else (or in house).

2 secs a day is a brilliant result, especially under "real world" conditions.

When you bear in mind that the official COSC tolerance of -4/+6 secs actually represents 99.9977% accuracy, you can see that your +2 secs is pretty amazing.

I'm definitely not complaining about having a watch that's consistently +2 sec, especially right out of the box. I'd be interested to know what other B01 owners have noticed . . . although I know they're few and far between thus far.

I didn't realize there was a rumor about Swatch not providing movements to Breitling any longer. I'll be sure to keep an eye on this story.

It's not a rumour.

They announced it about 7 or 8 years ago and after a lot of legal actions it is now scheduled for 2010. What we don't yet know is whether Swatch will actually implement it then.

And just to be clear, it is not movements that they are stopping the supply of, it is ebauches. They will continue to sell assembled movements (but obviously not allowing them to be stripped down and modified.

hello,
I've been waiting a long time but sold my pam113 and bought new chronomat B01.
Craig, you were right - it is wonderful watch.
I think we don't have to worry about Breitling and Swatch group - Breitling has its own factory for movements assembly and as i know they build the own movements - they don't buy ETAs - they buy only patent - so even if eta stops selling it Breitling will continue to create its Calibers.
