I have seen the the new movement has a power reserve of 70 hours , can any one tell me is it more accurate then the old models ? and will it make the cross over to other models such as the blackbird anytime soon ? I dont want to buy a black bird and then find a better movement available six months later! is the current black bird a uni-directional rotor ? any info appreciated

It is Chronometer rated (just like the current movements) so that's -4/+6 seconds a day. I, for one, am hoping LIKE YOU WOULDN'T BELIEVE that the B01 makes it's way into a few more models soon! God knows when that will be though.......... and with Breitling's recent design and marketing decisions, your guess is as good as mine. Not sure what you mean by a uni-directional rotor. All automatic watches have bi-directional rotors (i.e. they move in both directions) but some only actually wind the watch in one direction - either clockwise or anticlockwise. In a movement like that it essentially just "free-wheels" in the other direction. However the current Blackbird movement (the B44) winds in both directions. |

I pretty much typed all that, but Driver8 beat me to it in posting  With the supply of ETA ebauches drying up in hte next 18 months or so the assumption has to be made that in house movements will find their way into more models sooner rather than later - whether it be some variant of the B01 or a different movement entirely. |

Thanks driver8, you answered most of my questions. why does the B01 have such a larger power reserve ? I (for one) do not like the look of the new chronomat ,its proportions just dont look right , its face looks small compared to the old chronomat , ( probably something to do with the broad flat bezel ) |

From a technical standpoint it's a combination of the size of the mainspring combined with the use of low resistance design, construction and materials (to minimise wasted energy). From a function standpoint the larger power reserve is a good thing for people who don't wear their watches all the time and 70 hours theoretically provides enough reserve for someone who only wears their watch Monday - Friday, although they are still a long way short of exceptional with 70 hours. |

technical answer is preferred ! would a lower resistence design with less wasted energy not automatically make the watch more efficient and less likely to lose time? ( i realise other factors will also come in to play here ) as a matter of interest if 70 hours isnt exceptional with a COSC watch , what is ?

I'm with RJ cubed on the 'exceptional' - 31 day power reserve beats PAM  To be fair it's not always like for like comparisons because you have to consider number of mainsprings and whether serial or parallel as well as the number and type of complications - but this is rapidly becoming another watchmaking article - I'll add it to the list. The friction reduction doesn't really help with accuracy as that's regulated by the escapement, what matters more with accuracy is the ability to deliver consistent torque through the running train to the escapement regardless of the amount of reserve left in the mainspring. |

No, the power reserve of the Lange 31 is exceptional OK, yeah I forgot about that one!  But my excuse is that is so far out of the realms of affordability, it just passed me by!

I look forward to reading the article Roff, sounds very interesting, if I can be so bold
