• So, I got the watch (BB58) back from warranty repair Monday and I don’t think it’s right. Winding feels smooth at first, but then there’s a significant resistance not many winds in. The blue version I had, even when it was fully wound it would just make a little, gentle “click” (clutch mechanism I assume) when fully wound. However, it was still super smooth with no resistance. This one feels completely different. It’s also running at around +7s per day and COSC should be between -2/+4.
    So, what would you do? Am I too picky? I’m thinking just enjoy it and see what happens but then again I have that thought at the back of my head, that somethings wrong and I can’t fully enjoy it. It’s just not ideal having bought the watch 2 months ago, and worn it it for maybe 1h total.
    Sorry about the rant, but there it is...

  • It’s also running at around +7s per day and COSC should be between -2/+4.

    Not sure where the -2/+4 is from but these are the figures for COSC chrono certification

    The final test figure is taken as an average of 5 different positions (with a max variance of 5 or 7 seconds between positions) at three different temperatures IIRC.

  • I think this (-2/+6) is for the older in house movement, the new, smaller one for BB58 is supposed to be -2/+4. I’ve read it somewhere where they compared it to Rolex which is -2/+2 saying that every guaranteed second means a lot more investment.
