Calibre 4302 issue
So the calibre 4302 has a 70h power reserve, which is great. However, I tested it three times and it these were the results:
Monday 9.11pm - Wednesday 5.35am Friday 9pm - Sunday 2pm Monday 9am - Wednesday 11am Far from the 70h power reserve... I'm meeting AP's watchmaker next week Friday. Anyone else here who had a similar issue with the calibre 4302? Yes, I watch was fully wound. |

I'm wondering, how to tell if fully wound? Is there guidance someplace (perhaps I should have read the manual)?

How many turns is a full wound? I have recently bought Code 11 with 4302 and will try it.
Checked the manual, but there is no info. Except that it should start running after 25 turns. Rolex for example is 70-75 turns for full wound. |

There is no info in the manual. I did around 40 - 50 turns. Rolex is definitely not 70. My 2016 Sub needs 40 turns for 48h power reserve.
Will update this topic once I've spoken with AP's watchmaker next week... |

I also wounded my Code. Let's see how long it will last. |

There are a lot of wild guesses and wrong opinions around ... I MEASURED it for 4 different Rolex watches using a professional timegrapher. After 40 full turns the tested watches all reached a maximum in the achievable caliber amplitudes, which means that they are fully wound. Look at my two graphs in the above linked post. |

You are not winding it enough my friend. Do 80 then run your test and have fun

Alright, my code stopped about 525pm. That's slightly above 70 hrs. As some of the other guys said, you might not have wound it fully. It takes my fingers 2-2.5 twists to actually turn the crown a single complete round. Perhaps you could try winding your watches at least "80 rounds".

Thanks Zavier. I'll wind my Code 11.50 a bit more. After 50 turns, I do get some resistance from the crown, don't want to damage it. Nevertheless, going to AP House on Friday...

It is safe to wind an automatic watch as many times as you like, they have a slipper clutch whichs stops the transmission once the max power reserve has been attained.

40 turns, both lasted 65 hours with a couple of minutes apart. Both were in the case, dial up. Maybe I need to make sure that I do full turns. My Code on the other side did 53 hours but I did around 50 turns. So I will repeat again in the coming days. |

If you have a timegrapher you can do the same measurement for your AP Code11. |

Thanks for all the replies and knowledge. Something is clearly off with my Code. Did around 50-60 turns on Sunday 10pm, it stopped today Tuesday, 3.10am.

Calibre 4302 issue
I have a new 15500 RO and I’m experiencing similar problem. Furthermore, when I wind the watch from scratch, it doesn’t start until after I wind it for like 70 times and I turn it physically around and back up.. while when I wind a 15451ST we have at home and it starts running I wind it

I initiated the test again. 2 GMTs 126710 and I made sure I do 40 full turns, resting position dial up. I also wounded up my 114060 40 times to see if it will do the 48 hours. Same with the Code, but this time I did 80 turns. I also want to double check the accuracy. In the first run the GMTs were +1; +3, while the AP was +11 Will update the thread on Friday. |

Normal - happens on my CODE time only (same movement) and my ROO 43. It has to do the with new movement 4302/4401 - it just takes more winds to get it going and I think it has to do with the barrel size and how the movement is constructed. The old 3120/3132/3126 use the 3120 as the base and will start itself with 1-2 winds or even just moving it around for a couple seconds. I can’t speak for other brands but it’s the ‘sacrifice’ for a larger barrel and longer power reserve |

Thanks for letting me know. I was feeling kinda weird about maybe having a problem with my piece. Good to know it’s just the new movement’s barrel and power reserve (: Sent from my iPhone using Tapatalk |

Just came back from AP House. They did a few tests (forgot the exact name), and everything seems fine. You do have to wind this calibre at least 80 turns. Will test it one more time over the weekend.
Not related to the movement, but the watchmaker did say that dust can get into the CODE easier than other watches... Dust underneath the sapphire crystal... In case that happens AP will clean it. |

I wound mine around 100 times on Tuesday at 10:30 am and set it face up in a watch box. It quit today (Friday) at 1:50 pm. It was a tremendous sacrifice to not wear this watch for 3 days, but in the name of science it had to be done.

I did another test. I made sure I wound the Code 80 times. It did 76h 4min. So it does indeed need more wounding.
Accuracy though was at some point +20sec and then it wend down to +15sec. I was expecting to be more accurate. How is other's Code accuracy with 4302 movement? I also tested my two GMTs, each one with 40 wounds. BLRO 72h 47min BLNR 74h 38min |

I just had a similar issue with my 4302 in the 15500. I had worn it for almost a week (maybe one day off the wrist during the period) and it stopped after about 24 hours. Possible I just was being sedentary throughout. I gave it around 70 winds now so lets see how this goes..

Glad I came across this thread lol. I was a little worried that my 15550 took longer than “normal” to get the movement wound up, especially because my 15450’s movement winds right away |
