New TT Sub Losing Time

[MX2000]

I purchased my first Rolex, a 116613LN this past February and couldn't be happier. I decided to wear a different watch this weekend, so I gave my sub a full wind (40) and placed it in the safe Friday evening. I got it out today after about 32 hours and it had lost almost 2 hours in timekeeping. Is this normal? I thought it had a 48 power reserve. Would appreciate any and all feedback.

Thanks!

Anyone?

Are you sure it was completely wound up?

[MX2000]

Yes. I carefully counted 40 and ensured they were full winds. This is the first time I have not worn it and it has kept great time for 6 months of ownership.

Congrats on the TT Sub. I have the same model and I've found that around 80 winds of the crown will completely wind it up.

40 isn't enough to fully wind. It's enough to get the watch going but not enough to get the full 48 hours out of the watch.

Hope this little bit of info helps.

Enjoy the watch!!!

Thanks AK-Rolestar! I will give it a try! Would hate to need to send it in so soon! I absolutely love the TT sub! Next purchase will probably be the bluesy!

I own the exact same watch, I would not worry too much either, it is very possible the 40 winds were not enough as mentioned, I know what the power reserve is suppose to be but I never really pay that much attention to it as I rotate my pieces and all of them run out of reserve at that stage.

Would wind and repeat, should be fine!

Thanks guys! Will do...

Make sure you do the math properly too. Friday "evening" - 32 hours later is like Sunday at about 2 am..

Have fun testing.. Full wind, log time, let set until it runs down, check time it stopped, do math.

[Foxglove]

sounds like simply stopped / close to stopping and lost time because of that. Was it running when you took it out?

I would suggest re-doing the test under more controlled circumstances.

Yeah good luck and keep us updated please.

[Chadridv]

Question too. When we talk about 40 winds, are we talking forty 360 degree crown rotations or just 40 pushes of the thumb forward until comfortable and then repeating?

Sorry if I'm not explaining that well, just let me know if you don't smell what I'm stepping in.

[Andad]

40 x full 360 degree rotations of the crown + another dozen for good measure should do it.

You should be able to feel the mainspring slipping when fully wound.

[MX2000]

80 full winds and 25 hours later and all is well! Will check in the morning at approximately 32 hours. So far so good!

[AK-Rolestar]

Sweet!

I've also noticed if you store the watch crown down on its side, it will keep more accurate time.

Something else to think about testing if you'd like!

Keeping the crown side down will not necessarily keep more accurate time unless you have a watch that's running fast (I believe). Either way, each resting position will affect the movement differently and you can self regulate your watch by putting you watch in the appropriate position overnight depending on if your watch is fast or slow.

t well, just let me know if you don't smell what I'm stepping in.

Full 360 degree crown turns clockwise only, all mechanical watches only wind on the forward turn.
