About 126600 SD43 running slow

[cherrie.n]

HI, all guys! Thanks in advance!

My new sd43 126600 running slow about -2sec per/day.

I hate slow watch...

how about everyone 3235 Movement running situation? slow or fast?

Thanks all again!

[zaclee]

mine runs 10 sec faster than my laptop's clock -.-

and how would you fix it or just let it be?

one day +10sec?

[Net-man]

Same here SD43 runs consistently slow 2~3sec/day
I leave it crown up when I take it off.
Maybe due to resting position for 10-12 hrs, don’t know.
People would say within specs.

Mine is about 3-4 seconds slow a week. I only wear it about 3x a week and rest it dial up.
If i put it on my cheap Amazon winder, it loses a second every 24hrs.

Mine started off to the races all motivated at about 2 secs fast every two days...now it's like, dude the honeymoon is over, love me for me, and it's running exacty on time for a week now. Hope it doesn't start "slowing" further. But before I get too bothered I need to troubleshoot and confirm my timing sources.

Just under 0.5 seconds fast per day. I picked mine up end of May this year.

[VicLeChic]

Mine was -0.5 s/d last time I checked.

[rudestew]

Got mine back ( -7 a day ) and now +2 over 8 days

my new explorer 1 MK2 ran 1 sec fast per day first 2 days, now 1/2 sec + per day (if that), rest crown UP at night if i notice a bit fast, this brings her back to even. CROWN UP for me to lose a bit of time. i suggest experimenting with resting positions to even things up some. i am VERY happy with her accuracy.

[N5XTC]

but yes, SLOW watches bug me, harder to set back to exact time. fast is easier, pop the crown.

[Onequik135i]

My Sub always ran a bit slow since day of purchase, last I checked and always reads the same just about -3/-4 when timing it against Watch Tracker App. And my earlier 5 digit GMT II runs on the quicker side +5/+6.

[N5XTC]

being neurotic about watch accuracy sometimes helps. had a 1948 hamilton pocket watch that would stop a few secs and begin again every now and again. i would have never noticed had i not been neurotic about checking it. also, i like being neurotic and tracking watches, part of the hobby for me, not for everyone though. we all can't wear black and ride the same motorcycle!!!!

I track all my watches, part of the fun for me too.

sorry for the multiple posts, when i was looking at vintage watches at dealers, i would wear the watch, wind it 40+ times, set to the atomic clock and give it back. come in next day and check, without saying what i was doing. this way, i would notice if a watch was way off (many vintage are). i know it is in one position in the display case, but it still gives me an idea about accuracy.

RELATED QUESTION, maybe should be a new forum post, does anyone think having the watch under the lights in a display case all day every day hurts the watch (maybe dry the oils?), just was thinking about that.

[1William]

My SD43 runs about 1 second slow a day when I wear it for 24 hours. When it sits on the winder for multiple days I lose about 2-3 seconds a day. I am not looking for perfection just a steady performer.

[samson66]

Last time I checked mine for an extended period it averaged -1.1 sec/day which is just fine by me. I think it's pretty amazing actually. I think that's around 99.999% accuracy if my math is good. Lose one second out of 86,400 is pretty impressive for a purely mechanical device.

[brandrea]

Welcome to the forum. You’re within spec so I’d be pleased with that

You guys worrying over a few seconds much more important things in life to worry about.Gravity affects mechanical watches the most that's why they are tested in 5 different positions.And in those different positions there will be slight deviations in the timekeeping.Remember this the escapement of a mechanical watch in 24 hours pushes the gears 432,000 times day and a day has 86,400 seconds consistency is the most important.Now mechanical watch on the wrist has quite a hard life given the fact that the movement is constantly affected by the earth's gravity, metal expansion and contraction, temperature variations, subtle changes in lubrication,mainspring-power-reserve and friction, shocks, and so on.The fact is that no mechanical watch made will keep perfect time, very close yes but perfect no.You could have two identical watches each timed on a machine to say +2 seconds,on one person's wrist it could balance out. But on another person's wrist with different wearing habits results might differ its because its mechanical.Have you ever given your watch a full manual wind say 40 full crown turn clockwise only.?Because when wearing with low activity you are not winding your watch enough that could have a effect on over all timekeeping its all down to peak power-reserve. So what this boils down too with the OP watch when wearing for 30 days the watch will be a whole minute slow WOW.

On a machine winder timing often differs from the wrist, on the machine movement in general is in the same position 24/7 normally just back and throe.The only thing needed with any Rolex watch to wind it most people have two they are called wrists and what the watch was designed for.

Mine's 1-2 sec slow a day. No Big Deal. within spec and i love it

No it's not a nice result many on forum states that Rolex regulates to -2+2 spec daily spec and should perform to that exact spec. And seeing that +2 seconds over 8 days then the movement is clearly out of Rolex spec.Or is only when say the watch is +3 seconds do many moan and fret but under Rolex advertised spec is fine.

[peterpl]

I've never had a Rolex that was fast. All mine have been slow although all within spec.

[SearChart]

-2 is within Rolex spec and well within COSC...

Good point Peter

Stew, your watch is too accurate Send it back

Man I consistently learn a ton of information from your posts!

We do try our best to give truthful and proper real information, but there are so many Rolex myths on the net, many believe the many Rolex myths and not the true facts.I am sure if Rolex advertised to get the best performance from there watches, you must hang upside down twice a day, with watch 3 feet of the ground many would do it.

[Mystro]

If your watch is running a bit slow, just hack the movement and set it 20 seconds fast and forget it. You will stay within that 30 seconds accuracy a month regardless.

[tmo8320]

Typically -1 to -1.4 seconds per day if I wear all the time. If I take off at night and rest it watch face up, I am more inclined to be dead accurate or perhaps +0.5. I’ve no complaints at all. This watch and the 3235 are absolute beasts. Very pleased.

Thanks buddy. When I see you have posted I try to take my time and read it. I learn something every time
