SD43 Accuracy

[Tombros]

Hi guys, I have read in a old thread that the SD43 is really accurate in terms of time keeping. People say its right on the dot for monthes.

Mine is -4s a day... is this an issue I should worry about?

Sorry this is my first Rolex so kind of worried.

Thanks in advance!

Rolex certifies +2/-2 in their new watches so you might swing by an RSC to have yours regulated.

Accuracy comes down to regulation. New movements aren't any more accurate than the old ones. My 14060M currently runs +1 second per week and it's 8-9 years old.

Not worth worrying about IMO but not within specs either. If it’s new though I’d give it a bit of time to see if it settles down.

[strafer_kid]

Through the years I have tended not to get too uptight about precision accuracy with Rolex. That said, my SD43 does appear to be very good in that regard.

Some have reported 3235 is less stable/accurate than 3135. There was a discussion thread on this issue on a Chinese watch forum. Definitely something you should keep an eye on.

Your AD should be able to help you if you want to correct it. Since you are in Vancouver, AD will have to ship it to Toronto for warranty service.

Wouldn't be a problem to me, wear and enjoy. Check it again after a few months.

[Uncle00Jesse]

Mine is about 2.2 spd slow. Used to bother me when I hear people say theirs has been spot on for months but I got over it. Enjoy your watch it’s not a big deal. Mention it at service time but even then they will re-regulate

[samson66]

Give it some time. Mine is at -1.7 s/day one year in. It may settle

How do people test this? I have no idea how to tell if a watch is running fast or slow a few seconds a day.

Wear it for a few weeks continuously then check the timing.....mine took a couple of weeks to settle now it is -0.5s during the day but I can gain that back at night leaving it face up, if it's crown up or down at night it will loose another 0.5s.
It's a phenomenal piece and super accurate

You simply set your watch to an atomic clock....either on line or I use a Casio G-shock which is reset every day automatically so is accurate in Europe anyway...then check it the following day with the same clock. Simples

Movement sometimes takes time to settle in.

I would let it be for now. Wait six months and see if it improves or worsens.

Fwiw my sd43 has been spot on.

+1

I got a different problem. Mine is dead accurate but the amplitude is very low for a brand new watch. I have it for a year now but it has been worn sparingly and my amplitude is 262 face up and 259 face down. All my newer (less than 5 years old ) 3135 are running over 300 or very close just under 300 ! I don't know how normal this is. I was about to open a new post when i saw yours.

Nothing to worry about. It varies with all positions. You can’t expect a mechanical watch to be as accurate as an Apple Watch.

[Tombros]

Been wearing mine for about 1 month.
Sorry I am new but how does the positioning affect the accuracy? Is there a way I should put it?

[Tombros]

Thanks for the tips guys, i will check again in a couple of months to see if it settles.

[Air Rescue 5]

I promise you this, the SD43 is not “right on the dot for months”. But as stated above, +2/-2. If it’s -4, then you didn’t get what was promised to you. I would send it in for a warranty check up. But some people are happy paying for something and getting short changed. As stated , waiting 6 months is sound advice.

[dberdichevsky]

I just got my brand new SD43 yesterday. It came right out of the coffin and onto my wrist. In the 24 hours or so that I’ve had it (about 9 hours off of my wrist sitting on my nightstand last night) it is about -1 second. I hope this helps, but most other Rolex’s that I’ve had do take a few weeks to settle into their normal rhythm.

As a first time owner, one more question sorry, Google is saying that you should not be able to hear the mechanics running from the watch but I could when i hold it against my ears. XD Am i supposed to hear the sound?

I never heard the mechanics of my 2 month old Submariner until I read your post and held it up to my ear. Yes, I can hear the mechanics clicking away. Sounds pretty cool actually.

Yes, this is normal. You should be able to hear a faint precise ticking from your mechanical watch. Google doesn’t wear a Rolex and may not be as lucky as you to know the answer to this

I don't think that would work on a modern Rolex.

[mr_gray]

to the OP -4 seconds per day is i think COSC but not METAS compliant. rolex will address this if you take it back (i am sure this is already stated of course).

for me -4 seconds per day is unacceptable. firstly i want a positive number (much easier to adjust periodically. just hack for an interval and release, no hand adjustment required (the minute hand must of course be perfectly aligned with markers)). second i want a number smaller than 2 (2 will do of course).

negative discrepancies i would be less tolerant re: magnitude (as indeed COSC are).

I use AtomicClock app on my iPhone.

My SD43 was way off (fast) initially, but ended up going to absolutely dead accurate through use and giving it a wind every other day or so even I woke up.

My DSSD (also 3235) runs around a second a day fast.

The 3235 uses ball bearings in the monobloc-shaped rotor on the self-winding module to increase the speed to more rapidly wind the longer, high-capacity mainspring.

The 3135 uses a low-friction synthetic ruby at the axle of the rotor, which is much quieter. The ball bearings do make the 3235 more audible, not the ticking, but the whoosh of the swirling rotor (method by which the watch is automatic).

How old is it?
Wait a year and if it hasn't settled down then perhaps it may need a little adjustment.

The main thing is that it's consistent.

[Seibei]

I would find -4 annoying but tolerable.

[CAN_VAN7]

I have had an SD43 for over a year and it has been running -6 to -9 the whole time - finally gave to AD to be fixed the other day. Hopefully this fixes the issues... I recommend getting it fixed if over -2 a day.

[Chalet]

Mine was awful. Losing 4+ seconds a day. Took it in to RSC. Went for a coffee, picked it up 30 minutes later and it’s now +/- 1 per day.
