Should I bother regulating my SD43 at the RSC Sydney AUS?

[Finfin]

My SD43 has been losing about 4 seconds per month since purchased 8 months ago. It hasn't changed in that time. This (consistent) loss of 4 sec per day does detract from my enjoyment of the SD43 somewhat. Not enough though for me to send it in.

My opinion is if 20 people tell you "don't send it in", that may be good advice but you will have to decide if the loss of 3-5 seconds detracts from your enjoyment. If it does, then it will be worth the loss of the watch for a couple of months to get it back with the knowledge that it had been looked at by the RSC and should then meet your expectations. I wouldn't rush into it though, pick a time that you think works best for you.

The key word in your comment is "consistent". If the gain/loss is consistent that indicates a regulation should suffice and there are no other issues to address.

It was purchased back in March 2018 by the original owner.

I then bought it from my non-AD dealer around mid-October. So whilst it's new to me, it's definitely not new :)

Just wanted to clarify:

If the COSC specifications are +2/-2 per day, and assuming I'm losing 2 seconds per day, then does that mean on Day 1 the watch will be 2 seconds slow, and on Day 7 the watch will be 14 seconds slow (ignoring daily fluctuations in deviations caused by wear, etc.)?

If that's the case, then after initially sync'ing my watch last week, and now it's 6 seconds slow, then does that mean, on average, my time loss is actually within the COSC specifications?

[Greg75]

If you set it 7 days ago. It is losing less than 1 second per day. Meaning: it is better than COSC and better than promised by Rolex. Time to relax and enjoy your watch.

If you need to get it regulated then why not go to Sydney RSC? They have always been excellent to me.

hi rolex friends, i consider myself lucky to own both the SD43 and the 2018 JCDSSD.

Based on my (limited) early experience, boh of them hardly lose or gain time (less than one second at worst) if i store them dial down overnight.

good luck!

Yes, let's have some clarification.

COSC tolerance is +6 to -4 seconds per day.
The new Rolex standard is +2 to -2 seconds per day.

Thank you for this suggestion

For the last couple of nights, I had the dial facing down, and now the watch is running +/- 0 spd after a full wind

Let's hope this precision continues

I am in the same boat with my DSSD now. It started off at just within spec, loosing an average of 1.8 seconds per day, but now that the watch is 3 months old it's consistently losing 3 to 4 seconds per day, irrespective of overnight crown position.

This is not too big of a deal, except my Tudor watches are all keeping virtually perfect time and I wish my Rolex was at least within spec.

I live in New Zealand, and I guess my Deep Sea would have to go to Australia but given it would need special pressure testing (to 12,800 feet plus 25%!!) is it possible it would have to go to Switzerland if I decide to request regulation?

I am currently travelling in Europe, and will be in Switzerland at the end of January..wonder if I could just drop it off :)

[Tigger]

I have never had any problems with Sydney RSC. However if you have reservations about taking your watch there, and if it only requires regulation I expect Karl at Master Watchmaking would do that very quickly.

[smoov]

you are v welcome, enjoy alternating between the various options till u get it within limits acceptable to you.

for me, it may come down to accepting a loss of up to 1 spd as the norm when they are worn on my wrist.

Yes. If its 6 seconds slow after one week it is losing less than a second per day.

Place it dial up at night and you may find over a week it’s bang on

It wouldn't bother me 120secs a day out to be honest.

120 seconds/day?



To be honest?

[supernova]

Are you guys serious, +-5s/d out and your talking about regulating?

At this rate, the watch is still 99.994%, if your complaining about that accuracy or if that inaccuracy is affecting your daily, then you should be buying an atomic Casio instead... I'm sure being 30 secs late for your meeting will be OK..

Please wear and enjoy the Rolex!

99.994% of what? -5s per day is outwith cosc, and 125% outwith Rolex's advertised spec.

So, yes, -5s a day on a watch that is sold as +2/-2 would bug me, yes.

Particularly when I know what this movement is capable of (mine is +2 seconds (maximum) per week)

[darkside7]

Get your watch checked with a real timegrapher for a good baseline instead of using apps.

There's 86,400 secs in a day, being out by 5s/d means the watch is still 99.994% accurate.

Faster by 5s/d means your going to be 2.5mins faster per month, unless your in a profession that needs super accurate timekeeping, I don't think that matters to the average person. I just check my watch every couple months against my phone and adjust if necessary, it is a mechanical watch at the end of the day and timing can fluctuate in many ways depending how you use your watch.

I would much rather enjoy the watch at +5s/d than worry about this and spend money getting it regulated or if under warranty, wait 8 week turnaround from Rolex. But that's just me, each to their own I suppose!

[t65tampa]

My GMT Master II 116713 is running at a consistent -5.5 seconds a day. I've thought about sending it off for adjustment, but since there isn't much fluctuation in the rate, I'd rather just keep it with me and move it forward a couple minutes ever month. All watches need service eventually, so if the variance changes or other issues arise, I'll be more willing to part with it for the month or two it would require.

I understand what you are saying, but personally I feel any product should be within the tolerances that the manufacturer has stated it will be.

Rolex has made much of the plus 2/minus 2 seconds per day and as such it's very reasonable to expect the watch to perform in that manner.

I probably won't get my 3235 regulated, even though it is averaging minus 4 seconds per day now, but I think it's reasonable to expect that it should perform as it is guaranteed to perform by the manufacturer.

Well in the real world the bare uncased movements are still tested at the COSC to a AVERAGE OF -4+6 seconds to get the certification.And in the first 10 days of testing movement could vary by 10 seconds on any single day and still pass the test.After testing movements are shipped back to Rolex passed and failed yes some do fail.The passed movements are then stored for days,weeks months,perhaps longer.Then movements are checked again in the watches case to this new spec-2+2 which is a good thing.Now when you think of regulation if you sent watch back to Rolex it could take several weeks to get watch back.So Rolex must have some sort of machine to test on several timographs perhaps many at a time as they do sell around now 850000 watches a year.In the real world just because test results on a machine the tested watch has passed this -2+2 spec in a controlled environment at time of testing.But in a uncontrolled environment results on the wrist or on a winding machine could be different.Just like they advertise the performance and fuel consumption in a controlled test environment of today's cars.Again in the real world with the many driving variables traffic how heavy the foot is on the gas pedal.It's doubtful anyone would get the exact car testing results.So just like the results of driving a car,the results of wearing a watch has many variable to over come when wearing on or off wrist.This new -2+2 spec was started first by Omega so Rolex had to follow,but for any mechanical watch to run to the COSC spec is a mechanical marvel.

[brandrea]

I wouldn’t crack open the watch for that, nope
