Submariner 14060M

[Webb]

I'm going to buy a 14060M submariner and would like to know if the 4 line version has a more accurate movement than the 2 line.

I have read conflicting information with some saying they are exactly the same and others saying that only the 4 line meets the Superlative Chronometer standard.

Can anyone give a definitive answer?

I prefer the cleaner look of the 2 line but accuracy really matters to me.

They are exactly the same movements, one went through COSC certification and one did not. The movement in the 2 line could be regulated to the COSC standard.

It certainly can, if regulated by an expert watch maker. My 1996 2-liner was regulated during a full service at my AD (Rolex certified watch makers) in summer 2019, and has been running consistently ca. 2 seconds per day fast since then. That's good enough for me! I check it against a radio-controlled clock about once a month...I´m not obsessed by accuracy-to-the seconds.

My two liner is the most accurate watch in my collection

What a boring question. Literally pish....Has to be Borg generated?

What an amazing contribution you have made to this thread.

Agreed! OP didn’t even ask which is the better investment. Shouldn’t the mods filter out these watch enjoyment questions before we even have to see them?

For what it’s worth, this is probably the most disrespectful watch forum that I belong to.

Personally I'd rather see threads like this, than the endless whinging about availability, or "investments", or "latest price checks".

[csaltphoto]

No idea if it is more accurate but it is different. The "M" stands for "Modified". Different caliber designation too; 3000 vs 3130. Think the "M" has a full balance bridge, maybe a few other enhancements.

Never mind, I miss-read the question. Yes the 2 and 4 line M models have the same movement.

[tifosi]

The 2 line and 4 line 14060M is exactly the same. As previously stated a 14060 has a different movement.

[hutch300]

Both are great watches and classics. I will say if accuracy is your jam you might not want an automatic watch. What are you after? Perhaps some more context and we could be more helpful.

[PepsiBezel]

Welcome!

As another poster mentioned, you may find more of a difference in potential accuracy/precision between the 14060 and the 14060M models as the movements are different.

Amongst the 4-liner 14060M models, the latest serials of them have a parachrom bleu hairspring, which may have potentially better accuracy and more anti-magnetic.

Excellent choice OP

[TunaTuna]

The two line is way cooler, thats what matters most. Either is accurate enough.

[sski]

i'd get the more elegant 2 lined dial version; as others have mentioned- movement can always be regulated by a watchmaker.

It’s because the symmetry of the two liner is unmatched. And there will never be another 2 liner sub in the future.

[GradyPhilpott]

Precision is the word we should use in this context.

A watch's accuracy is determined in relation to an official time, such as NIST or observatory time.

If I have a watch that is precise to one second in 25 billion years, it will be inaccurate, if in my haste I set it five minutes slow or fast.

I love my 14060M. Fewer lines of text are not necessarily more elegant.

In this case, they are equally elegant.

[Dazthebeard]

Great watch. Can’t recommend enough

4 liners appear to be attracting higher asking prices at the moment, probably being seen as a future collectable due to their short production run. Last of the best.

Its exactly the same movement today the COSC test is mostly purely marketing and nothing more, and its quite costly to test the bare uncased movements at COSC. Rolex has there own machine at COSC because of the many hundreds of thousands of movements they test each year. Take the Rolex Explorer they were COSC tested but watches like the 14060 and many 14060M were not tested, but exactly the same movement.Same many years ago with the old Daytona like the 6263 SS, but the gold version of the same watch was tested but SS was not.All the Rolex movements made over the past 50 odd years when regulated correctly, that matches the owners wearing habits, can run a AVERAGE -4+6 seconds a day or better so can many other brands.And will add even when regulated on a timing machine to say +2 seconds a day, this dont mean on the wrist it will perform exactly the same each day, and please remember there are 86400 seconds in day.No purely mechanical watch any brand and at any price, will keep 100% perfect time close yes but perfect no.

I prefer the 4-liner as it reminds me of the 5512 vs the 5513. I know those two had different movements, but makes me think the 4-liner is superior.

4 liner is more symmetrical.

[Andad]

My 2001 14060M is the most accurate watch I have.

Runs fast about 2 seconds/week.

I can correct that by leaving it 6 up overnight.

Last serviced about 3 years ago.

[Dilemma]

If accuracy is your primary concern you can do better than a mechanical watch but I suspect you know this.

Now. You want the two-liner. Repeat after me; “I want the two-liner I want the two-liner.” These damn fancy Subs in blue, green, gold are posers. Posers I say! And do NOT get me started on that weird goiter thing some have. Cut it off! Just cut it off!

[Webb]

Thank you all very much.

Welcome OP.

I own a 14060M (K-serial) with the 3130 movement.
Its caliber is very accurate AND very precise.

I measured Amplitudes, Rates, and Precision of 32xx and 31xx calibers.

https://www.rolexforums.com/showpost...postcount=1232

The 3130 data points were taken for my 14060M.





Even towards the end of the power reserve and at low amplitude (150 degrees) the 3130 remained very precise (0.5 s/d).

My Y series 2 liner gains less than 1 second per day...

[WBaileyii]

As so many have already said. The 2 liner and 4 liner 14060M's both have the same movement. The 4 liners were sent to COSC for certification and the two liners were not.
For me I just like the symmetry of the two liner more...

This has always been an interesting debate.

My school of thought is that Rolex routinely sends all of their movements in for COSC testing and never set aside others, that are made at the same time, only to go into Subs.

It should also be noted that a movement is only COSC tested once, then nobody ever tests it again, regardless of how it operates.

I have thought that it was a choice by Rolex to keep the Sub as near to the original look as possible, hence, a minimalist dial. Possibly it was more perception that people want a "chronometer", or they were setting the table for the ensuing ceramic COSC model.

Mine don't run any differently than a COSC version.
