Is Tudor as accurate as Rolex ?

[imranahmed]

I recently fell in lovw qitha grey dial Tudor Iconaut which apart of being a chronograph has gmt function too. I tested it for 7 days and observed it lost 2 secs per day. I was impressed. My son told me that this is the first trendy watch that I have worn. It is 43 mm in diameter and has shiny s/s case.
What are your views about Tudor's

[andypandy]

No good home should be without a couple of Tudors. I have an early 70's Sub. and
an early 50's Oyster. Both keep v.g. time but who cares ? All my watches are vintage,
if you want accuracy , buy a quartz Timex. I get the odd remark about wearing " The
poor man's Rolex". I point out that my 1967 GMT and my 1942 Oyster are in my safe
at home , along with my 1952 IWC , 1956 Superman and my 1969 Seiko Automatic.
Watch Snobs....don't you just hate them ? Imran-Ji , did you just "fall in love" with it
or did you buy it ? Let us know ?

Any watch no matter what the brand is only as accurate as what its been regulated to perform too.And a ETA or Valjoux movement in a Rolex Tudor can easily perform to the same COSC standard as Rolex.But they may need a bit more regulation to keep them there over the years.

Now below is the copy of the European Chronometer Din certificate for my Dreadnought watch as you can see +0.4 seconds a day.Not bad for a so called humble ETA 2824-T2 movement,less than half a second a day and at the time watch cost £400,this same movement is found in many Rolex Tudor. And if a Chrono the Valjoux 7750 has one of the highest first time pass rates in proportion to any movement tested at the Swiss COSC although the Tudor line is not tested.

Padi,
It "seems" to me that the ETA movements need servicing more frequently. 4-5 years, and there is typically a small issue that needs to be addressed with a service. You never hear of a 20 year-old watch with an ETA movement that is keeping time within COSC standards (at least I never have).

Do you find this to be the case?? (I realize Rolex watches should be sent in for a service every 5 years also.)

ETA movements are supplied in several quality and finish.

Those movements even occur in the most expensive watches, Frank Muller and IWC use them.

The most complicated IWC ever made (Il Destriero Scafusia)even was 7750 based.

A 1990's ETA can absolutely function within COSC norms, no problem.

Everything depends on servicing it, a 3135 from 1990 without service won't operate within COSC, almost impossible.

ETA is a very good manufacturer and delivers very high value for money.

Though i'd never buy a $4K used SS watch with such a movement.

Jason,
My 35 Tudor Sub runs well within COSC specs as do all my other Tudors. Now you know have heard of one too!

Cannot see why any ETA or any other movement if serviced and regulated properly could still perform to COSC spec for 20 years of longer.Regarding service if watch is used in a environment say underwater or very dusty,then watch should be serviced as per manufactures schedule.But a watch will normally tell you when its needs a service timekeeping will deviate from the norm, but thats not always the case.Myself if its not broke why fix it have gone well over but not with any watch if I was using for diving etc.Now take the Unitas 6497/8 now this movement has hardly changes in almost 50 years of production. And has powered many a high end watch brands Panerai for one,and very forgiving in its service or lack of.A huge balance wheel and a very very accurate simple manual wind movement.Other very fine movements from ETA are the 2892-A2 ETA 2824/2T, ETA Valjoux 7750,but chronometer grades.Now ETA make 5 grades in most of there range,now in most of the high end watches they use a Chronometer grade movement.But even the bog standard movement with a bit of patience and careful regulation could be made to perform to the COSC standard.

I have 3 tudors dating back to the late 80's and early 90's. All with ETA movements. They keep time just as well as my Rolex's. My Tudor Chrono with the Val 7750 keeps better time then my Daytona with the 4030 movement. Both are from 1993. But I am talking seconds here over periods of weeks and comparing them to time(dot)gov.

If you find a tudor you like at a price you like AND you want it you shouldn't hesitate to buy it. Rolex has never dissapointed me with a Tudor product.

Thanks for responses. Andy I did buy the Tudor Iconaut with grey dial cost me around GBP 2100 after discount.

A great choice and great watch

[gmaines]

My tudor keeps great time, just as good as my Subs.

Congrats Tudor's are great watches. Post up some pics of yours.

That's a badass looking watch!

[taxico]

i'm not sure if it helps, but i believe the 775x movements (used in tudor and other chronos) have a semi-fine regulating device.

other tudors (eg, a 76100 full sized sub, or a hydronaut 2) have upgraded the stud/screw to a triovis fine regulating device, which makes the job easy and precise.

to be fair, most watches can be adjusted to certain accuracy, but not all would be capable of running at a stable X seconds/day.

what i have noticed is that my non-chrono tudors (past and present) have very little positional variance and are very "stable" and have never slipped despite rough use.

[chris russell]

and the fact that Rolex is casing them up means they are using the best grade of ETAs, handling them with the best of care and providing the best service.

That said, ETA movements are not designed to have the kind of positional accuracy and isochronism as Rolex, nor are they researched as thoroughly for long-term reliability. That's the reason Rolex watches use overcoil balance springs made of exotic materials, (Parachrom), and other refinements that can't be feasibly included in ETA movements for economic reasons.

It's about more than the basic regulation. Any good watch can be regulated to stay well inside COSC specs in daily use, at least until it needs service. Every Rolex I've ever owned, (a half-dozen or so), has done more than that; they keep the same timing within less than a second a day regardless of what position they are left in at night. The only other mechanical watches I've had that do that are the 8500-Series Omegas. It's admittedly not a huge thing, nor something everyone would notice or care about, but it does prove to me that there's a reason Rolexes cost more than Tudors, and no apology necessary from either Rolex or Tudor.

[imranahmed]

Hi Wolfgang I will do so but your watch is exactly like the one I bought !!

[Lion]

If you like the watch that is all that matters......do enjoy!!!

[Singslinger]

Ina word - Yes.

[andypandy]

Imran-Ji , I Love a Happy Ending ! Wear your Tudor in Good Health !

Well its only quite recently the Parachrom was introduced to other movements other than the Daytona chrono. And its not in all Rolex movements yet,Rolex like many others were forced into making there own escapement parts for the first time.Now for the last 4 decades Rolex has used the Breguet type overcoil hairsprings made by ETA Nivourox.And the ETA Chronometer grade movements are tested exactly the same way as any other Swiss Chronometer movement in 5 positions and temperatures.Now ETA make 5 grades in most all of there movements including a top chronometer grade. And they are as accurate and long lasting as any chronometer grade watch with proper care and service..

[Nomoresubs]

My 74000 Tudor bought in 1997 keeps excellent time, in fact I dont see any diference in that and my 1977/78 5513 sub, Nice watches.

[gmaines]

Keeps perfect time...Love it...

[padi56]

The only reason they are not rated is simply down to the cost to test each movement at the COSC.Rolex uses the top grade chronometer movements like the ETA 2824-2T and Valjoux 7750. ETA make 5 grades in most of there movements only difference they are just not sent for testing, but more than capable of the COSC standard.
