Θοδωρη παρα πολυ ενδιαφερον θεμα ανοιξες ..
συγχαρητηρια φιλε ...μπραβο

Ευχαριστω φιλε!

Φίλε Θοδωρή,

νομίζω με βάση το γεγονός ότι η η 2892 επιλέγεται από πιο ακριβές σειρές-εταιρίες ρολογιών μπορεί κανείς εύκολα να ισχυριστεί ότι σε σύγκριση με την 2824 θεωρείται ανώτερη!
Σε προσωπικό επίπεδο είμαι ΠΟΛΥ ευχαριστημένος και από τις δύο ( και από τις διάφορες εκδόσεις της 2836) στον ίδιο βαθμό!
Απίστευτα επίπεδα ακρίβειας χρονομέτρου εύκολα, σε συνδυασμό με τις τιμές τους ( πρόσφατα αγόρασα το φθηνότερο ελβετικό μου με την 2824 - ένα Camel Active στα 100€ φυσικά μεταχειρισμένο)

Ισοπαλία λοιπόν κατά τη γνώμη μου!

Φιλικά
Νίκος

The ETA 2892.
Watches with simple date complications,and crono.
So how does it compare to the competition? There are some movements that match it in terms of accuracy and reliability, but IMHO, none exceed it. The Rolex 3035 and 3135 match it yes exceed it well IMO no. But these movements are a lot thicker and considerably more expensive too. The Patek Philip, while being very pretty to look at, do not match it for accuracy and are far more delicate as far as reliability is concerned. The JLC 889/2 does match it for accuracy, but is too delicate to give it any competition in the reliability department. The main reason for the latter is its very weak mainspring. The whole design, while being well thought out and superbly executed, relies too much on everything being just perfect,like so many expensive high end watches .It is just thrown out of timing far too easily, when even minor things go out of adjustment. I don’t have too much experience on the many other movements but IMO the ETA 2892 is a good as it gets at any price or any brand.

The ETA 2824-2T

Now the size is very similar to the 2892,So,The $64000 how does the ETA 2824/2 compare to the ETA 2892-A2? Or is it as accurate and as reliable as its more costly bigger brother?.Provided that its the top range grade fitted with the highest – chronometer – grade parts, carefully lubricated and adjusted there is very little difference in accuracy between the two movements.As far as reliability both are up there with the best thats on offer today.
Now IMO to keep these movements in tip top condition they must be
serviced every 3-5 years,where say a Rolex could go longer.Now regarding Rolex one thing I could never understand was the keeping of the old fashion oscillating axle for the sake of winding efficiency.Instead of ball bearings like everybody else but (now included in the new Cal. 4130 chrono movement).Now IMO this is Rolex weakest point,and better now with the newer oils but still a weak point,ask James.Now COSC quality timing can be achieved by most good quality movements today Swiss Japanese or European with a bit of patience and skill.But with the ETA 2892 and the 2824 its very very easy to do.



Sometime I hear comments like "such an expensive watch and only an ETA movement inside ". Words like these give the impression that an ETA movement is of lower quality.It should be the other way around, people should say "Well, it has a excellent ETA movement inside this watch, but the price of this watch is astonishingly high".And they still make and sell around five million movements a year.Lets not forget that ETA is the largest manufacture in Switzerland, because they make everything, in-house only.I have a special regard for the Unitas 6497/8 this movement has not basicly changed now for over 50 years,and is capaple of COSC standards,and very forgiving in its serviceing or lack of.A truly great workhouse movement that has powered many high end watches.

This is short list of outstanding movements that should all easily achieve a daily consistency of five seconds or better on the wrist.ETA 2892-A2, ETA 2824/2, ETA Valjoux 7750,Unitas6497/8,Omega 2500, JLC 889/2 , JLC 960, all of the current Rolex calibers, Longines 990 (Lemania 8815), PP 215, PP 240, Zenith 400,Zenith 670, GP 3100 plus there are many more.

ETA 2824-2

One workhorse of the ETA mechanical line is the ETA 2824-2, The 2824 is an automatic winding, twenty-five (25) jewel movement, available in four executions or grades: Standard, Elaborated (improved), Top and Chronometer[4]. The key components which differ at the line of demarcation between Elaborated and Top are the barrel spring, shock protection system, pallet stones, balance wheel & hairspring and the regulator mechanism. To illustrate the differences in accuracy garnered by the successive grades, consider the following specifications:

* the Standard grade is adjusted in two positions with an average rate of +/-12 seconds/day, with a maximum daily variation of +/-30 seconds/day;
* the Elaborated grade is adjusted in three positions with an average rate of +/-7 seconds/day, with a maximum daily variation of +/-30 seconds/day;
* while the Top grade is adjusted in five positions with an average rate of +/-4 seconds/day, with a maximum daily variation of +/-10 seconds/day.

The Chronometer grade must meet strict standards prescribed by the COSC. Chronometer grade movements are serial numbered as that is a requirement of the certification authority. Moreover, it should be noted that the degree of decoration on the movement's parts, generally only an aesthetic improvement, increases as well with the grade.[5]

As a footnote, when servicing these movements please check the barrell teeth for wear and replace if worn, correctly lubricating the mainspring to allow the clutch to slip when under tension may help to improve the life of the barrell teeth.


ETA 2892

The ETA 2892.A2[6] is however, widely considered the more upscale of the basic ETA movements, and it certainly a newer design dating to the 1970s where as the 2824 traces its roots back to the 1950s. The 2892 is fitted with top quality components. The 2892 is an automatic winding, twenty-one (21) jewel movement, available in three executions or grades: Elaborated, Top and Chronometer. The key components which differ at the line of demarcation between Elaborated and Top are the pallet stones, balance wheel & hairspring, and the regulator mechanism. To illustrate the differences in accuracy garnered by the successive grades, consider the following specifications:

* the Elaborated grade is adjusted in four positions with an average rate of +/-5 seconds/day, with a maximum daily variation of +/-20 seconds/day;
* the Top grade is adjusted in five positions with an average rate of +/-4 seconds/day, with a maximum daily variation of +/-15 seconds/day.

The Chronometer grade must meet strict standards prescribed by the COSC: an average rate of -4/+6 with a maximum daily variation of +/-5 seconds/day. The wider range for the Chronometer grade is designed to take into account the differences in a watches rate between static positions, as when the tests are performed, and the dynamic positions as when a watch is actually worn. Chronometer grade movements are serial numbered. Moreover, the degree of decoration on the movement's parts, generally an aesthetic improvement, increases with the grade.[7]

The 2892.A2 is regarded by many horologists as being in the same 'quality' range (accuracy and reliability) as the in-house produced Rolex movements.[8] Insofar as accuracy is concerned any movement which is expected to be COSC-certified, or is in fact COSC-certified, must meet the same standards. The ETA 2892.A2 is usually found in the more expensive and prestigious watches and brands. Owing to its relatively slim height of 3.60 mm, the 2892.A2 is a favorite of watch brands that market complicated movements such as Breitling with its trademark chronograph (stop watches). Given the slim dimensions of the 2892, it provides a good platform on which to add or build a chronograph complication. It is also used in IWC's Portofino line without complications simply for its small size.


The Omega Co-axial based upon an ETA movement

Omega's popular Seamaster line of watches currently use an embellished version of the ETA 2892.A2, which is known as the Omega 1120. As an adjunct, some versions of the Omega watches may be fitted with the proprietary Co-axial escapement invented by George Daniels, an English horologist and exclusively marketed by Omega a sister company of ETA. The movement with the co-axial escapement is known as the Omega 2500 series and is derived from the ETA 2892.
