Som tittelen tilseier, er det mulig å sei hvilket eta verk som er "best" ?? med eller uten dato..
ETA - verk...hvilket..

2892a2 går vel som noe av det bedre, men dette er veldig vanskelig å vurdere. Er jo ikke noe galt med et top-grade ETA 2824-2 heller!
ETA urverk med "top grade" eller kanskje aller helst "cronometer grade" er det beste du kan få av verk som kommer fra ETA fabrikken. Er jo også mulig å få tak i IWC og andre produsenter med ETA verk som er oppgradert til det bedre fra deres urverksavdeling. Om du skal ha et urverk med timer, min, sek og dato spiller det ikke utrolig mye etter mitt syn og du velger for eksempel 2824-2 i beste "grade" eller 2892-A2 i beste "grade", men kan man velge fritt hadde jeg valgt 2892-A2 ut i fra at det er et litt nyere urverk med bla noe lengere "power reserve" og det er vel ansett som et lite hakk vasere. På den andre siden er det urverket dyrere.. Bare å skrive om man har noe å tilføye eller rette på her folkens!
Her er for eksempel litt om ETA 2824-2 som jeg akkurat postet i en annen tråd også:
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. 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. In contrast, since the addition of the "-2" at the end of the movement number, there has been no difference between the standard and the chronometer grades in terms of the regulator mecanism, both being Etachron. 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 Elabore grade
is adjusted in three positions with an average rate of +/-7 seconds/day, with a maximum daily variation of +/-30 seconds/day;
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
an average rate of -4/+6 with a maximum daily variation of +/-5 seconds/day.
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.
