Ez meg, hogy hogyan tesztelik:

Először megcsináltatják a COSC minősítést:
The testing of every Rolex Superlative Chronometer watch begins with the movement’s initial testing in-house, immediately after the movement’s assembly is finalized. Once this first, base level testing is performed, every uncased movement is shipped over to the independent Swiss Official Chronometer Testing Institute (COSC). Here, in COSC’s Saint-Imier facilities, the uncased movements will be rigorously tested for accuracy under a variety of circumstances. A total of fifteen days they spend enjoying the hospitality of COSC, where the movements are held in a total of five different positions and are submitted to three different temperatures. During these tests, the watches are checked to run within a maximum average deviation between -4 and +6 seconds per day. Those movements that pass this long and thorough tests become COSC Officially Certified Chronometers.
Majd ha az megvan (kb. itt véreznek el a jó órák, amik "csak" COSC minősítettek):
Once they are back at Rolex’s facility in Bienne, where the entire production of all movements is performed in a single complex. The 92,000 square-meter, state of the art manufacture in Bienne was inaugurated in 2012; this facility, the size of 13 football fields spread out over 4 above - and 3 underground floors. We shall take a more in-depth look at it in a dedicated article.
The returned, COSC-certified movements are taken into stock and, once their time comes, are transferred to the Rolex’s facilities in Geneva, where the final assembly of watches happens from components sent in by the various facilities of the brand. It is also here, in the Genevan manufacture, that final quality control takes place. The movements, case, dial and bracelet are all assembled into one complete watch that can, at last, begin its Superlative Chronometer tests, performed in-house, by Rolex.
After casing the movement, Rolex first tests the precision of each watch over a 24-hour cycle in seven static positions as well as a rotating rack, in accordance with an exclusive methodology that simulates real-life wear. The tolerance criteria at this point are much stricter than the those for the official certification when it comes to the average rate deviation – that is watchmaker’s speak for the daily precision as perceived by the wearer. The deviation for all Rolex Superlative Chronometers must not exceed -2 to +2 seconds per day after casing.
Ennyit errő már ;)
És nagyjából az is meglehet már, hogy miért állítja az a Rolex, hogy minden egyes darab órája körülbelül 1 év alatt készül el. Ára ennek megfelelő. Nem Tamagochi tábornok szarja őket szállítószalagon icike-picike mosógépek mellett készítve ;)
(Ha már Seiko-zl, akkor hoztad volna példaként a Grand Seiko-t, mondjuk árban azok is millió forintok felett vannak. Ugyan ott nagyobb a pontosság, de a karbantartási idő meg katasztrófa, rossz nyelvek szerint 3 évente szét kell őket dönteni, hogy pontosak maradjanak)
