στο πρακτικο κομματι ,οπως πολυ σωστα ανεφερε ο ΜΑΔΙΑΣ,τα πραγμτα ειναι διαφορετικα,ετσι οπως υποσχεθηκα ,αρχισα το ψαξιμο
The real accuracy at OH is consistently below 1 seconds/day, in many cases the equipment is not sensitive enough to detect the deviation.
- The consistent rates variation between the six positions are so small it is unheard off. Look at the rate and amplitude delta (maximum range), this is simply unbelievably great!
- Even after 48 hours of use in this 50 hours power-reserve watch, the precision of the watch remains extremely accurate an the range of positional variations truly excellent. This is due to the inherent accuracy of the watch and the clever use of Power Limiter using only the stable range of the power. Although it is a dangerous assumption, this seems to imply that if all watches are done this way, the clumsy and complicated Constant force mechanism used by other brands is no longer a necessary complication.

Επ, νάτο πάλι το σύστημα σταθερής δύναμης. Αυτό νομίζω ότι χρήζει ανάλυσης/παρουσίασης.

ακομα και σε amplitude 172 εχει πολυ μικρη διαφορα στο beat error και πολυ μικρη αποκλιση στο χρονο,αλλα δεν ξερω εαν ειναι μεγαλο η οχι για ενα tourbillon,αυτο ας μας το πει ο ειδικος

ειναι χρησιμο για την ομαλη παροχη και ειδικα οταν το ρολοι ειναι "ξεκουρδιστο " αρα εχει πιο "ανωμαλη" παροχη ενεργειας ,θα μπορουσα με καθε επιφυλαξη να το χαρακτηρισω σαν ABS...(?) ΜΑΔΙΑΣ?

για να ξερουμε για τι μιλαμε καλο ειναι να γινει μια μικρη εισαγωγη...θα προσπαθησω
The Gyrotourbillon combines two intertwined tourbillon cages, the first inner cage doing one rotation in 18.75 seconds and the second outer cage in 1 minute. This combination on 2 axes set at a 90° angle creates the ellipsoidal movement of the regulator that is said to isolate this very regulator from the gravitational effects on the rate in any position. While the Gyrotourbillon 1 needed 2 minutes to take all positions, this Gyrotourbillon 2 will need 5 minutes.

Once again everything has been done to ensure the best timing to this calibre. The large size 14 carat gold balance wheel regulated to 4htz, or 28800 vph, has a 12.5 mgXcm² and is adjusted through gold inertia blocks arranged around its rim.

The cylindrical balance spring has a rectangular section.

The two final curves are chosen to allow a perfect breathing and a consequent isochronism. I have not been able to know the name of these curbs. Jaeger-LeCoultre has used existing curbs, but not Phillips curbs. The spring is pinned in a traditional triangular stud and the stud holder is secured with two screws for a safe fix.

Looking at these cages below it looks like a torture cage for the balance wheel but it is apparently a magical treat to forget gravity!

The new balance Wheel has open-worked arms to decrease the overall moving weight inside the cage. The 100 or so parts of the Gyrotourbillon apparel weight 3.4 grams (while the full calibre is 371 parts). The full spherical diameter of the aluminium cage is 10.85 mm.

The power reserve indicator also has a little refinement. There's an additional hairspring to compensate the play in the gear train, so that the power reserve indicated is always the real power reserve in the main spring.

The main spring is covered on top and below with sapphire parts to reduce friction.

The cannon-pinion wheel has a new and surprising design.
The cannon-pinion wheel is used to engage the main train to the cannon-pinion, i.e. to the hands. When the watch is running the wheel is attached to the cannon-pinion through sufficient friction. When the hands are set through the crown the friction between the cannon-pinion wheel and the cannon-pinion is not enough to make the main train be driven by the cannon-pinion. In some way the cannon-pinion is by force disengaged from the main train when the hands are set.

Obviously this amazing watch is not just a chronometric machine. It is somewhat a simple watch with little additional complication

εγινε μια μικρη εισαγωγη με φωτο και μια μετρηση απο παλμογραφο σε διαφορετικες χρονικες στιγμες,απο εκει και περα το ψαξιμο θα συνεχιστει ,για την συλλογη πληροφοριων που θα μπορουσαν να βοηθησουν στο θεμα αυτο

Καλημέρα σε όλους
Λοιπών η πρώτη φωτογραφία δείχνει τις 6 στάσεις που ελέγχουμε το ρολόι
( η 6 στάση συνήθως δεν χρησιμοποιείτε )
Μετά από αυτό υπάρχει ένας συνδυασμός από πράξεις ώστε να δις το πόσο μπροστά η πίσω πάει το ρόλοι
η συγκεκριμένη Φώτο έχει και το αποτέλεσμα έτοιμο
Μην μπερδεύεστε
Και κάτι άλλο δεν υπάρχει ρολόι που να μην χάνι ( συν πλην ) ότι και εάν είναι
Ευχαριστώ

kwnsta,θα μπορουσες να μας κανεις καποιες πιο επεξηγηματικες αναφορες ,θα ειχε ενδιαφερον,ευχαριστω

Φυσικα και οχι, και για να εξηγηθω, ο πολυς κοσμος θεωρει πως επειδη τα μηχανικα ειναι πιο ακριβα θα πρεπει να ειναι αντιστοιχα ακριβή.
Έχω κουραστεί να εξηγώ///

Φίλε μου
Έχω ξανά κάνη post σε παρόμοιο θέμα και εξηγώ διάφορα
( εάν το βρω θα το ξαναβάλω )
Να ξεκαθαρίσω κάτι δεν έχω κάτι προσωπικό μαζί σου αλλά επειδή ακούω πολλά από διάφορους ‘ρολογάδες ’ για αυτό πόσταρα
