Αυτό που ξέρω είναι ότι για να ρυθμίσεις οποιοδήποτε μηχανικό ρολόϊ, πρέπει να υπολογίσεις τα +/- σε απο δύο μέχρι και έξι θέσεις . Πλάκα πάνω, κορώνα κάτω, πλάκα κάτω, κορώνα αριστερά, κορώνα πάνω, και κορώνα δεξιά.
Κι αυτό δεν είναι εύκολο. Θέλει πολύ υπομονή και χρόνο υπολογισμού.

What does "adjusted" vs. "unadjusted" vs. "regulated" mean?
These are terms to be used in conjunction with the discussion in section 3.2.
An "unadjusted" movement is a movement where no attempt has been made to ensure that the daily error rate in several orientations (positions) have been minimized across the positions. An "adjusted" movement, therefore, has had some extra care in ensuring that the variance in accuracy between several orientations is minimized.
For example, a watch adjusted to two positions include positions 1 & 2 from the above list (i.e. face up and crown down). Similarly, a watch adjusted for 4 positions has been adjusted in positions 1-4, and so on. Watches can also be adjusted for isochronism (i.e. constant time across varying states of wind) and temperature. Some manufacturers (Franck Muller, some Patek Phillipe) adjusts to 8 positions (the above six plus two half-way orientations); some on the forum would say that this is a bit over-the-top.
A "regulated" movement is a when the overall rate of the entire movement (either adjusted or not) is brought into correct absolute timing. Unlike adjustment, this is a simple tweak, which moves the daily rates of all of the positions up or down without intentionally changing the relative rates in positions.
