Q1: Is the big date instant‑jumping?
A: The big date advances stepwise over a few minutes around midnight – this is normal for this caliber.
Q2: Can the second timezone hand be adjusted independently?
A: Yes. The second timezone hand is independently adjustable, typically via a specific crown position or an additional pusher, depending on the case design. The movement supports this function.
Q3: What does ‘hand fitting height 2‘ mean?
A: This measures the distance from the movement‘s upper plate to the hand mounting plane. It determines the required hand tube height. When choosing hands, ensure they match this specification.
Q4: Will the gold plating fade?
A: Under normal use, the movement is protected inside the case, so the plating will not fade. However, moisture ingress due to failed seals can cause oxidation.
