商品説明
This is a 1974 self-winding IWC model.
The dial features a sunray finish that shines elegantly depending on the angle.
At the 12 o'clock position on the dial, the applied "IWC" logo and the handwritten "International Watch Co" company name are presented together, exuding a vintage charm.
The case features a hairline finish on both the front and sides, while the bezel has a polished mirror finish.
The case back is a screw-back type, and the crown is an authentic IWC crown with a fish emblem.
It is characterized by a beautifully flowing case design where the case and lugs are integrated, maintaining a modern impression even after nearly half a century.
The movement equipped is the Pellaton automatic winding "Cal.8541B".
It is thinner than conventional movements and is said to be the most practical Pellaton automatic winding movement.
It offers high practicality with a hacking seconds function, a quick-set date function, and a manual winding function.
Operating Instructions
Manual Winding: Rotate the crown upwards in its normal position
Time Setting: Pull the crown and rotate it upwards
Quick Date Setting: Pull the crown and move the hands back and forth between "11:45 PM and 12:00 AM" in time setting mode
1) Advance the hands to 12 o'clock at night (24:00).
If the date changes, it is 12 o'clock at night. If it doesn't change, it is 12 o'clock in the daytime.
2) Once you have confirmed the date has changed, move the hands back to 11:45 PM.
This prepares the watch to display the calendar for the next day.
3) Advance the hands to 12:00 AM.
Confirm that the date has advanced by one day.
Repeat steps 1) to 3) to advance the date one day at a time.
To reduce stress on the movement, please operate slowly.
