商品説明
This is a self-winding model of the 1967 "International".
The dial features a sunray finish with fine radial lines.
Combined with the domed, three-dimensional shape, this creates beautiful shadows from the center to the outer edge, giving it a luxurious feel.
The cursive "International Watch Co." at the 12 o'clock position gives it a vintage atmosphere.
The Ref.804A has a beautiful case form with slender lugs.
The case is round and measures 36mm in diameter.
This is a large size for an IWC round case from the 1960s.
The crown is genuine IWC and features the "fish mark."
The movement installed is the Pellaton automatic winding "Cal.8541".
Compared to the conventional Cal.8531, it is thinner, has a quick date change function (moving back and forth between 0:00 and 23:45), and can also be hand-wound, making it highly practical.
How to operate Cal.8541
How to pull out the crown: Push your fingernail between the case and the crown and move it like a lever.
When pulling the crown, it is easier to push your fingernail between the crown and the case from the back.
Please remove the watch from your wrist before operating it.
Gentle operation can reduce stress on the crown and prevent it from coming out.
Manual winding: Rotate upwards with the crown in the normal position.
Time setting: Pull the crown and rotate upwards.
The second hand does not stop.
Quick date change: Pull the crown and move back and forth between "23:45 and 24:00" when setting the time.
1) Move 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 confirm the date has changed, move the hands back to 23:45.
This prepares the calendar to display the next day.
3) Advance the hands to 24:00.
Confirm that the date has advanced by one day.
By repeating steps 1) to 3), you can quick-set the date one day at a time.
To reduce stress on the movement, please operate slowly.
