Found this one at an auction, waiting for me, and I thought that it would be a
nice one to have in the PW collection.
It is a central second, not many IWC pocketwatches have this.
It is the ref 243 from 1965. The caliber is a handwound , found in wristwtches
from that era, the cal 401, an evolution of the famous cal 89 handwound.
The case is 18K yellow gold, the dial has the sunburst pattern.
I came with a nice chain and button. Love it.
