Sharing A lovely aged piece - IWC Caliber 8541, 30m water resistance. Almost rarely worn as it feels strange on the wrist that you will want to keep looking at it. Maybe the Porsche design ocean 2000 gets the inspiration from this piece. The dial has faded due to aging.
The original jumbo 5402 has many imperfections. The bracelet is too thin and the clasp is stamped. The clasp cannot be centered. The 15500 has heavy duty bracelet and heavy on the wrist. It’s part of evolution. Try to compare a Daytona PN vs a new 116500 Daytona and it’s the same.... 15500 for daily
