With that backstory it’s easy to see how the design rationale at Apple would lead to this choice for a clock UI. Apple’s skeuomorphic design language bears Helvetica and this choice doubles down on both Swissism and skeuomorphism. The Hilfiker clock is not just the most natural choice, it’s the only choice. But, not so fast. Now the Swiss railway wants to have a chat with Apple about some copyright issues.
(There’s some irony in a skeuomorphic design language that borrows so heavily from Swiss modernism and I’m not the only one to spot it.)
