I don't think jumping minutes are very common at all, right? If it took A. Lange & Söhne inventing it in 1999, it's gotta be rare https://www.alange-soehne.com/eu-en/manufacture/art-of-watch... | ||

That's just presenting improvements to a mechanism; while it isn't common, particularly for watches, and I don't know much about earlier examples, they do seem to exist. For clocks, however, there is the iconic Swiss railway clock [1], which dates back to 1944 and has a jumping minute. For those, however, the jump is actually meaningful in itself, in they're synchronized by a master clock that has a one minute impulse, and the jump is actually the moment of the impulse. | ||
