A sapphire crystal covers both the dial and movement. We still see the same overall architecture though, with pump-style chronograph pushers and a knurled crown. It’s presented in a steel or gold cased version, both measuring 39.5mm in diameter (1.5mm less than the Sport). That’s the easiest way to put it, although there’s more to talk about obviously. The new Zenith Chronomaster Open is essentially a Chronomaster Sport without the ceramic bezel and a hole in its dial. Now, just about a year later, Zenith extends the family tree with the new Zenith Chronomaster Open, taking us back to the early 2000s and dropping that sporty-looking bezel in the process. The brilliantly styled watch combined the sporty look of the ceramic 1/10th of a second scale bezel, with the signature triple-coloured subdials and the high-frequency El Primero 3600 movement.

The 1960s model had a laddered design created by specialist Gay Frères, as seen on some of Zenith’s Chronomaster Revival models recently. One area of difference is the bracelet design.
