A distinctive Tudor diver from the brand’s pre-Black Bay era.
Built around a stainless steel case, this Prince Date Hydronaut features a woven carbon-fibre dial, unidirectional dive bezel, sapphire crystal with Cyclops date magnifier, and 200m water resistance.
Inside is the proven ETA 2824-2 automatic movement, while the Jubilee-style steel bracelet gives the watch a more refined character than a conventional dive watch.
What makes this example particularly interesting is the carbon-fibre dial — an uncommon configuration that gives the otherwise utilitarian Hydronaut a distinctly technical appearance.
Now discontinued, the Prince Date Hydronaut represents an overlooked chapter of Tudor’s modern history, from the period before the brand’s Black Bay-led revival.
