From this very enjoyable review by SJX: http://watchesbysjx.com/2019/03/tudo...01-review.html
"The P01 is a peculiar watch, and the response to it has been lukewarm. But I like, enough to actually buy one when it arrives. Watches that go far off the beaten track are usually the province of Kickstarter brands. Establishment names rarely do anything bizarre. Tudor, however, went one better. It has reproduced an outlandish watch often regarded as a fictitious. Crucially, the P01 has historical legitimacy – as well as a sense of humour.

"As the story goes, Tudor developed prototypes for a US navy tender in 1967* – the watchmaker kept two and sent the other two to the navy, which rejected the idea and went with another watch brand instead. The story takes a detour here, for some enterprising souls in the 1990s, relying on the patents filed by Rolex for project “Commando”, created ostensible prototype watches, mostly branded as “Rolex” instead of Tudor, that appeared at various auctions. One sold at Antiquorum in 2004 for 124,500 Swiss francs.

"Now Tudor has recreated an original, based on one of the prototypes retained in its archives, the real deal, in other words. That’s amusing, slightly self-deprecating, and appealing.
"The Black Bay P01 is an unusual, fun and well conceived watch that is strikingly good value for an offbeat watch. It will reach stores in July 2019."
