Hands-On: H. Moser & Cie Endeavour Tourbillon Concept Tiger's Eye Limited-Edition Watch
As part of Watches & Wonders 2021, H. Moser & Cie released a pair of Endeavour Tourbillon Concept watches with Tiger's Eye stone dials. A somewhat old-school material (that isn't very easy to source), Tiger's Eye is a uniquely appropriate material for a brand like Moser to use in such a special piece. I spent some time with the red gold model with the deep red Ox's Eye dial, though there is also a white gold variant with a blue Falcon's Eye dial. Limited to 50 pieces each, these are definitely aimed at a very specific type of buyer that appreciates and understands just what Moser is doing.A few weeks ago, I read another article on this watch that repeatedly claimed that you can't tell the time on this watch, which is simply not true. Like Moser's other concept dial watches, there are no markers on the dial, but the hour and minutes hands are there and legible. I have a Moser concept dial of my own, and I can, indeed, tell what time it is.

Here are some words from him about the book, and from the book:ABOUT THE ANTIKYTHERA MECHANISMThe Antikythera Mechanism is an elaborate and quite well-made astronomical instrument, the earliest artifactual evidence of the ancient use of toothed gearing, and at the same time, it is the world's oldest computer.The main purpose of the instrument was to show, on its fron
