This is an actual watch, with a tourbillon, that is almost entirely 3D printed. Think about it: the tourbillon – a 200+ year old invention designed by one of the greatest watchmakers to ever live, which for most of its history has been practically synonymous with hand-craftsmanship and high end watchmaking, has been produced in a working watch with a 3D printer.

You can wind it, set the time, and carry it with you. Sure, it's a bit large (a pocket watch, not a wristwatch, and they'd need to be good sized pockets to boot) not very accurate, and only runs for about 30 minutes – but none of that is what really matters. What matters is that this watch was manufactured using an affordable consumer level 3D printer (an Ultimaker 2). The whole thing is 98mm in diameter, and 93mm tall – coincidentally, exactly the same diameter as the Vacheron Constantin ref. 57260. To top it off, Laimer made all of the source files available for free! Sure there have been watch components made in the past, but this is the first (as far as we have been able to determine) entire, working watch that is 3D printed: every gear, escapement component, the case, even the balance spring and mainspring – and we have to emphasize that it's not just a collection of files, it's actually running.

The only non-printed parts are the metal pins used as the axes for the gears, and some screws and washers (aka "vitamins" as non-printed components are called in the 3D printing community).
