Masahiro Kikuno is a master craftsman who belongs to an exclusive
international group of independent watchmakers. These consummate artists create timepieces that reflect their deepest ideals, with no connection to commercial watch manufacturers. Kikuno's creations are deeply influenced by traditional Japanese culture. He's fascinated by a masterpiece called the Myriad Year Clock, which was built by a 19th-century Japanese mechanical genius. Containing over a thousand hand-made parts, the clock is a marvel of complex and precise engineering. Kikuno seeks to transcend that old master's achievement by giving the clock a modern rebirth in the form of an elegant wristwatch. This program documents Kikuno's exacting methods of designing and hand-machining all of the delicate parts needed to create a modern masterpiece.

The Myriad Year Clock is an interesting device:

The watch Masahiro Kikuno makes is a marvel, to be sure, but I found it striking that this multimonth project of a watch apparently uses no jewels. The reason for jewels in a watch is for longevity, they get used in important areas as low friction bearings.
The other thing I found noteworthy was this production, and it could be because it is from a Japanese company, neglects to mention that temporal hours have a long tradition outside of Asia, too. The temporal hour system has day and night always being the same number of hours, but varies how long an hour is. Temporal hours had some favor before cheap artificial light but astronomical measurements pushed the development of fixed length divisions of time.
(For those who have not watched the video, the watch made has an elaborate mechanism to move the hour markers depending on time of year, thus allowing for measuring variable length divisions of time.)
Babylonian and Egyptian clocks, for example had variable length hours, and the Greeks and Romans continued the tradition:
