Seiko performed a diving demonstration experiment on the SEIKO 1000m diver's watch in cooperation with JAMSTEC. (JAMSTEC: Japan Agency for Marine-Earth Science and Technology)
JAMSTEC's Kaiko 7000 lives up to its as an unmanned probe by that can explore 7000m into the deep sea.
Seiko Prospex Depth Testing Movie
After careful preparation, the test begins.
It cleared a depth of 1000m without any problems. It goes down further to 2000m, then 3000m.
At 3000m, the back cover starts to give in, but the watch continues working.
The second hand on the 1000m Quartz stopped at 3,284m.
The glass cracked at 4,804m.
The second hand on the 1000m Automatic stopped at 4,299m, and the glass cracked at 5,993m.
There are no images of the cracked glass in this video.
A while after the experiment, I saw the watch that had been used in this experiment on display in a watch shop I happened to stop in at.
The shattered glass and severely dented back cover, which were unpublished in the video, tell the story of the severity of this experiment.
It is an amazing watch.
