Seiko has unveiled two Prospex watches that are modern re-interpretations of landmark dive watches from 1965 and 1970.
The are sold on special fabric straps designed and manufactured expressly for use by divers.
The straps are made using a traditional braiding technique from Japan called Seichu, which is also used for decorative cords that holds a Kimono sash in its place.
They are said to be nearly four times stronger than regular Seiko fabric straps.
Braiding also makes them breathable and more comfortable to wear.
