The Seiko Prospex LX line Diver’s

A whole new diver’s to express the true spirit of Seiko

This year, the 1968 Seiko Professional Diver’s design is expressed anew in a line of Prospex watches for sport on land, in the sea and in the sky. The line’s name, LX, hints at the Latin word for light and is a subtle nod to the way that light is reflected in the broad, flat surfaces of each case. 

This diver’s watch with titanium case and bracelet is at the center of the LX line. Its design strikes an unusual balance. On the one hand, it is true to its heritage and its overall appearance reveals its strong link with the 1968 professional Diver’s. On the other, it is thoroughly modern in its execution. The center of gravity of the case is lower so that the watch sits comfortably on any wrist. The upper side of the case is set at a more pronounced angle to allow the Zaratsu-polished surfaces to shine more brightly.

Most of all, the contemporary feel of this watch is revealed in the use of Seiko’s advanced 5R Spring Drive caliber, which offers one-second a day precision alongside high levels of shock and temperature resistance. With these attributes, 5R is the perfect caliber for use in all types of sporting and adventure environment; it has been worn successfully both in space, when it travelled to the International Space Station and was worn on a space walk and at the top of the world, when Yuichiro Miura wore a Spring Drive watch on his third successful ascent of Mount Everest.

Together with the rest of the LX line, this watch is developed in collaboration with an external design team, Ken Okuyama Design. The company’s CEO, Mr. Ken Okuyama, who is known as the first ever foreign designer to design for Ferrari, has been the design adviser throughout the project.
