Today, Seiko introduces into the Prospex collection a range of watches based on the fan-favourite SPB143 that feature multiple enhancements in technology, design, and construction.

This marks the first time that Calibre 6R55 has appeared in the Prospex collection. The new watches are further enhanced to ensure water resistance to 300m, a first for the Prospex collection’s non-saturation diver’s watches. A change in the location of the date window from the three o’clock position to the space between four and five o’clock now allows a more symmetrical design and more space to be filled with Lumibrite, ensuring high legibility even in dark conditions.
