While starting its career as a diver’s watch, the Seiko Prospex has a versatile nature when it comes to robust timekeeping. Starting from the LX Line, the timepieces inside this series are directly inspired by the very first diver’s watch from Seiko. The crown inside the LX Line features a crown at the 4 o’clock marker and a power reserve indicator between 7 and 9 o’clock. Some of the timepieces are also GMTs. Another piece of diving equipment, the Sea Series inside the Prospex collection holds the true essence of diving equipment. With chronographs, deep-sea diving timepieces, and GMTs, the multi-faceted Sea series can be a companion for any occasion. Swaying away from the oceans, the Prospex Land series features simple, elegant dials with polished surfaces. Inspired by the robust chronograph from 1969, the Seiko Prospex Speedtimer is a true embodiment of sports timers with tachymeters and classic chronographs. Another inspiration for timepieces inside the collection is the 1975 Seiko Divers in the name of the Seiko Prospex Street series.
