Seiko SBEX007/SLA025

For all the watch enthusiasts out there, it must be exciting to know that Seiko have decided to celebrate the 50th birthday of its legendary 6159-7001 diver with yet another limited-production of 1500 pieces re-issue.   The re-issued model watch has two references; where the SBEX007 is the reference used for the watch to be sold solely for the Japanese domestic market while the SLA025 is the reference for the rest of the world to go by.  Both watches are made in Japan with the only difference in the reference and serial number printed on the back for the casting.

The SBEX007 is the modern re-issued from the once known Seiko’s 6159-7001 divers watch.  While the re-introduced watch is much similar to its predecessor, Seiko have included a solid case design which made the watch allowed to an impressive water resistance depth of 300meters, which doubled any other professional diver watches in the market at the time.  To add the icing to the cake, Seiko has equipped the re-issued SBEX007 with its top of the line hi-beat Grand Seiko automatic movement at 36,000BPH.
