Product Description

This watch shape is nicknamed by Seiko fans as a ‘Samurai’ - because of its angular shaped design which looks as if it were sliced by a Japanese Samurai sword. Seiko Prospex watches are designed for sports lovers and adventure seekers whether in the water, in the sky or on land. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.

In the process of replacing my Seiko divers due to burglary. Ordered a turtle from 1st class, arrived in a day within the 1 hour time slot. So impressed then went on to order a Captain Willard and a Samurai. Same great service and they price matched the Samurai. They even provide an address, phone number and promise to respond to emails. I haven’t needed any after sales but seems like a great place to buy from.! Impressed!

I got this watch for xmas gift from my wife. Never owned a Seiko before and I'm a bit fussy when it comes to my watches. I absolutely love it, looks great, feels good on wrist and time keeping is good. I'm about to buy a SRPE37K1 now. If you like a bulky divers watch, at this price you simply won't beat this SRPF31K1
