The Seiko Sportsmatic 5 (affectionately referred to as the “Five”) was released in 1963 and was an almost instant bestseller. But the Seiko 5 isn’t just one watch, there are hundreds of different designs hence why this new ‘Customise’ collection is made up of the winning fan designs from an earlier competition the brand held. While they haven’t affected the case design too much, the biggest differences between them are the colourways and bezel, each the design winner of their respective region.
When the Five was released it brought multiple innovations including the Diaflex mainspring, Seiko’s own allegedly unbreakable mainspring, plus the Diashock shock-resistant design.
These are so popular because they are a fantastic entry-level watches and perfect for daily wear. The variety helps with a range of styles from dress to diver. There’s a Five for everyone.

The new collection has four different references, the SRPK03K, SRPK05K, SRPK07K, and SRPK08K. As mentioned before, the designs were drawn from the “Show Your Love for Seiko 5 Sports Customize your watch” campaign, asking fans to create their own designs and vote on which were best. These are the winners of that campaign and three of them are basically the same as a few archive references with the exception being the rose-gold tone design. Each of them represented a different region or country from European, Asia, Japan, and the Americas.

The European edition is features the bright orange dial with a very sport bezel. The Americas were a little more conservative with their black dial and monochromatic bezel while the Japanese took it even further with a completely silver with the removal of Arabic numerals on the bezel. Finally, the Asia design is a rose gold look made possible with a gold-plated stainless-steel case and burgundy bezel.
Each 42.5mm piece is powered by the automatic Calibre 4R36 with a 41-hour power reserve. Water resistance is 100m with a Hardlex crystal. Each has a commemorative engraving on the Hardlex crystal caseback.

These will be available in March and are limited to 1,968 pieces worldwide. They are available for pre-order on Seiko’s website right now with prices ranging from $499 AUD for the stainless-steel models and $625 AUD for the gold.
