Seiko Prospex 34mm Marine Sports Quartz - Underrated summer watch?
The Watch Box DiariesAug 3, 2025
Hi all!
Today I'm diving into the underrated Seiko Prospex Marine Quartz in both Aqua Blue and Seafoam White. A pair of summer ready, pick-up-and-go offerings complete with mother of pearl goodness.
Yes, they're Quartz. Yes, they're technically "ladies" watches. But don't let either of those things put you off. I cover Specs, wearability, legibility and whether I think they deserve more attention than they currently get (spoiler alert, yes is my answer!)
As always let me know your thoughts and remember to do all the YouTube algorithm loving things!
Specs:
Reference - SU607J1 & SUR605J1
Size - 34mm
Case - Stainless steel

The light blue dial is crafted from mother-of-pearl, a material that possesses an elegance that suits dressy occasions. At the same time, the shape of the hands and the use of Lumibrite enhance legibility in any environment, as expected of a modern sports watch. A high-quality bracelet ensures excellent comfort thanks to shorter links that allow it to conform to wrists of all sizes.
