Seiko Prospex Green Sumo Dive Watch SPB103J1

Seiko dive watches are about as cool as they come. Whether that be the Willard, SLA017 or the Turtle, they have a clear design language all of their own, are tough as nails, and rightly coveted by Seiko collectors, and greatly respected by the watch enthusiasts the world over.

The piece we have here is known as the Green Sumo amongst collectors, and stems from the updated Sumo range introduced in 2019. Now with the calibre 6R35 automatic power, and a fresh deep olive dial with slimmer hour markers and hands, and topped with a sapphire crystal rather than the old mineral used on previous renditions. A classic diver from Seiko, updated and better in every way than the previous Sumo iterations.

This particular piece was purchased locally in November 2020 and presents in TZ Excellent condition. The case and lugs show some light signs of wear, and the bracelet shows some desk diving marks. Please see images for full condition details.

Comes with outer sleeve, inner box, instruction booklet, warranty card dated November 2020, spare links to complete the bracelet and a Watch Vault cleaning cloth.
