The latest entry in Seiko’s regional-exclusive lineup arrives with the Prospex Sea Australasian Limited Edition “Kame”, a diver that ties together the brand’s longstanding marine-conservation narrative with a colour palette inspired by Fitzroy Island and its surrounding reef. Built on the familiar Turtle platform, the new reference introduces a distinctive dial treatment. It also continues Seiko’s annual tradition of offering market-specific variants with strong thematic roots.

What’s New

Seiko’s “Kame” edition brings a fresh interpretation to the Turtle case by combining a blue-to-green gradient dial with coordinated bezel tones. The watch forms part of the Australasian-only Prospex series, each tied to coastal landscapes and underwater ecosystems across the region. Limited to 1,000 numbered pieces, the SRPM04K deepens that theme with a design meant to echo the colours and movement of sunlit water. That approach positions the model as both a regional tribute and a continuation of Seiko’s environmentally aligned storytelling.

A Fresh Interpretation of the Turtle Case

The watch uses Seiko’s well-known Turtle silhouette, which in this edition brings a broad 45 mm case with rounded flanks, a compact lug structure and the offset crown at 4 o’clock. The stainless-steel construction is paired with a gold-toned bezel, creating a warm contrast against the cooler tones of the dial and insert. The gradient surface transitions from deep blue to green, complemented by a subtle texture that adds depth without overwhelming the layout. Large indices and arrow-style hands provide strong legibility, supported by ample lume for low-light use.

That design language continues through the diver-ready specifications, including 200-metre water resistance, a screw-down crown and Seiko’s proprietary Hardlex crystal. The watch arrives on a stainless-steel bracelet but also includes a turquoise silicone strap, reinforcing its dual role as both an everyday diver and a thematic limited edition.

Powering the SRPM04K is the automatic Calibre 4R36, offering hacking seconds, manual winding and a day-date display.

Pricing & Availability

The Seiko Prospex Sea Australasian Limited Edition “Kame” is priced at AUD 995. It is restricted to Australia and New Zealand and limited to 1,000 pieces. Deliveries begin mid-November through Seiko boutiques and authorised retail channels. Considering the regional exclusivity and thematic execution, the pricing positions the watch comfortably within the established Prospex diver range.

Final Thoughts

The SRPM04K “Kame” adds a distinct visual tone to the well-established Turtle family while keeping the usability and practicality that define the series. Its regional narrative, dial execution and accessory set make it a notable release for collectors within Australasia and an appealing limited edition for those who follow Seiko’s conservation-focused designs. It reinforces the brand’s ability to blend storytelling with daily-wear function without departing from the core characteristics that make the Turtle platform so enduring.
