Seiko Celebrates the Reef with the Prospex Kame Limited Edition
Seiko strengthens its commitment to regional exclusives with the launch of the Prospex Sea SRPM04K “Kame”, a limited edition available only in Australia and New Zealand. Created as part of the brand’s ongoing Save the Ocean initiative, the model supports marine conservation projects while drawing visual inspiration from the tropical waters surrounding Fitzroy Island in North Queensland.
Part of the Save the Ocean Initiative
Beyond its aesthetic links to the coastline of North Queensland, the SRPM04K plays an active role in marine conservation. Seiko Australia maintains a partnership with the Cairns Turtle Rehabilitation Centre (CTRC), an organisation located on Fitzroy Island that rehabilitates injured marine turtles from the Great Barrier Reef. The region is home to six of the world’s seven turtle species, several of which are endangered.
As part of this collaboration, Seiko has adopted a rehabilitating turtle named “Kame”, the Japanese word for “turtle.” A portion of each SRPM04K sale is donated directly to the CTRC to support its ongoing work..
Case and Bezel
The SRPM04K uses the familiar Seiko Turtle case, a shape originally introduced in the 1970s and brought back to prominence in recent years due to its ergonomic construction and reliability as a diver’s tool. The stainless steel case measures 45 mm in diameter and 48 mm from lug to lug, with a screw-down crown positioned at 4 o’clock and a water-resistance rating of 200 metres. Although the measurements sound substantial, the curved profile and compact lug span help the watch sit comfortably on a variety of wrist sizes.
For this edition, Seiko adds a distinctive touch by equipping the watch with a gold-toned bezel. This is paired with a bi-colour bezel insert in blue and green (teal), a combination that subtly echoes the glimmering reflections found on a turtle’s shell when illuminated by sunlight.
Dial Inspired by Fitzroy Island
The dial is where the model’s regional theme is most evident. Seiko has chosen a blue-to-green fumé gradient that shifts from lighter tones at the centre to deeper shades near the edges, capturing the colour transitions of Fitzroy Island’s surrounding waters. The surface features a gentle textured pattern reminiscent of light filtering through shallow waves.
The watch maintains the traditional Prospex diver layout, with large Lumibrite-filled indices, an arrow-shaped handset designed for clear underwater visibility, and a day-date window at the 3 o’clock position. By combining a vibrant colour palette with proven functionality, Seiko ensures that the watch is both visually striking and immediately legible.
Movement: Seiko 4R36
Inside the case is Seiko’s 4R36 automatic movement. This calibre offers a power reserve of approximately 41 hours and operates at a frequency of 21,600 vibrations per hour. Known for its reliability and ease of maintenance, the 4R36 is widely used across the Prospex line, ensuring consistent performance and straightforward servicing.
Straps and Wearing Options
Seiko supplies the SRPM04K with two wearing options. The first is a stainless steel three-link bracelet fitted with a folding clasp with micro-adjustments. The second option is a turquoise silicone strap, equipped with stainless steel pin buckle.
