NEW! RED STAR SEA STAR – 60-Hour Automatic
Distinctive design, solid stainless steel construction, sapphire crystal and a Japanese automatic movement with an impressive 60-hour power reserve!
The new RED STAR SEA STAR, manufactured by Red Star in Hong Kong and Shenzhen, combines distinctive styling with excellent build quality. Its solid stainless steel case, unidirectional rotating diver's bezel with an aluminium insert and beautifully textured dial with a characteristic wave pattern give this mechanical wristwatch a truly individual appearance.
A high-quality, scratch-resistant sapphire crystal protects the dial. With a water resistance of 10 ATM (100 metres), the Sea Star is also suitable for everyday activities and swimming.
Generously applied luminous material on the hands and hour markers ensures excellent readability, even in the dark. The Sea Star is available with a red, green or black bezel.
Japanese Automatic Movement – Miyota 8315 with 60-Hour Power Reserve
Inside the Sea Star beats the reliable Miyota caliber 8315, a Japanese mechanical automatic movement featuring 21 jewels and operating at 21,600 vibrations per hour.
Its outstanding feature is the impressive 60-hour power reserve. This means that, when fully wound, you can take off your Sea Star on Friday evening and it will still be running on Monday morning – without having to wind or reset it.
A genuine advantage in everyday use and an attractive technical feature for enthusiasts of mechanical watches.
High-Quality Stainless Steel Bracelet with Fine Adjustment
The Sea Star comes fitted with a substantial stainless steel bracelet that perfectly complements the solid character of the watch. With a total weight of approximately 170 grams, it offers a reassuringly solid feel on the wrist.
The bracelet can be shortened by removing individual links. In addition, the clasp features a practical sliding fine-adjustment mechanism, allowing the bracelet length to be adjusted precisely for a comfortable fit.
For those who prefer a different look, we also recommend two excellent alternatives available separately from our shop: the RIOS1931 Kansas rubber strap for a sporty appearance or the RIOS1931 Montana leather strap for a more classic style.
