Spinnaker's core value is "Beyond the sea, living with the sea." The "SPENCE 300 AUTOMATIC" achieves a high-level balance between the waterproof design technology essential for realizing this value and the practicality required for everyday use.
While possessing a slim 10.9mm case, it boasts a phenomenal water resistance of 300m, breaking the conventional wisdom that "high-water-resistance models become thick."
Realizing 300m water resistance with a 10.9mm case thickness: The "SPENCE 300 AUTOMATIC" is the crystallization of Spinnaker's proud advanced design, cutting technology, and meticulous assembly techniques by craftsmen. Meticulously designed parts are combined with absolute precision, and expert engineers spent over a year to achieve 300m water resistance. Furthermore, they achieved a slim profile with a case thickness of 10.9mm. Considering it is common to have a thickness of 12-14mm to achieve comparable water resistance, this is an astonishing thinness. While thin, it possesses potential that is never modest.
Providing a comfortable fit: The "SPENCE 300 AUTOMATIC" offers a comfortable fit. With its slim case and low center of gravity, it adheres to the wrist, making it comfortable enough to forget its tough specifications, and it performs well both on and off the clock.
Vintage broad arrow hands: The dial features the characteristic broad arrow hands seen on vintage models of the past and traditional dot indices. The simple design conveys the essential charm of a diver's watch.
Applying multi-layered luminous paint: The indices are applied with Swiss-made Super-LumiNova. By applying the luminous paint in multiple layers, it glows strongly even in environments with low visibility, such as in the dark or underwater, allowing values to be read without error.
Trusted Japanese movement: Equipped with the highly reliable Miyota 9039 automatic movement. With 28,800 vibrations and a 42-hour power reserve, it is designed for precision and durability, displaying accurate time both on land and at sea.
Solid metal strap: A solid metal bracelet is used to complement the slim case. The movable range of the links is wide, providing an appropriate fit to the wrist. It is also resistant to water and sweat, making it wearable in various scenes from daily life to marine activities.
Renewed special box: The product is set in a box that evokes the feeling of the sea.

About SPINNAKER:
A classic diver's watch that goes beyond the sea and lives with it.
Spinnaker embodies the spirit of marine pioneers who have opened up the abyssal world.
The classic dot indices that increase visibility, the compressor case with a rotating inner bezel, the bubble lens inspired by submersibles... The wrists of those who challenged the unknown deep sea and stimulated human curiosity were always adorned with advanced, technically sophisticated watches.
The "classic diver's watch" provided by Spinnaker pays homage to the glorious golden age of diving and its history up to the present day, reviving the aesthetics of vintage in the modern era.
Spinnaker timepieces contain the charm and adventurous spirit of the sea, are manufactured according to high standards, utilize innovative technology and carefully selected materials, and are imbued with the craftsmanship of artisans.
Spinnaker debuted in Italy, which has produced many great divers and yachtsmen. The design, which fuses classic and diver's elements, has gained popularity all over the world, including in Italy, the UK, and France, and in 2019, it began expanding into Asia, including Japan.
The brand name comes from the sail that controls the tailwind. It is a hemispherical sail located in front of the yacht, used when sailing with the tailwind, representing the "adventure spirit" that drives one into the marine world.
