Seiko 5 Sports Field Series automatic black dial steel bracelet 41 mm

A new vision of the Field Series collection
With the HDB006, Seiko 5 Sports HDB006 enriches its famous Seiko 5 Sports collection with a model designed for modern adventure.
Inspired by the utilitarian and military watches of the 1960s, this 2026 version revisits the "field watch" spirit with a more robust, urban and technical approach. Its shiny black dial combined with a bidirectional compass bezel gives it a strong identity, halfway between outdoor exploration and contemporary elegance. The watch takes up the historical fundamentals of Seiko: reliability, readability and excellent value for money.

An inspiration drawn from vintage military watches
The HDB006 features a 41 mm stainless steel case with 13.2 mm thickness and 48.5 mm horn, offering a strong presence on the wrist while remaining comfortable for everyday use. Its rotating compass bezel, directly inspired by the brand’s iconic Alpinist models, allows for simplified orientation outdoors thanks to the sun and cardinal points. Arabic numerals fully covered with LumiBrite are one of the great novelties of this generation, ensuring a remarkable readability day and night. The three-link steel bracelet reinforces its authentic "tool watch" style while providing a feeling of premium strength

Technical side
At the heart of the watch beats the automatic caliber Seiko 4R36, a movement recognized for its robustness and its simplicity of maintenance.
It operates at 21,600 vibrations per hour, has 24 rubies and offers about 41 hours of power reserve. The HDB006 also has a stop-second function, manual reassembly and day-date display at 3 o'clock. Its curved Hardlex glass effectively protects the dial while the transparent screwed back allows you to admire the movement in operation. Waterproof to 10 bar (100 meters) and resistant to magnetic fields up to 4,800 A/m, it supports both outdoor adventures and urban daily life.

In short
Designed as an accessible exploration watch, the HDB006 perfectly embodies the DNA of Seiko 5 Sports: a reliable, readable and versatile watch, capable of going from a hiking trail to city use with naturalness.
Its design inspired by field instruments, its functional compass bezel and its proven automatic movement already make it one of the most striking new additions to the Field Series 2026 collection.
