Description
The Seiko 5 Sports HDB009K1 is a 41 mm automatic with the 4R36 calibre, a brown dial and a nylon strap on a stainless steel case, and its case and strap pairing sets the tone for the whole watch.
Case & crystal
The round case is stainless steel, 41 mm across and 13.2 mm thick, so the case profile is sturdy rather than slim. Protecting the dial is a Hardlex crystal. Because the case is steel and the band is nylon, the watch pairs a solid metal head with a soft, flexible strap.
Dial
The brown dial carries LumiBrite Arabic numerals and LumiBrite hands, so the lume keeps the time legible in low light. A red seconds hand adds a sharp accent, while a 24-hour inner scale and a day-date window sit alongside the main display. Surrounding it all is a bidirectional rotating compass bezel with a titanium carbide coating.
Movement
Inside is the Seiko 4R36 automatic calibre, wound by the motion of your wrist. It offers a power reserve of 41 hours, and it drives the Day-Date complication shown at the dial.
Bracelet & fit
The nylon strap closes with a pin buckle, which allows fine adjustment of fit along the strap's holes. It is a lighter, more casual alternative to a metal bracelet. You can browse more Seiko watches or compare all watches in our range.
On the wrist
At 41 mm in diameter and 13.2 mm thick, the watch has a confident wrist presence suited to men who like a substantial field-style case. The nylon strap and brown dial make it a natural everyday and weekend watch, and the 100 m rating and rotating bezel give it a sporting character rather than a dressy one.
Water resistance
The case is water resistant to 100 m, which in plain terms means it is built to cope with rain, hand washing and swimming. Keep the crown fully pushed in whenever the watch gets wet. Like any automatic, it benefits from regular attention, and our team can assist with watch servicing and repairs.
To see the brown dial and 41 mm case for yourself, visit our Mall of the South and Greenstone showrooms and try it on.

Warranty
Supplied with the 3-year international Seiko warranty, valid when purchased from an authorised retailer and registered at purchase through Cassims & Co. The warranty covers manufacturing defects in materials and workmanship; it does not cover normal wear, batteries, straps, glass, or damage from misuse or water ingress through an unscrewed crown.
Our watch service centre in Johannesburg handles warranty work, batteries, bracelet sizing and servicing.
Care guide
- Wear the watch regularly or rest it on a winder so the automatic 4R36 movement stays wound; its power reserve is 41 hours.
- Make sure the crown is fully pushed in before contact with water, given the 100 m water resistance rating.
- Rinse the stainless steel case with fresh water after swimming and dry it with a soft cloth.
- Rinse the nylon strap with fresh water and let it air dry fully before wearing it again.
- Protect the Hardlex crystal from hard knocks and abrasive surfaces.
- Arrange periodic servicing through our servicing team to keep the movement running well.
