Seiko’s 5 Sports range has been on a tear since its 2019 relaunch, and you can count us fans. What started as a spiritual successor to the SKX (the SKX007 is still in our daily rotation) has ballooned into a full ecosystem of pilots, GMTs, divers, and field watches at prices that keep the door open for new collectors.
The newest additions to the lineup, four field watches under the HDB designation, borrow a feature that’s historically lived a few rungs up the Seiko ladder – the compass bezel.
Borrowed From the Alpinist Playbook
Compass bezels have been a Prospex Alpinist signature for years, so seeing one show up on a sub-$400 5 Sports feels like Seiko finally connecting the dots.
The bidirectional bezel sports a diamond-knurled alongside a lumed pearl at north, cardinal and intercardinal markings around the perimeter, and seemingly, enough grip to actually rotate the thing with gloves on.
For the uninitiated, it works like this: point the hour hand at the sun, rotate the bezel so south sits halfway between the hour hand and 12, and you’ve got a rough bearing. All of this without a phone in sight.
Four Flavors, Two Personalities
Seiko split the quartet into two pairs with pretty distinct vibes. The HDB006 (black dial) and HDB007 (white dial) ride on three-link steel bracelets with brushed steel bezels, leaning into a cleaner, more versatile look.
The HDB008 and HDB009 take a bit more of a traditional field watch approach, featuring green and brown sunburst dials paired with coated bezels in matching tones and nylon straps with leather lining underneath.
Specs That Earn Their Keep
All four watches share the same stainless steel case at 41mm wide, 13.2mm thick, with a 48.5mm lug-to-lug. The 41mm size is new territory for the 5 Sports Field range and a noticeable jump from the smaller 36 to 40mm field models already in the lineup, though Seiko offset the larger diameter with female end links and short lugs to help it wear closer to its dial than its case suggests.
Inside is the 4R36, the brand’s well-traveled automatic that hums along at 3Hz with roughly 41 hours of power reserve. It also hacks and hand-winds. The bigger functional upgrade is the LumiBrite finally making it onto the Arabic numerals.
Earlier 5 Sports Field watches only lumed the square hour markers, which always felt like a weird half-step on a watch built to be useful after dark. The whole dial now glows like a torch which is definitely a welcomed upgrade.
