Introducing Seiko Goes Sporty For Euro Summer With The 5 Sports Field GMT & Digital Alarm Chronograph

As the Northern Hemisphere is in the midst of a seriously hot summer, and us Aussies are finally saying goodbye to grey skies, Seiko is treating us to lots of colour and a tinge of nostalgia.

First up is the 5 Sports Field GMT duo, a set of tooltastic affordables that play into the popular steel-bezelled GMT archetype, outfitted with either a subtle cream or striking green dial. Speaking of those dials, a fair bit is going on here, with most of the real estate taken up by indications and indices of some kind.

Going from the outside in, there’s that aforementioned steel bezel, demarcated in a 24-hour format as is appropriate for a GMT, matching the broad, red paddle hand. Next is a simple minutes track interrupted by lume squares (and a triangle at 12), giving way to sans-serif Arabics, surrounding yet more numerals, these completing the day-long cycle going from 13 to 24. Among all that, the 5 Sports Field GMT manages to squeeze in four lines of text - the Seiko logo and Seiko 5 branding above the pinion, with “Automatic” and “GMT” printed below it - as well as a framed date window.

In contrast, the 39.4mm case is kept very simple, with an all-brushed finish and no faceted flourishes. The crown is unsigned, the crystal is domed Hardlex, and water resistance sits at a respectable 100 metres.

Rounding out the specs, the HDB001K and HDB002K are powered by Seiko’s in-house 4R34. That means a “caller”-style GMT, where the quick-adjustment is for the second time zone hand (rather than the hour hand of a “true” GMT), a 41-hour power reserve, a beat rate of 3Hz, and a pretty wide accuracy band ranging from -35 to +45 seconds per day.

For those who yearn for the return of leg warmers and mullets (and not the poser skullet kind), Seiko has you covered when it comes to wristwear with two new renditions of the Rotocall. Yes, I know it’s not called that anymore, but "Digital Alarm Chronograph" just doesn’t have the same ring to it. The initial trio sported colourful bezels and positive LCD displays, while the new HFL002P and HFL003P go monochromatic and negative, in either silver or gold.

Functionality stays the same thanks to the A824 digital quartz calibre, with its many functions dictated by the bezel - think of it kind of like the Rolex Sky-Dweller’s digital cousin. Apart from the usual hours, minutes, and date, there’s also a split-seconds chronograph, alarms, a count-down timer, a second time zone, and, in case you’re trying to read the time in the dark, also a button that lights up the display.

The dimensions remain faithful to the original’s, with a 37mm diameter, 10.6mm thickness, and 43.5mm lug-to-lug length. These will fit a variety of wrist sizes and, by matching the water-resistance and lug width of the GMTs, will also make for a left-field sports watch option.

Long the affordable champion of Seiko’s catalogue, the 5 Sports is as charming as ever. Most of its specs make it a versatile proposition, and I especially appreciate some of the more tool-watch-oriented features like the drilled lugs and a no-frills case design. Alongside the 20mm lug width, the overall design is a great match for a number of aftermarket strap options regardless of the dial colour you choose.

Ever since its debut a few years ago, the 4R34 has made mechanical GMTs that much more approachable, and these are a great big-box brand option, though you do have to put up with the usual shortcoming of a Hardlex crystal. I’m happy to look past this for the vintage-inspired reissues, but on a sports watch, sapphire performs that much better.

The Rotocall became famous for its unique look and being favoured by several astronauts for its ease of use. Rather than fiddling with a bunch of buttons and scrolling through menus, you could access any of the watch’s functions just by turning the bezel - important when you’re wearing the not-so-dextrous gloves of a space suit. This new duo fits the 1980s bill as much as any others, though I always prefer a positive display simply for its legibility in very bright conditions. That said, I can’t deny that the gold number looks particularly tubular…
