Seiko’s 5 Sports line is at its best when it remembers the simple appeal of a robust automatic watch at a sensible price.
The latest SKX SNZH additions do exactly that, bringing two more polished colourways to a steel sports watch that still sits firmly in accessible territory.
Formal White and Tweed Green give the model a smarter edge without sanding away the practicality that makes the 5 Sports formula work.

At a glance
- Seiko has added Formal White and Tweed Green editions to the 5 Sports SKX SNZH range.
- Both use a 42.5mm stainless steel case, 100m water resistance and the automatic Seiko calibre 4R36.
- Each version is priced at £340, or approximately $460.
A sport watch with a more tailored mood
The 5 Sports SKX SNZH remains a substantial watch, measuring 42.5mm across and 14.2mm thick in stainless steel.
That gives it the wrist presence expected from a modern Seiko sports piece, while the 100m water resistance keeps it practical for daily wear, wet weather and poolside mishaps.
The crown sits at 4 o’clock, a familiar Seiko detail that helps reduce pressure against the back of the hand during more active use.

It’s a small ergonomic choice, but it’s one that matters if the watch is worn while cycling, travelling or moving around all day.
Formal White is the cleaner of the two new executions, with a white dial, yellow gold-coloured hands and markers, and a black bezel insert carrying a matching 60-minute scale.
Tweed Green takes a more tonal approach, pairing a green sunray-brushed dial with a matching green bezel and rose gold-coloured accents.

The green version has the more quietly distinctive personality, especially as the brushed dial shifts with the light rather than relying on loud colour.
Both watches lean into a slightly dressier idea of sport, the sort of watch that wouldn’t feel out of place at a summer match, a weekend lunch or under a casual office cuff.
The 4R36 keeps things honest
Inside both versions is Seiko’s calibre 4R36, an automatic movement that has become one of the brand’s dependable workhorses.

It runs at 21,600 vibrations per hour, or 3 Hz, and offers a 41-hour power reserve.
The movement drives hours, minutes, seconds, day and date, giving the watch everyday usefulness rather than a stripped-back display.
An exhibition caseback allows a view of the calibre, which is a welcome touch at this price even if the movement itself is more functional than decorative.

That’s part of the appeal here.
The 4R36 is familiar, serviceable and widely understood, which suits a watch designed to be worn often rather than treated too preciously.
Pricing that suits the 5 Sports brief
At £340, the Formal White and Tweed Green editions sit in a part of the market where mechanical watches still need to justify themselves on specification as much as style.

Seiko’s proposition is straightforward.
You get a steel automatic watch with a bracelet, day-date display, 100m water resistance and a design that can move between casual and smarter settings without trying too hard.
The case size won’t be for everyone, particularly those who prefer vintage-leaning proportions, but the bolder stance is part of the SNZH character.

For buyers looking for a first automatic, a durable weekend watch or an affordable Seiko with a little polish, these two colourways make a strong case.
