Stepping up in Seiko's range
The Seiko 5 has always operated on a simple premise: put a self-winding mechanical movement into a well-proportioned case and keep it honest. This iteration in gold PVD does something the line does not always manage — it reads as a dress watch without pretending to be one. The sunburst white dial, gold baton markers and matched bracelet have genuine cohesion, and the crown sitting at four o'clock rather than the conventional three means it never presses into the wrist during wear, a small decision that matters across a long day. The 7S26 inside is Seiko's most produced automatic calibre, chosen here because it runs without complaint rather than because it dazzles. It neither hacks nor hand-winds, so setting it requires the familiar wrist-shake to get the rotor moving — worth knowing before it sits unworn for a few days. What it offers in return is a 40-hour reserve and a robustness that suits a watch you reach for casually. The folded-link bracelet keeps the whole thing to 101 grams on the wrist, and the clasp includes micro-adjustment positions for a fit that holds through temperature changes. The exhibition caseback turns the movement into something to look at, which at this level of finishing is a reasonable bonus rather than a distraction.

Learn more about Seiko
Kintaro Hattori opened a watch and clock shop in Tokyo in 1881, aged twenty-one, and began manufacturing under the name Seikosha — roughly, house of exquisite workmanship — in 1892. The Seiko name appeared on watches from 1924.
The company's significance is that it broke the Swiss monopoly twice. First on precision: Seiko was appointed official timekeeper of the 1964 Tokyo Olympics and built the quartz chronometers and printing timers to do it, and in the 1960s its movements placed highly at the Neuchâtel and Geneva observatory trials against the best Swiss houses.
Then on technology. On Christmas Day 1969 Seiko released the Astron, the world's first quartz wristwatch, accurate to five seconds a month where mechanical watches managed that per day. The consequences for Switzerland were catastrophic — employment in the Swiss industry fell by roughly two-thirds over the following decade. Seiko deliberately did not enforce its quartz patents, allowing the technology to spread.
The same year it produced the 6139, among the first automatic chronographs, and it has since introduced Kinetic, Spring Drive — a hybrid regulating a mechanical mainspring electronically, giving a perfectly gliding seconds hand — and its own dive and field lines.
Seiko remains fully vertically integrated, making its own hairsprings, quartz crystals, and even the Zaratsu-polished cases, at price points from under a hundred pounds upward.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Will the glass scratch?
It resists most everyday knocks. Hardlex is a hardened mineral glass — tougher than standard mineral, softer than sapphire.
Does it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
How long does it run for when it's not worn?
About 40 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
18mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 45.5mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's, though at 38mm it sits in the range that suits anyone.
