Stepping up in the same colour and case shape

Price range £110 to £3,550 across 192 Seiko watches in stock.

The deep green sunray dial takes its inspiration from the Midnight Mockingbird cocktail, built up in multiple layers that shift with the light. A central needle sweeps from twelve to four o'clock to show the remaining power reserve, while the small seconds and date each occupy their own sub-dial at six o'clock. The gold-coloured seconds hand provides a quiet contrast against the green. The stainless steel case measures 40.5mm across and 14.4mm thick, with a lug-to-lug span of 47.5mm. A box-shaped Hardlex crystal sits above the dial, and a see-through screw caseback reveals the 4R57 automatic movement below. The brown leather strap fastens with a three-fold clasp with push-button release.

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?

Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.

Water resistance explained

Will the glass scratch?

It resists most everyday knocks. Hardlex is a hardened mineral glass — tougher than standard mineral, softer than sapphire.

Sapphire, mineral and acrylic compared

Does it need a battery?

No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.

Quartz, automatic and solar compared

How long does it run for when it's not worn?

About 41 hours fully wound — enough to survive a night off the wrist, but not a full weekend.

What size strap does it take?

20mm. 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 47.5mm, which suits wrists from roughly 16.5cm (6½ inches) upward.

Lug-to-lug decides fit more than case diameter does.

How to size a watch to your wrist

Is it a men's or women's watch?

Listed as men's.
