The cream dial takes its name from "Shiro-iro," a warm off-white shade rendered with a fine granular texture that references traditional Japanese silk. Curved hands and applied indices are shaped to catch and reflect light across the dial's surface, with a date window at three o'clock and a power reserve indicator among the complications. The dual-curved sapphire crystal carries an anti-reflective coating on its inner face, and an exhibition caseback reveals the movement beneath. At 40.2mm across and 13mm thick, the stainless steel case wears with a super-hard scratch-resistant coating. The seven-piece multi-row bracelet draws on 1970s retro designs, with short 6mm individual links that allow the bracelet to flex closely around the wrist, secured by a push-button deployant clasp. Inside runs the in-house 6R55 calibre, offering 72 hours of power reserve and rated to +25/–15 seconds per day.

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?

Yes. At 100m it is rated for swimming and snorkelling, though not for diving.

Water resistance explained

Will the glass scratch?

Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.

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 72 hours fully wound — enough to sit off the wrist over a weekend and still be running.

Will it fit my wrist?

Lug-to-lug is 46mm, which suits wrists from roughly 16cm (6¼ 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.
