Stepping up in Seiko's range

Price range £110 to £3,550 across 186 Seiko watches in stock.

A compact 38 mm stainless steel case keeps things measured and wearable, sitting close to the wrist without imposing. The orange dial is the clear focal point, bold in colour against the steel surround and lending the watch a sporting character that stops short of being loud. The automatic movement works away beneath, requiring no battery and rewarding regular wear. Proportions are well-suited to smaller wrists, and the overall package is straightforward and purposeful.

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?

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

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

Listed as men's, though at 38mm it sits in the range that suits anyone.
