Stepping up in the same colour and case shape

The 8T63 is a quartz calibre, but it does not behave like one at the chronograph. Where most quartz movements step the central hand discretely, this one sweeps in fifth-of-a-second increments, giving the elapsed-time reading a fluency that is unusual for a battery-powered movement. Accuracy runs to ±15 seconds per month, and the reset has a mechanical crispness that reflects Seiko's investment in the calibre's engineering. At 43mm the case reads as a proper sports chronograph, but 11.6mm of thickness is restrained for a movement with this many functions, and the watch will disappear under a cuff where bulkier rivals will not. The deep blue dial is textured across the main chapter, while the sub-dials — 24-hour indicator at three, running seconds at six, 60-minute register at nine — are finished with a circular grain that gives the eye somewhere to settle. The bracelet mixes brushed and polished links and adjusts by push-pin; the deployment clasp releases cleanly on both sides without requiring a thumbnail.

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.

Will the glass scratch?

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

Does it need a battery?

Yes. It is quartz, so expect a battery change every two to three years at a jeweller.

What size strap does it take?

22mm. 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 50.4mm, which suits wrists from roughly 17.5cm (7 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.
