The 8T63 is a meca-quartz calibre: a battery-regulated movement driving a mechanical chronograph module, which gives it two characteristics no purely electronic chronograph shares. The seconds hand sweeps rather than ticks, and when you reset it, the hand snaps back instantly and precisely — the hallmark of a mechanical column-wheel mechanism rather than a stepped motor. That combination requires no servicing beyond a battery change while behaving on the wrist like something considerably more involved. At 41mm with a lug-to-lug of just 48mm, the case sits closer to the wrist than most chronographs at this diameter, and it will fit comfortably on a medium or smaller wrist where a more stretched case would not. The matte green dial reads clearly under poor light, and the tachymeter bezel makes this a functional field chronograph rather than one that merely references the genre. The NATO-style strap is adjustable through any punched hole with no tools, which suits a watch rated to 100m — you can swap it wet without ceremony.

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?
It resists most everyday knocks. Hardlex is a hardened mineral glass — tougher than standard mineral, softer than sapphire.
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 48mm, which suits wrists from roughly 16.5cm (6½ 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.
