The Coutura sits at the more ambitious end of Seiko's solar range — not the everyday proposition, but the one that loads the V198 calibre with every complication it can carry. That means a perpetual calendar that accounts for leap years and short months without any manual correction needed until 2100, alongside an alarm, a power reserve display, and the chronograph, all running from charge stored across six months of full exposure. The case is 11.8mm at its thickest, which is notably lean for everything housed beneath the dial. The blue ion-plated bezel against a silver sunray dial is a deliberate contrast, and the integrated bracelet tapers toward the clasp in a way that keeps the 44mm case from reading as oversized once it is on the wrist. The double push-button release on the three-fold clasp is the kind of detail that matters daily — secure enough that it will not open accidentally, and straightforward enough that it does not require two hands to work it.

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?
No. It charges from light, and the cell behind that is designed to last a decade or more.
Is it a men's or women's watch?
Listed as men's.
