Price range £110 to £3,550 across 168 Seiko watches in stock.

The SRPD55K1 is built around a 42.5mm round stainless steel case, 13.4mm thick, with a unidirectional rotating bezel that marks it out as a sports watch. The black dial carries day and date sub-displays alongside hours, minutes, and seconds, with LumiBrite applied to both hands and indices. Hardlex crystal sits over the dial. The stainless steel bracelet fastens with a three-fold clasp and push-button release. At 170g with a 22mm lug width, it sits firmly on the wrist. Power comes from the 4R36 automatic movement, with 100m water resistance throughout.

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.
