Seiko Prospex SFJ009P1 Speedtimer 110th Wristmaking Anniversary Watch - Limited Edition - W25439
Ref. SFJ009P1
Sits in Seiko’s upper tier here — more premium than three quarters of the Seiko watches we list, which start at £126.
Price range £126 to £3,550 across 151 Seiko watches in stock.Seiko made its first wristwatch in 1913 — the Laurel, a small dress piece that established the company as a maker of wristwatches rather than pocket watches. This Speedtimer marks 110 years from that moment, limited to 3,500 pieces, and the connection to the Laurel is not merely commemorative: the included brown calf leather strap with colour stitching is a deliberate echo of that original design, so the watch ships with two very different characters depending on which you choose. The 8A50 solar movement is the more interesting part of the technical story. It measures to 1/100th of a second, with dedicated sub-dials at 10 o'clock and 2 o'clock handling the fractions before the main 60-minute counter takes over at 6 o'clock during stopwatch use — a four-register layout that keeps each function readable rather than stacking them. At 12.9mm thick for a 42mm solar chronograph, it wears with less bulk than the movement complexity might suggest, and a six-month power reserve means the solar dependency is theoretical for most wearers. The panda dial — white field, black sub-dials — is a classic chronograph arrangement that reads well in changing light, helped by the anti-reflective coating on the curved sapphire. The screw caseback carries both "Limited Edition" and the individual serial number, which on a 3,500-piece run is worth finding.

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 explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It charges from light, and the cell behind that is designed to last a decade or more.
Quartz, automatic and solar comparedWhat size strap does it take?
20mm. 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 48.3mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
