Seiko Prospex SSC911P1 Speedtimer 'Go Large' Solar Chronograph Watch - W24202
Ref. SSC911P1
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.The Speedtimer line reaches back to Seiko's work in professional sports timing, and this 41.4mm variant — the one enthusiasts call the Go Large — came from a deliberate choice to push the classic panda dial up to a scale that reads at a glance under pressure. The 39mm siblings are the restrained option; this one is for a wrist that wants the chronograph to announce itself. A 164-gram stainless steel watch on a tapered bracelet sits with some presence, and the silver sunburst dial with black sub-dials rewards angled light in the way panda configurations tend to. The tachymeter bezel in aluminium keeps the profile from feeling over-engineered. The dual-purpose 60-minute counter and power reserve indicator is a sensible economy — one sub-dial carrying two jobs leaves the layout uncluttered. What the solar calibre adds here beyond convenience is the six-month reserve when fully charged, which means this goes on a wrist that wants a chronograph ready without ceremony. The 1/5-second increment timing and magnetic resistance to 4,800 A/m are details that suit the watch's sporting brief, even if most owners will wear it well away from a starting line.

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 comparedWill it fit my wrist?
Lug-to-lug is 45.9mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
