Seiko Prospex 1965 Revival Diver's 3-day 300m in Cove Black
Ref. SPB453J1
Sits in Seiko’s upper tier here — more premium than three quarters of the Seiko watches we list, which start at £110.
Price range £110 to £3,550 across 168 Seiko watches in stock.The 62MAS of 1965 was both Seiko's and Japan's first diver, a 38mm barrel-cased automatic rated to 150 metres that proved itself further when members of the Japanese Antarctic Research Expedition wore it to the South Pole between 1966 and 1969. The SPB453J1 is a direct revival of that watch — one of three configurations in this release, distinguished by its all-black dial and bezel and carrying the name Cove Black. Alongside the incremental design refinements, it achieves 300 metres of water resistance, a first for Prospex outside the saturation-diving line. The movement step matters here. The earlier 62MAS revival ran the 6R35; the 6R55 fitted here adds two hours, bringing the power reserve to a full 72 hours. At 40mm with a 46.4mm lug-to-lug span it wears closer to a daily watch than a dedicated dive instrument, helped by a bracelet that has been slimmed and re-linked since the previous generation. The date sits between four and five o'clock rather than squarely at three, a deliberate shift that opens more dial space for LumiBrite and keeps the layout symmetrical — a small change that improves both legibility underwater and the overall balance of the dial in ordinary light.

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 300m it is rated for swimming, snorkelling and recreational 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 is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 70 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What 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 46.4mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
