The Cocktail Time line within Presage began as Seiko's answer to a specific question: what does a dress watch look like when it is built around a dial rather than reduced to one. The blue here is solarised across seven layers of varnish, which means the colour shifts from pale ice to something far deeper depending on the angle — the kind of surface that reads differently across a table than it does under a reading lamp. The 4R35 inside is a solid, hackable movement with a hand-wind option, built to a tolerance that keeps it honest across most conditions. Forty millimetres sits at the practical centre of a dress watch: enough presence on the wrist to read clearly with the cuffs back, compact enough to disappear beneath them. The uniquely shaped crown gives a firm, positive grip when setting the date or winding down.

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?

Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.

Will the glass scratch?

It resists most everyday knocks. Hardlex is a hardened mineral glass — tougher than standard mineral, softer than sapphire.

Does it need a battery?

No. It is hand-wound, so it needs winding every day or two but never a battery.

How long does it run for when it's not worn?

About 41 hours fully wound — enough to survive a night off the wrist, but not a full weekend.

Is it a men's or women's watch?

Listed as men's, though at 40mm it sits in the range that suits anyone.

Cheapest place to buy

Both F.Hinds and Goldsmiths list it at £350, so choose on delivery and warranty rather than price.

Who are F.Hinds?

F.Hinds has been run by the same family since 1856 and is now in its fifth generation, with more than 115 shops across England and Wales. They are a member of the Responsible Jewellery Council and an Authorised Diamond Dealer.
