The Cocktail Time series traces back to Ginza, where Hisashi Kishi — head bartender at Star Bar and a former world champion — mixed the drinks that gave each watch in the collection its name. The Irish Coffee takes its colour from the glass: a deep brown sunburst dial that shifts under angled light, dressed with rose-gold-toned faceted markers and dauphine hands. The box-shaped Hardlex crystal sits proud of the case in a way that adds a slight warmth and vintage distortion to the view, consistent with the formal register the whole design occupies. There is no lume at all, which is the correct decision for a watch conceived entirely for evenings after work. At 46mm lug to lug and 64 grams on the wrist, it disappears under a shirt cuff without any effort, and the proportions suit smaller wrists considerably better than most dress watches at this diameter. The smooth dark brown leather with tone-on-tone stitching is well matched to the dial, and the deployant clasp protects the leather from daily buckle wear — a practical consideration on a strap this closely integrated with the look. The 4R35 inside is not a movement to admire through the caseback so much as one to trust: it hacks, it hand-winds, and Seiko has been building it long enough that its durability is well established.

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 automatic — the motion of your wrist winds it, and there is no cell to replace.
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.
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 46mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as men's, though at 39.5mm it sits in the range that suits anyone.
