HBC006) Cortesy of SeikoIn October, Seiko will release nine limited-edition Edo Purple watches to celebrate its 145th anniversary, all arriving on 9 October. Of the bunch, the standout is the Prospex Alpinist. Long regarded as a cult classic among Seiko fans, it pairs a striking sunburst dial inspired by Edo Murasaki, the rich purple hue associated with Japan’s Edo period, with gold accents that elevate one of the brand’s most handsome field watches.Inside is Seiko’s in-house Calibre 6R55 automatic movement, delivering a healthy 72-hour power reserve, while the signature internal compass bezel, sapphire crystal and 200m water resistance ensure it’s as capable on the trail as it is under a shirt cuff. Limited to 7,000 pieces worldwide, the Alpinist is priced at £850 and looks set to be one of the most sought-after watches in the anniversary collection.2Seiko Prospex Speedtimer Solar Chronograph (Ref. HBJ005)Cortesy of SeikoThe Speedtimer has become one of Seiko’s biggest modern success stories, reviving the spirit of the brand’s legendary 1960s racing chronographs for a new generation. For its 145th anniversary, Seiko has given the fan favourite a regal makeover, swapping the classic panda look for a rich Edo Purple dial, contrasting black sub-dials and gold accents that somehow make a motorsport watch feel surprisingly elegant.Under the hood is Seiko’s V192 solar chronograph movement, which runs for up to six months on a full charge, meaning you can leave it in the watch box and it’ll still be ready when you are. Add a tachymeter bezel, sporty proportions and no need to wind or replace a battery, and you’ve got one of the easiest everyday chronographs to recommend. Limited to 8,000 pieces worldwide, it’ll set you back £640.3Seiko Presage Cocktail Time GMT (Ref. HCB006)Cortesy of SeikoSeiko’s Cocktail Time series has built a reputation around beautiful dials, and this might be its most striking yet. Inspired by the “Edo Murasaki” cocktail created at Tokyo’s famous STAR BAR, the dial combines a rich translucent purple finish with radial texturing that catches the light from every angle. Unlike the standard Cocktail Time models, this version adds genuine travel credentials thanks to the automatic 4R34 GMT movement, complete with a gold GMT hand for tracking a second time zone. Elegant enough for formal wear but practical enough for frequent flyers, it’s limited to 6,000 pieces world wide for £532. 4Seiko Astron GPS Solar Dual-Time Chronograph (Ref. HAB011)Cortesy of SeikoThe Astron has always represented Seiko at its most technologically ambitious, and this anniversary edition is no different. Housed in a lightweight titanium case with ceramic detailing, it packs GPS Solar technology that automatically adjusts to one of 38 time zones.Its vertically graded purple dial is inspired by the colours of dusk over Tokyo, giving the watch a more refined look than previous Astrons. Alongside world time, it offers a perpetual calendar, dual-time display and a 1/20-second chronograph, all powered by light. Limited to just 2,000 pieces world wide and priced at £2,573, this is the rarest model in the anniversary collection.5Seiko 5 Sports SKX 145th Anniversary (Ref. HDB003)Cortesía de SeikoNot everyone wants to spend four figures on a limited edition, and that’s where the £380 Seiko 5 Sports comes in. Based on the hugely popular SKX-inspired platform, it delivers the anniversary treatment at an approachable price, pairing the purple sunburst dial with gold accents and the familiar dive-style bezel.Inside sits Seiko’s dependable 4R36 automatic movement with day-date display and a display caseback, making it an ideal first mechanical watch or an easy daily wearer. At 9,999 pieces, it’s the least exclusive watch in the collection, but arguably the one most enthusiasts will actually wear every day.6Seiko Selection “Rotocall” Digital (Ref. HFL001)Cortesy of SeikoThe wildcard of the bunch is also one of the most fun. Rather than looking to the future, Seiko has revived the cult-favourite Rotocall digital watch first introduced in 1982. Its standout feature is the rotating bezel, which acts as a selector for the watch’s various functions, a clever piece of analogue interaction long before smartwatches existed.The anniversary edition updates the design with a black-coated steel case and purple aluminium bezel while retaining practical features including dual time, alarms, chronograph, timer, automatic calendar and LED illumination. It’s a reminder that Seiko’s history isn’t just about mechanical icons, it has always been one of the industry’s most inventive watchmakers. Limited to 4,000 pieces worldwide.
