The Seiko 145th Anniversary Edo Murasaki collection is the third and final wave of Seiko's year-long anniversary programme, and by far the most visually adventurous. The third phase of the brand's anniversary program introduces six limited-edition timepieces designed to capture a sense of creativity, optimism, and anticipation for what lies ahead. Their common thread is an unusual and deeply rooted Japanese colour: Edo Murasaki. Where the first wave used gold to celebrate Seiko's past and the second used blue for its present, the Seiko 145th Anniversary Edo Murasaki collection uses the purple of old Edo — Tokyo's historic name — to represent Seiko's future. Six models, spanning the Prospex Alpinist, Presage Cocktail Time GMT, Prospex Speedtimer, Astron GPS Solar, Seiko 5 Sports SKX, and a digital Rotocall revival, all arrive in October 2026, priced from $450 to $2,900.

What Is Edo Murasaki — and Why Did Seiko Choose It?
Edo is the historical name for Tokyo, used until 1868 when the city was renamed following the Meiji Restoration. During the Edo period (1603–1868), a distinctive shade of purple — made from the roots of the murasaki plant — became closely associated with the city's merchant culture and aesthetic. Seiko gives Edo Murasaki a contemporary expression across the new anniversary editions, using the colour to symbolize creativity, new ideas, and the desire to continually rethink the familiar.
The choice is personal as well as cultural. Seiko's founder Kintaro Hattori opened his first watch and clock shop in Tokyo's Ginza district in 1881 — the founding location that the Astron GPS Solar celebrates on its caseback, and the neighborhood that has defined Seiko's identity for 145 years. Edo Murasaki connects the brand's future-oriented anniversary theme to the very streets where Seiko began.
1. Prospex Land Alpinist — $900 | 7,000 Pieces

The first of the six anniversary timepieces brings the distinctive Edo Murasaki colour to Seiko's modern Alpinist, a three-hand field watch with a rotating compass inner ring. The model draws on the spirit of the Laurel Alpinist, Seiko's first sports watch, which was introduced in 1959.
The 39.5mm case (12.7mm thick, 46.4mm lug-to-lug) wears on a cow-leather strap with a three-fold clasp. A super-hard coated case with sapphire crystal and inner anti-reflective coating, 200m water resistance, and 4,800 A/m magnetic resistance back up the adventure credentials. Powering the Alpinist is Seiko's automatic Caliber 6R55, which provides approximately 72 hours of power reserve. The exhibition caseback shows the movement. LumiBrite on hands and markers ensures legibility in darkness.

Case: 39.5mm × 12.7mm | Water resistance: 200m
Movement: Cal. 6R55 automatic | 72-hour power reserve
Limited: 7,000 pieces | Price: $900
2. Presage Cocktail Time GMT — $625 | 6,000 Pieces
The second anniversary timepiece brings the spirit of Japanese cocktail culture to Seiko's Presage Cocktail Time collection. The elegant GMT watch draws inspiration from the Edo Murasaki cocktail, an original creation developed in collaboration with Hisashi Kishi, owner and head bartender of the renowned Star Bar in Tokyo's Ginza district, where Seiko is headquartered. The watch's finely textured dial features the distinctive radial pattern characteristic of the Presage Cocktail Time series, here bathed in a deep purple tone. The gold-coloured Seiko logo and skeletonized GMT hand add a sophisticated contrast.
The collaboration with STAR BAR makes the Presage the most narratively specific watch in the collection — it is the only model tied to a real-world place and a real person, and the cocktail's specific deep-purple hue is distinct from the more general "Edo-murasaki" of the other five models.
The 40.5mm case (12.8mm thick) wears on a five-row bracelet. The transparent caseback shows the movement. Powering the Presage Cocktail Time GMT is Seiko's automatic Caliber 4R34, which provides approximately 41 hours of power reserve and features a stop-seconds mechanism for precise time setting. The gold-coloured 24-hour hand tracks a second time zone.

Case: 40.5mm × 12.8mm | Water resistance: 100m
Movement: Cal. 4R34 automatic GMT | 41-hour power reserve

3. Prospex Speedtimer Solar Chronograph — $750 | 8,000 Pieces
The third special edition brings Seiko's 145th anniversary celebration to the Prospex Speedtimer collection. This solar chronograph draws inspiration from the iconic Speedtimer designs of the 1960s and 1970s, combining historic motorsport influences with contemporary technology and everyday versatility. A key design element is the bi-colour aluminium bezel with tachymeter scale, a detail found on a highly valued Speedtimer model from Seiko's vintage archives.
The 41.4mm case (13mm thick, 45.9mm lug-to-lug) wears on a three-row bracelet with curved sapphire crystal and anti-reflective inner coating. The solar-powered Caliber V192 drives the chronograph and offers a power reserve of approximately six months when fully charged, with 1/5-second increments for the 60-minute chronograph, a 24-hour hand, small seconds, date display, and power reserve indicator.

The Astron GPS Solar is the most expensive and rarest watch in the Seiko 145th Anniversary Edo Murasaki collection — 2,000 pieces at $2,900, in a 43.3mm titanium case with ceramic and titanium bezel (13.4mm thick, 49.5mm lug-to-lug). The dial features a horizontal pattern with varying widths between the upper and lower sections, enhanced by a gradient finish that creates a sense of depth and refined texture.
The watch is powered by Seiko's GPS solar Caliber 5X83, which combines light-powered autonomy with satellite-controlled timekeeping. The movement offers approximately six months of power reserve when fully charged, or approximately two years via the power-save function. Its extensive range of functions includes a 12-hour chronograph in 1/20-second increments, a perpetual calendar until February 28, 2100, world time for 38 cities, dual-time functionality, a day display, and a power reserve indicator, along with GPS signal reception with automatic time adjustment.

5. Seiko 5 Sports SKX — $450 | 9,999 Pieces

Seiko 5 Sports SKX 145th Anniversary HDB003K1 — $450, 9,999 pieces. Image: © Seiko via WatchTime Based on the popular SKX design, this special edition combines the collection's recognisable sports character with a contemporary interpretation of Japanese aesthetics. The purple dial showcases the unmistakable SKX dive watch aesthetic and reinforces the model's sporty character. Gold accents, including the Seiko 5 Sports logo, add a refined contrast. Also not to be overlooked are the day and date displays, representing two of the five key features that gave the collection its name.
The 42.5mm case (13.9mm thick, 46mm lug-to-lug) is water-resistant to 100m with a curved Hardlex crystal and unidirectional bezel with black aluminium insert. The Seiko 5 Sports SKX Series Seiko 145th Anniversary Limited Edition HDB003K1 is powered by Seiko's automatic Caliber 4R36 with approximately 41 hours of power reserve.

6. Seiko Selection "Rotocall" Digital Revival — $595 | 4,000 Pieces
This digital timepiece takes us back to the 1980s, when Seiko was shaping the future of electronic watchmaking with innovative designs and pioneering technology. The final model in the anniversary collection is inspired by the iconic Rotocall from 1982, bringing a distinctive retro character together with contemporary functionality. The quartz watch combines a black hard-coated steel case and bracelet with a purple aluminium bezel. Gold-tone accents add celebratory highlights.
The 37mm case (10.6mm thick, 43.5mm lug-to-lug) is the smallest and thinnest in the collection. The Caliber A824 provides a wide range of digital functions, including a rotary switch, counter function, chronograph measurement of up to 100 hours in 1/100-second increments, a single-time alarm, a timer of up to 100 minutes, a full automatic calendar until December 31, 2074, a dual-time function, a battery life warning function, and internal LED illumination.

The Bottom Line
The Seiko 145th Anniversary Edo Murasaki collection covers more ground in one six-watch release than most brands cover in an entire year. A $450 mechanical diver, a $625 cocktail-inspired GMT, a solar chronograph, a GPS satellite watch, a 39.5mm Alpinist for hiking, and a 1980s digital revival — all unified by one of the most culturally specific anniversary colours in recent watch history. Purple is rarely a neutral design decision, particularly when it's applied so generously to six models ranging from a classic mechanical sports watch to a satellite-connected chronograph. Seiko has pulled it off. For the complete official information, see Seiko's 145th anniversary page. For more Seiko coverage, see our Seiko collection archive and our limited edition watch guide.
