Seiko is celebrating its 145th anniversary with a four-watch limited edition series that pairs two Presage models with two Prospex divers, each using a blue and white palette drawn from the brand’s identity.
The quartet is a neat snapshot of modern Seiko, moving from porcelain-dial craftsmanship to accessible mechanical dive watches without losing the practical character that defines the brand.
Ruri blue porcelain gives Presage the standout dial
The most refined piece in the set is the Presage 145th Anniversary Limited Edition Arita Porcelain HCC007J, which uses a traditional Japanese porcelain dial finished in a deep Ruri blue glaze.
Unlike Seiko’s earlier white Arita porcelain models, this version leans into a saturated blue tone, with subtle depth created by the raised chapter ring and fluted central dial texture.
The watch comes in a hard-coated stainless steel case measuring 39.6mm across and 12.4mm thick, with a polished bezel, brushed lugs and a black LWG-certified leather strap.
Inside is Seiko’s automatic calibre 6R51, a time-only movement running at 21,600 vibrations per hour with a useful 72-hour power reserve.
The Arita Porcelain edition is limited to 1,500 pieces and priced at £1,600, making it the most expensive and most craft-led watch in the anniversary group.
The Shironeri Presage turns silk into dial texture
The second Presage model, the 145th Anniversary Limited Edition Classic Series Shironeri HCC004J, takes its inspiration from traditional Japanese silk rather than porcelain.
Its pure white dial uses an irregular radial pattern designed to recall folded fabric, with blue hands, blue markers and a matching dark blue LWG-certified leather strap.
The 38mm super-hard-coated stainless steel case has a tactile bezel edge and a flared crown, giving the watch more wrist presence than its dress-watch proportions suggest.
It is also the more everyday-friendly of the two Presage models thanks to 100 metres of water resistance.
The Shironeri edition also uses the calibre 6R51 automatic movement with a 72-hour power reserve, and it is priced at £900 in a limited run of 2,500 pieces.
The 1965 Heritage Diver gets anniversary colours
On the Prospex side, the 145th Anniversary Limited Edition 1965 Heritage Diver’s HBC005J is the most classically Seiko of the four watches.
It pairs a silver-white sunray dial with a blue unidirectional rotating bezel, while LumiBrite-filled hands and markers keep the watch firmly in tool-watch territory.
The 40mm super-hard-coated stainless steel case follows the compact, faceted language of Seiko’s 1965 diver-inspired models, with short lugs and alternating brushed and polished surfaces.
Water resistance is rated to 300 metres, placing it above older 200-metre versions and making it the strongest pure dive specification in this anniversary series.
The watch runs on the automatic calibre 6R55, which adds a date display between 4 and 5 o’clock while retaining a 72-hour power reserve.
It is priced at £1,300 and limited to 4,000 pieces, supplied on a super-hard-coated stainless steel bracelet with secure clasp and slide adjustment.
The Samurai keeps the entry point approachable
The Prospex 145th Anniversary Limited Edition Samurai Mechanical Diver’s HBB001K brings the same silver-white and blue theme to one of Seiko’s more angular dive-watch shapes.
Its 41.7mm stainless steel case uses the sharp, faceted geometry associated with the Samurai line, paired with a two-tone aluminium bezel that marks the first 15 minutes in grey.
The dial keeps the anniversary look with a silver-white finish, blue accents and the broad hands and markers expected of the model.
As the most accessible watch in the collection, it uses Seiko’s 4R35 automatic movement with date and a 41-hour power reserve.
Water resistance is 200 metres, and the watch is delivered on a stainless steel bracelet with bevelled centre links, secure lock, push buttons and slide adjustment.
At £560 and limited to 9,999 pieces, the Samurai is the easiest route into the anniversary line and likely the one aimed most directly at everyday Seiko dive-watch buyers.
Taken together, the four watches make a smart anniversary release because they do not chase a single collector profile.
The Arita Porcelain model is the dial-lover’s choice, the Shironeri is the restrained daily dress watch, the 1965 Heritage Diver is the serious Prospex option, and the Samurai brings the celebration to a far wider audience.
