Seiko

BeepWear lists 43 Seiko watches, from $225 to $6,800 with a median of $2,900. Twelve are under $1,000, sixteen sit between $1,000 and $3,000, thirteen between $3,000 and $6,000, and two limited editions are above $6,000. The centre of the collection is Prospex: 17 divers, ten of them Marinemaster 1965 and 1968 Heritage references, plus five Speedtimer mechanical chronographs. Around them are five King Seiko, six Seiko 5 Sports, an Alpinist, a Presage and three Diamonds Collection pieces. Every watch is inspected before listing and photographed as the actual piece.

Which Seiko lines are in stock? Prospex is the professional line and the largest group here. The divers include the Marinemaster 1965 Heritage SJE117 and SJE119 and the 1968 Heritage SLA077 and SLA079, the 1965, 1968 and 1970 modern re-interpretations, a 1975 600m professional re-creation, the Save the Ocean SLA055, the SLA021 300m and two 55th anniversary SLA039 limited editions. The Speedtimer mechanical chronographs are the SRQ035, SRQ037, SRQ039, SRQ041 and SRQ043. King Seiko is here as four KS1969 automatics (SJE109, SJE111, SJE113) and a KSK SPB457. Seiko 5 Sports covers the SNXS series, the SKX Sports Style 55th anniversary, the Rowing Blazers collaboration and the Field GMT SSK023. There is also a 1959 Alpinist re-creation, a Presage Sakura enamel, three Diamonds Collection quartz watches, and a Grand Seiko Spring Drive GMT.

What does a Seiko cost here? Under $500 buys a Seiko 5 Sports, an Essentials or Coutura quartz, or a Diamonds Collection piece. $1,300 to $3,200 is the band for the Presage, King Seiko, Alpinist, the Marinemaster Heritage divers and the Speedtimer chronographs, which is most of the collection. The limited-edition Prospex divers, the 600m re-creation and the Save the Ocean run $4,500 to $6,800. Seiko’s pricing is unusually wide for one brand, and that is the point of the brand: the $225 quartz and the $6,800 limited edition are made by the same company to the same standard of finishing at their price.

Prospex, Presage, King Seiko, Seiko 5: what is the difference? Prospex is the tool-watch line, divers and chronographs built to ISO and professional specifications. Presage is the dress line, with the enamel, porcelain and Urushi dials. King Seiko is the revived 1960s dress-sport line, now positioned between Presage and Grand Seiko, with the KS1969 case shape. Seiko 5 Sports is the entry mechanical line, automatic watches under $500 that are the usual first mechanical watch. Grand Seiko is a separate brand with its own manufacture, represented here by one Spring Drive GMT.

What is the Marinemaster? Seiko’s professional diver, descended from the 1965 62MAS and the 1968 hi-beat diver that Seiko built for the Japanese Antarctic expedition. The Heritage references here (SJE117, SJE119, SLA077, SLA079) are the current interpretations of those two watches, with 300m ratings on the 1968 pieces and Seiko’s in-house automatic calibres. Ten of the seventeen Prospex divers on this page are Marinemasters, which makes this one of the deeper Marinemaster selections you will find in one place.

Are these Seikos new or pre-owned? Pre-owned, inspected and sold with BeepWear’s guarantee, and many are recent limited editions whose runs have sold out at authorised dealers, which is why they are here at all. The 55th anniversary SLA039, the Save the Ocean SLA055 and the Speedtimer limited editions are examples. The condition, box and papers for each piece are stated on its own page.

What should you check before buying a pre-owned Seiko? On the divers, that the bezel clicks cleanly and the crown screws down, and when the seals were last pressure-tested. On the Speedtimers, that the chronograph starts, stops and resets to zero. On the limited editions, that the numbered caseback matches the papers. And on any Seiko sold as a limited edition, that the reference number on the listing matches the caseback, since Seiko issues visually similar watches under different references.

How does BeepWear list and ship these? Every Seiko is pre-owned, inspected before listing, and photographed as the actual item you will receive. Stock is one of a kind, so a sold listing comes down rather than lingering. Orders ship insured within the United States, and the authenticity guarantee, returns policy and warranty terms each have their own page.
