Seiko Coutura SSC376 vs Citizen Eco-Drive AT8020-54L (2026): Which Solar Perpetual Chronograph Should You Buy?
TL;DR: Two brands, two very different takes on the solar chronograph. The Seiko Coutura SSC376 is a $525 Perpetual Solar Chronograph — a 44mm two-tone steel case, Seiko’s in-house Caliber V198, a perpetual calendar good until 2100, an alarm, and a 6-month power reserve once fully charged. The Citizen Eco-Drive AT8020-54L “Blue Angels” is a…

King Seiko vs Grand Seiko (2026): Which “Seiko” Should You Actually Buy?
TL;DR: King Seiko and Grand Seiko both trace back to the same Suwa Seikosha “flagship grade” watches of the 1960s, but they are not the same brand anymore. King Seiko (from $3,100) is Seiko’s revived sub-flagship line — hand-finished and Zaratsu-polished, but built on Seiko’s mainstream 6L35 automatic movement, with the VANAC series stepping up…

TL;DR: The Seiko Prospex Monster comes in two current forms that share the exact same 42.4mm case, the same Caliber 4R36 automatic movement, and the same 200m water resistance — but very different personalities. The SRPD29 is the classic all-black “Godzilla” that started the nickname, priced around $535–$550. The SRPE27 is the PADI Special Edition…

Seiko Presage Sharp Edged SPB225 vs SPB331 (2026): GMT Complication or Kabuki Limited Edition — Which Should You Buy?
TL;DR The Seiko Presage Sharp Edged Series comes down to two very different watches in 2026: the SPB225 ($1,400) is a 42.2mm GMT with a 24-hour hand, power reserve indicator, and calendar-linked time-difference function, built around the 45-hour Caliber 6R64. The SPB331 ($1,050) is a smaller 39.3mm three-hand-and-date, a 2,000-piece Kabuki-inspired limited edition running the…

Seiko SKX007 vs SRPD53/SRPD55 (2026): Is the Cult-Classic Diver Still Worth Chasing?
TL;DR The Seiko SKX007 was discontinued in 2019 and now sells for $300–$700 on the secondary market — more than its original $200–$250 retail price. Seiko replaced it with the Seiko 5 Sports SRPD line (SRPD53, SRPD55, and others), which is still in production at $350 retail. The SRPD upgrades the movement (4R36 hacks and…

Seiko Sumo SPB101 vs SPB103 (2026): Black or Green – Which Prospex Diver Should You Buy?
The Seiko Prospex Sumo has one of the odd reputations in Seiko’s diver lineup: a 45mm case that most people who actually own one insist wears smaller than a 42mm Turtle. Since the 3rd-generation refresh in 2019, it has come in exactly two dial colors that matter to most buyers — black (SPB101) and the…
