Prospex SPB453

SPB45340mmautomatic$1,300 list priceAnnounced April 2024

The 2024 successor to the SPB143 family: a steel dive watch based on Seiko's first 1965 professional diver (62MAS), now 40mm with shorter lugs, 300m water resistance, a date window moved to 4:30 and the 72-hour 6R55 automatic. The SPB453 is the black-dial reference.

Creator Consensus

Creator Consensus

Positive

4 reviews: 4 positive, 0 mixed, 0 negative. 4 of 4 recommend it.

Every reviewer rates the design and dial positively. Most single out the clean black monochrome look and a case profile that appears slimmer than its dimensions, and all recommend it. Some credit tighter proportions over its predecessor, stable real-world timekeeping and scratch-resistant coating. Reservations centre on a modest official accuracy rating and a clasp without fine adjustment.

Where they differ. The bracelet divides opinion: some find the shorter links more refined, while others fault the clasp for lacking finer or on-the-fly adjustment. On value, some call it competitive in its class, while others point to similarly positioned rivals with better accuracy.

A Year With The Seiko SPB453 62MAS - Long Term Review

Video, 9 minOwner's reviewAug 2025

Very positiveRecommends

After a year of ownership, the reviewer considers the SPB453 one of Seiko's best-looking current watches. It is a compact, comfortable, understated diver with reliable accuracy and durable DiaShield coating. The main gripe is the scratch-prone aluminium bezel insert.

PositiveRecommends, with caveats

Finds the SPB453 a handsome, charming, well-sized 62MAS-inspired diver. Likes the 4:30 date for dial symmetry and praises the slim-looking case. Criticises the clasp's limited adjustment, the diver extension, the weight, faster-fading lume and the modest accuracy spec for $1,300.

[Video] Review: the Seiko Prospex SPB451 And SPB453 Divers

ArticleHands-on reviewAug 2024Words By Zach Kazan

PositiveRecommends, with caveats

Considers the new SPB the most refined affordable 62MAS-derived Seiko diver yet, with a better bracelet, a lovely dial and a smart 4:30 date. However, the movement's loose accuracy spec is a caveat, and the familiar design now leaves the reviewer personally cold.

Suits: Seiko diver enthusiasts wanting the best version of the classic 62MAS-style diver

What the review says, point by point
Dialpositive
  • Finds the blue tone on the dial and bezel rich and vibrant.
  • Calls the 4:30 date placement excellent, perhaps the best on this kind of watch.
  • Colour-matched date disappears unless needed.
  • Moving the date frees space for a full lumed marker at 3, improving symmetry.
Wearabilitypositive
  • Notices slightly tighter proportions compared with the prior generation.
  • Still chunky on the wrist but a little airier than before.
  • Character remains that of a chunky tool watch, just leaner.
Bracelet & strappositive
  • Considers the bracelet nicer than previous versions.
  • Shorter links articulate better on the wrist.
Movementmixed
  • Saw no timekeeping problems during a short test period of under a week.
  • Has no issue with Seiko using the 6R family, seen as very reliable.
  • Warns buyers who care about precision that the accuracy spec will disappoint.
Designpositive
  • Finds it more refined as a package than any comparable Seiko recalled.
Originalitymixed
  • Thinks it fittingly serves as Seiko's core diver given its heritage ties.
  • Seeing the design repeatedly over the years has dulled its appeal.
  • Now finds the design somewhat generic.
Valuemixed
  • Believes it has an edge over rivals in the $1,000–$1,500 range.
  • Accuracy spec falls short of many watches costing the same or less.
Compared with
  • Seiko Prospex SPB143: New model has a nicer bracelet, tighter proportions and feels more refined.

Hands on with the new Seiko Prospex 62MAS, improving on the SPB143 with the SPB451, SPB453 & SPB455

Video, 8 minComparisonApr 2024

PositiveRecommends

A solid, subtle refinement of the SPB143: a slimmer-looking case, better water resistance and one of the best-looking divers around. The reviewer has minor gripes about the overly smooth bezel action, a modest bracelet upgrade and the lack of a no-date option.

  • The clasp is shorter but remains a bulky three-part design. 4:27
  • More comfortable overall, though not a big step up. 4:27
  • Appreciates that drilled lug holes keep strap changes easy. 4:54
Functionalitymixed
  • Impressed that water resistance rose to 300m while the case got thinner. 2:04
  • Finds the bezel grip good, like on the SPB143. 5:24
  • Wants a clickier bezel action; finds it too smooth and too easy to turn. 5:53
Finishing & buildpositive
  • Says, from ownership experience, that the ultra-hard coating genuinely resists scratches. 5:24
  • Notes the aluminium bezel inserts are matte, lacking the SPB143's brushed finish. 5:53
Valuepositive
  • Feels the price won't break the bank. 6:51
Versatilitypositive

Reacting to the announcement, the reviewer welcomes the new 40mm 62MAS reinterpretation's size, 72-hour movement and 300m rating, calls it a good-looking tool watch at reasonable pricing, but criticises the lack of on-the-fly micro-adjustment on the bracelet.

Seiko make a microbrand move by tweaking the 20MAS

ArticleReactionMay 2024Buffy Acacia

PositiveRecommends, with caveats

The reviewer sees the new line as a refined, microbrand-style V2 of the 20MAS. Shorter lugs, a well-integrated 4:30 date, a more legible bezel and a slimmer bracelet justify the US$100 price rise, though the reviewer cannot decide which version they prefer.

Suits: People with smaller wrists; strap changers

Not a review of the watch in hand (news, a guide or a reaction), so it isn't counted.

What the review says, point by point
Case & proportionspositive
  • Keeps the 62MAS character while feeling more refined.
  • Deeper brushing makes the polished lug facets stand out more.
  • The shorter lug-to-lug is a modest change that small-wristed wearers will appreciate.
  • The reduced diameter and thickness are unlikely to be noticeable without a side-by-side comparison.
Dialpositive
  • Despite generally disliking 4:30 dates, the reviewer finds this one well integrated.
  • The circular date cutout is far less intrusive than an angled rectangle.
  • Colour-matched date wheels avoid distracting contrast.
Functionalitypositive
  • Smaller bezel numerals let the minute markers continue beneath them, improving the accuracy of elapsed-time readings.
  • The 300m water resistance probably won't matter to daily wearers but suits the watch's diving reputation.
Movementmixed
  • Considers the 6R55 only slightly more impressive than the calibre it replaces.
  • The extra hours won't change daily wear, but reaching a three-day reserve has psychological appeal.
Bracelet & strappositive
  • Smaller links should drape more easily across most wrists.
  • Drilled 20mm lugs keep it well suited to strap swapping.
Valuepositive
  • Believes the upgrades warrant the higher price.
Originalitypositive
  • Finds the update surprising, feeling more like a microbrand's second version than a big-brand release.
  • Subtle tweaks retain the design's character while improving performance.
Compared with
  • Seiko Prospex SPB143: The new model is a refined successor, yet the reviewer is unsure which to prefer.
