Dive Watch Wednesday: Reviewing the Seiko Prospex “Sumo” 50th Anniversary Limited Edition


The Seiko Marinemaster Ref. SBCD027 was introduced in 2015 as one of the special editions marking the 50th anniversary of dive watches carrying the Seiko name, together with the Seiko Marinemaster Ref. SBDX012. Because the SBDC027 offers quite a bit more upgrades and changes to the standard model, and is produced in a much larger quantities, we’re sharing this review again.

It’s the 27th version of the “Sumo” with a very balanced look — the hands, the glossy bezel insert similar to the Marinemaster’s, plus the brownish, dark dial really did change the look of the watch for the better: Both the dial and bezel have become much less busy than the ones found on the base model, and this can also be considered a positive change. Sure, the watch may be considered a bit of a “compromise” if it’s viewed as a re-edition of Seiko’s first dive watch, but overall it is a very attractive watch.

As with the regular model, I still think that the 20-mm lug size is a bit too small for a 44-mm to 45-mm case when worn with the bracelet, and I feel that the proportions of the dial (especially with the significantly smaller hour hand) tend to be a touch too small when compared to the significantly more massive bezel and case. Also, a black polyethurane strap would have been a nice add-on, and a bit closer to that of the 1965 model, as would a Seiko Hardlex crystal. Nevertheless, both the bracelet and sapphire crystal should be regarded as a most welcome upgrade from a consumer’s point of view, and the watch should certainly not be criticized for not being true enough to its past.

Speaking of close: Over the years I have seen and reviewed so many Seikos that we weren’t expecting to find anything like the dust on the hands that this one had, or lume that has been applied that unevenly, as this one did. Also, the edges of the new hands seem unusually rough when compared to what we are used to getting from Seiko, regardless of the price level. However, since we’ve only reviewed this one model of the SBDC027, I expect and hope this to be that famous “exception that proves the rule.” Who knows, maybe Seiko’s Quality Control team was already celebrating the 50th anniversary when this piece was being dispatched.

The SBDC027 is powered by Seiko’s in-house Caliber 6R15, which comes with hacking seconds and can be wound manually. It is limited to 2,000 pieces and retails for 80,000 Japanese yen (about $675*).

What we liked very much:

  • Over-delivering in most aspects: great price/performance ratio
  • The glossy black bezel insert similar to the one used for the Marinemaster
  • The elegant gray/brown dial, which is so much less busy than the one on the “Sumo”
  • For a returning customer, the SBDC027 offers more differences from to the base model than e.g. the SBDX012

What we absolutely loved:

  • An affordable option to celebrate 50 years with a limited edition
  • Great overall quality and an interesting movement alternative thanks to the 6R15
  • Great wrist presence and a great-looking Seiko dive watch

What we would have changed:

  • A black rubber or polyethurane strap in addition to the bracelet
  • The Prospex logo could have been placed only on the caseback instead of also on the dial
  • Even though sapphire is considered an upgrade to Hardlex: for a re-edition I would have preferred something more true to the history of Seiko
  • It’s seems to be a bit of a compromise to equip a contemporary model from 2007 with a new dial/hand/bezel combination in order to celebrate a rather different model from the past

    This is a nice “upgrade,” but I’m perfectly happy with my standard black Sumo as it is.

    Could you please let me know where can I buy in EUROPE one of the new SEIKO SBDCO27 ?

    • Dimitris, I have sent you a couple of links to international sellers as an answer to your direct email; it might however be even more difficult to find a dealer within Europe as you have now just further specified in this comment.

  4. Great review and yes Seiko has a much interesting dive watch history. Though the upgrades are just that, I agree with keeping it original. Hector
