Haiku Review:
The Seiko Sumo SBDC033 (The Blumo)

By: Kaz Mirza

Preface: so after episode 71 of the podcast where we talked about watch writing and horology photography, I wanted to try something different. In an effort to curb my normal foul-mouthed verbosity (and to create a more efficient review free of fluff and bullshit) I’m writing a Seiko Sumo review with Haikus. Let me know your thoughts in the comments below – this was actually a lot of fun to work on.


See Current Pricing On Amazon!

First diver purchased
Two years ago for a cruise –
Expectations? None

Not too much online
And not too many reviews
But something called me

Perhaps the dial
Or it could have been the case
– something connected

Ordered the sumo
– sized the bracelet – put it on.
I never looked back.

The Case:

Though wide, case curves well
sits comfortably on wrist –
Brushed and polished steel

Long sweeping curves stretch –
connect lug tip to lug tip
– Bold but subtle case

Though the case is big
It by no means is bulky
– Balance from soft curves

Case surrounds bezel
Grips exposed at 6 & 12 –
Not common, but fun.

  ad spot

The case curvature
with the brushed and polished steel
– A dressy diver

The Dial:

Blue – blue – wide hue range
Blumo hue varies in lights
One watch – many sides

Applied round markers –
Bold matte lume wrapped in polish
– Legibility

White details contrast
leverage both light and dark
– Legibility

Beveled chapter ring
Creates depth and eye-intrigue
– Legibility

The Bracelet:

Solid steel endlinks
Tops are brushed – sides are polished
Dress/Tool – in between

Lug width an issue
Some folks feel it is too small
Small bracelet – Big watch

But dress and tool meet
When bold features are balanced
Small bracelet – Big watch

Lug to lug profile
Gives wrist presence and comfort
But strap pairings? Tough

Space from case to lugs
too large so most straps can’t fill –
Watch can look bucktoothed

NATOs are best choice
Other than stock bracelet, though-
no fault in either

The Movement:

The 6R15
Date wheel – 23 jewels
50 hour reserve

Accurate and true
Hand-wind and automatic
“Seiko, use it more.”

Final Thoughts

One watch – many sides
Dress diver meets tool diver
– Often overlooked

With Seiko divers
SKX – turtle – big names
Sumo gets sidelined

Key quality here –
Strange among Seiko divers
-where dress and tool meet

Seiko divers are
core utility drivers
-but not the Sumo

Easy to pass by
The Seiko sumo could be
But a gem to miss

Standard MSRP for the Seiko Sumo is $650. However you’ll pay much less than that online since prices fluctuate a lot (it’s currently at about $420)- so be sure to check out the current price*.
