Title: Sumo or MM300?
Post by: mike on November 15, 2014, 08:14:27 PM
Lately, I kena poison by the beauty of Seiko Prospex Divers.. Favorite ones are the Sumo and MM300.
The designs on both watches are quite similar. The watch diameter, movement and diver rating is different though, especially the price range :Confused:
The MM300 is higher range than the Sumo, one of the top range of prospex line up, but the price range can get me another nice Seiko JDM or even a nice entry level swiss watch..
Any sifu's here willing to enlighten me on the major differences between the 2 watches and whether I should save the money and get the Sumo or strike for the MM300? :Blue:

Basically, I am going to share my honest experiences owning both watches. Best for me to put my flamesuit on.  :Laughing_on_floor:

Differences? There are many. From the movement to the technology. The MM300 is using an 8L35 movement which is basically an undecorated Grand Seiko movement whilst the Sumo is on the 6R15. The 8L35 runs on a higher beat as opposed to the 6R15 I believe. Another major difference is the case. The MM300 has a monocoque case which means it is one piece. Diver rating on the MM300 is also higher than the Sumo. From the movement and tech that are in both watches, it is clear the winner is the MM300.

In terms of looks, I also favour the MM300 more. There is a refined premium feeling about the MM300 which denotes a more expensive watch whilst the Sumo is more utilitarian and feels like a workhorse. In terms of comfort on the wrist, I think both are comfortable in their own right although there is a slight feel of solidity coming from the MM300.

In pure watch sense, the MM300 is the more superior watch in every way as compared to the Sumo and is highly recommended.

Having said all this, the question is why did the MM300 left my collection but the Sumo remained? The answer to this comes from the last sentence in your second paragraph. Its our common perception on the 'value' of the watch. I felt the same way you did. I keep thinking that there is just too much money in that MM300 with similar functions to the Sumo that could be put to other uses or in another watch. The Sumo felt to me at that time to have the best value-for-money. So the MM300 was sold and the Sumo remained in my stable. Hence my choice between a Sumo or a MM300 would be the Sumo.

P/S: But if you feel that you can live with spending close to RM6,000 on the MM300, then I highly recommend the MM300. It is the superior watch to the Sumo.

Thank you for your advice G.MAC, really appreciate it. I love the MM300, but come to think of it I do not need such specifications in my daily life, probably won't even wear it to touch water. In addition of your comment, the Sumo should be fine for me, so I guess the choice will be the Sumo, then I have another spare RM4.5k to fill my fuel tank for the coming few years. :Laughing_on_floor:

I too have both watches in my collection. From a eye-candy perspective, the Sumo wins (especially the blue dial version). I got the Sumo first. Only later did I get the 300MM purely on the technology.

Thanks meoramri,

I have 2 Sumos black and orange, Used to have MM but sold it due to its tall thick case on my 6.5 wrist.

The MM is smaller case size then Sumo only taller.

But then again there is this coming LE MM SBDX012 which is expected to be release in January 2015, you may want to consider this

Thank you Yoda.
Yes, I've been noticing the SBDX012 too. If it's not too pricey, I might just go for it :Jumping:

I have had both before. As many has stated,the MM300 wins hands down .No wonder since the price point is higher. Sumo  is no slouch either.

Although this is an old post, I also think that aesthetically, the MM300 is a more balanced and nicer looking watch. The huge case and 20mm lugs kinda makes the sumo "unbalanced". And it really is hard to take ugly photos of the MM300.

Fully agree what you said in your last sentence :Dancing_banana:

There something very special about MM monobloc casing diver watch with 300m water resistance:

1. There is no need of a helium valve?
2. The back case will not have the normal screw in back case problem, eg. The change of hardened back case o-ring seal.
3? cannot hear the ticking sound at all.

My MM300 is a few years old and still keeps good time within COSC specs.

Due to photos were lost after photobucket changed its policy, I happen to have both MM300 and Sumo.

Just trying to help by sharing some of my watch photos here.

MM300 is confirmed to be discontinued by Seiko. Will there be an equivalent spec replacement model? Or just a pure die out permanently?

Well, there would be 1968 pieces of Hulk version @ SLA019J1, upgraded with sapphire crystal at long last.

Sumo, if you’re not gonna change strap, will looks nice. The lugs are too long compare to mm300. Once you change to normal strap to use in the sumo, you’ See the big gap is there. Looks awful. While mm300 lugs is just perfect to match on any 3rd party strap, almost gap less. But 1 mm300 can buy 3-4 normal sumo. Hehehe..

My vote to mm300... If we designed and released to compete with Rolex. With its simple hands and super bright lume, it's classic design is a hit among collectors.

My sumo went hot spring pool test, more than 40°c for 10 minutes, dipped into cold pool at 10°c then gone back to hot pool....continued hot/cold pools exchange for 1.5 hrs.

No vapor got inside .

Maybe Seiko diver is created just meant for hot spring spa pool.
