    Another "which one" thread...the current Sbbn031 Tuna or MM300 SBDX023?

    I currently own a black bezel Tuna, SBBN031 and do really like it. But, I have been eying the latest MM300 with black ceramic bezel and sapphire crystal. I've never seen one in person, nor do I have access to one. For those of you that have experience with both which do you prefer? Side note, the fact that the Tuna is a quartz is not an issue to me. Does the MM300 fit, finish, craftsmanship, wrist presence worth the 2.5X price jump? The Tuna is unique and interesting but so is the case of the MM300. Which do you like and why? I have room for 1 Seiko in the box.

    thanks

    I would stick with your Tuna, having said that, do you have multiples of any brand? Maybe all you need is a overflow smaller box!

    Comes down to personal preference. I’ve owned nearly every variant of tuna I think. Love the design and history but prefer to wear more traditional watches so don’t have one now. The MM is a jump in quality, finish, movement, and price. Not a must have if you like your tuna.

    I have owned a SBDX001, a SBDX011 and a SBBN013, and in the end only the SBDX001 is the only keeper of the trio. Whilst I love the unique design and history behind the Tunas, the MM300 does feel more finely finished. The Tuna are obviously very well made, but they feel a lot more like a tool watch, less polished. In the end, I prefer the versatility of the MM300, as I wear shirt to work 4 days a week.

    Although I never liked the MM300 I'd say for your case it would be better to go with the MM300 since you only want to have one. The SBBN031 is as formal looking as a tuna could be and it is still quite obviously a sports watch due to its case design. Mind you the bracelets on them are basically the same.

    If it were me I'd save some more and get the MM600. In fact that's what I'm doing right now.

    The Tuna is more than capable of giving the MM a run for its money but for me the MM300 still rules.

    I have both SBDX017 and SBBN031. Definitely MM300 is of different league. Its polishing, its mono block case, its weight and presence on wrist, its applied indices ... justify the higher price. I shall never sell my 017.

    The MM and Tuna is like comparing a G-Class with a Maybach

    While Tuna is awesome in its own right, but the MM is a whole different playground. The finishing if the dial, the brush and polish, fit and finish, all are more than a step up

    Worth 2.5x price jump? Well, it sells quite well thats for sure, I've seen people who bought it and rarely see one (that I personally know), flip it

    Would I buy?

    Nope, wont buy either one, not because they are bad, but they make me look like Im wearing a power ranger armband on my puny wrists... hahaha

    I think it depends on what you're looking for in a Seiko diver. I had a SBDX001 MM300 and sold it years ago, but I still have two Seiko Tunas in my collection. I enjoyed my SBDX001, but it wore a tad too top heavy for me (I have 6.5" wrists). I loved its combination of polished and brushed surfaces and its case design. This watch is certainly more versatile as a daily wearer.

    I've also come to enjoy the unique design of my SBBN033/013 Tunas, their heritage, and grab-and-go convenience. My Tunas don't wear well under tight fitting dress shirts, and I do wear dress shirts nearly everyday. That said, I still wear my Tunas regardless. I find that I prefer their design and grab and go convenience over the more versatile MM300.

    I owned the previous gen of the MM300 (was it the SBDX001??) - is it bad I don't remember the model number? It was the one with the Hardlex crystal and non-ceramic bezel. I've also owned a number of Tunas, including the previous gen Darth Tuna, the SBBN017, the SBBN035 "Ninja Tuna," - all of which are gone - and I now own the current SBBN031.

    Yes without a doubt the MM300 is a step up in detailing and finishing quality. I think it is more versatile given that it can be both sporty and dressy. For me it was actually TOO dressy. It looked so good, I was afraid to wear it half the time. And given my normal very casual attire, it just didn't fit my lifestyle very well.

    The SBBN031, on the other hand, is also great looking, but there is no doubt it's a tool watch and very sporty. I have no problem wearing it anytime. It fits my personality and/or wants/needs in a watch better than the MM300.

    There is also the matter of automatic vs. quartz. I actually prefer the grab & go convenience of quartz. And I wasn't fond of the idea of sending the MM300 off every 4-5 years for servicing.

    It all depends what you like and what you want in a watch. For me the SBBN031 is a better choice. (And it's actually my favorite Tuna to-date)
