Hands-On Seiko Marinemaster 300 SBDX001 Review

Seiko Marinemaster

Last year, I purchased a modest bunch of Seiko Replica Watch Company Reviews Mainly only for amusement only, however I immediately discovered that these are very seriousReplica Watch Company Reviews regarding what they have to bring to the table. I purchased a Seiko ‘Baby Tuna’ SRP231 after I saw it without precedent for the Seiko store in Amsterdam. I chose to ‘import’ it myself to save a fast buck (yet FedEx did an amicable offer of giving it over to customs so I didn’t need to announce it myself, or to be certain that they are getting their payoff charge from Dutch traditions). Next up was a Scuba 200 meters (SBDC001) otherwise called the ‘Sumo’, a SKX007 and a vintage 6309-7049 .

Now, it is here!

All greatReplica Watch Company Reviews that rundown well under 500 Euro (or USD besides). At the point when I purchased the Seiko SBDC001, I likewise had a look at its more costly (> $2000 USD list value) Seiko Marinemaster 300 sibling with reference number SBDX001. This model, the Seiko Marinemaster Automatic Professional 300 SBDX001 looked very comparable yet I wasn’t into Seiko enough to pull the trigger on that one.

Now, a couple of months after the fact, the Seiko Marinemaster 300 is on my wrist a little while and it is the ideal opportunity for a review.

Seiko SBDX001

Let’s start by giving you some foundation data on this model. I’m almost certain that in the event that you looked for the Seiko Marinemaster 300, you’ve presumably as of now read your offer about this watch. This Replica Watch Company Reviews Company Reviews is a strong intriguing watch however isn’t precisely new to the game. The Seiko Marinemaster 300 was at that point presented in the mid 2000s. Be that as it may, the absolute first Seiko jumpers Replica Watch Company Reviews Company Reviews was at that point presented in 1965 (the Seiko reference 62MAS-010).

Reference 6215 and 6159

Although Seiko chose to present a 50th commemoration adaptation of the Seiko Marinemaster 300 I am assessing here, the genuine progenitor of the Marinemaster 300 was not delivered until 1967 (reference 6215) and maybe the reference 6159 from 1968 looks significantly more like the current Seiko Marinemaster 300 SBDX001.

50 years or somewhat less, it is more history a portion of its Swiss or German partners have with their plunging Replica Watch Company Reviews Approximately 50 years of creating divingReplica Watch Company Reviews implies that you can be certain that Seiko realizes how to manage genuine jumping and createReplica Watch Company Reviews that can withstand the pressing factor jumpers (and their Replica Watch Company Reviews insight at extraordinary profundity. That, yet they additionally know the important prerequisites on ease of use and readability.

Prospex – Professional Specifications

I am no jumper myself, I scarcely even swim, yet I do cherish the look and feel of divingReplica Watch Company Reviews and have (had) a lot of them from different brands. This Seiko Marinemaster 300 is essential for the ‘Prospex’ scope of Seiko, which implies ‘Professional Specifications’ or ‘SeriousReplica Watch Company Reviews for genuine sports’ as Seiko puts it on their own site. The previously mentioned Sumo and Baby Tuna are likewise essential for that Prospex range however, as are the Kinetic models we’ve discussed here .

So, what makes this Seiko Marinemaster 300 stand-apart from, let’s say, the less expensive SBDC001 ‘Sumo’ model for example? It is a much heard inquiry since I’ve worn this Replica Watch Company Reviews Company Reviews really (concerning numerous individuals Seiko is being related with < 1000 USD watches).

Seiko MM300 versus Sumo

On the photograph above, you’ll see the Seiko Marinemaster 300 on the left and the Seiko Scuba (Sumo) on the right. I’ve put them both on the elastic lash that comes with the Marinemaster 300, since I like the vibe of them and am ‘not ready’ for the Seiko wristband yet (more later).

Similar Appearance

The appearance of theseReplica Watch Company Reviews is very comparative, conceded. In any case, the thing that matters is in the subtleties obviously. The Seiko Marinemaster 300 utilizations a development (type 8L35) said to be founded on the Grand Seiko type 9S55 however less more pleasant (optically) wrapped up. Since the Seiko Marinemaster has no presentation back, the development can’t be noticed. Nonetheless, in you’ll locate an inside and out article on the 8L35 development. The Sumo has Seiko type 6R15, which can be found in various Seiko Replica Watch Company Reviews It is essentially a development of the 7S types, with more force hold and some other little improvements.

Monobloc Case

If we turn theReplica Watch Company Reviews around, they actually look very much like yet note that the Seiko Marinemaster 300 has a monobloc case. This implies the case comprises of two sections (and not three), so the dial, hands and development need to come out by means of the front of the Replica Watch Company Reviews Company Reviews (after evacuation of the bezel and the precious stone). Much the same as the first Omega Seamaster Ploprof 600M ( we assessed that one here ), the utilization of a monobloc case likewise implies a helium get away from valve (as seen on the Rolex Sea-Dweller for instance) isn’t necessary.

The case back has the “Tsunami” logo and Seiko engraved a touch of data on model name and number, development type number and its chronic number. The case back has an excellent brushed completion (on both), where the brush on the Seiko Marinemaster appears to has a more profound grain too. The etching on the Seiko Marinemaster 300 is likewise more keen, maybe on the grounds that it has been engraved while the content on the Sumo case back is by all accounts ‘pressed’ into the pure steel.

High Quality Finish

The finish of the instance of the Seiko Marinemaster 300 is of exceptionally excellent, with its cleaned and brushed aspects it can without much of a stretch compete to its Swiss competition. The Sumo is pleasant too, and has decent brushed drags for instance (see beneath) that you don’t see on some Swiss +/ – €1000 Euro watches. I try to say that this SBDC001 Sumo can compete toReplica Watch Company Reviews from Swiss producers that have a multiplied sticker price of this Seiko.

Case and Crown

However, let’s adhere to the Seiko Marinemaster 300 for the present. The case estimates 44mm in distance across and is 15mm thick. Notwithstanding these measurements, it really wears unobtrusive as the bezel distance across is more modest and the drag to-haul size is very long. The crown is situated at 4 o’clock, which keeps it from staying into the highest point of your hand (leaving marks). One of the principal things you will see is that the crown is unsigned. This may be a touch of let-down from the outset, yet it impeccably takes after those first Seiko reference 6159 diverReplica Watch Company Reviews who likewise didn’t have a marked crown.

Glossy Bezel

The photograph beneath will likewise show the lustrous bezel from very close, which isn’t pottery, however hardened steel with veneer (and some cleaning has been done obviously). It looks magnificent however remember that it very well may be scratched obviously. The bezel is not difficult to handle and snaps delicately multiple times per 360 degrees turn. There’s practically no play in the bezel, which makes it a strong accomplice for genuine jumpers. The pearl at 12 o’clock utilizes Lumibrite (like the dial and hands, yet more on those later) and is very luminous.

Lug Holes

As said, the case is pleasantly wrapped up. The case band has a little brushed part and the upper and lower calculated parts are profoundly cleaned. The case is marginally bended however the case back is level which makes it a comfortable Replica Watch Company Reviews Company Reviews on the wrist. You could say the case back is tonneau formed (as presented previously). The drags have openings in them, so you will actually want to change the arm band or tie yourself utilizing an appropriate device. The Replica Watch Company Reviews Company Reviews comes with a treated steel arm band and the elastic lash as imagined in this article.

Dial and Hands

As I’ve previously composed, the subtleties have the effect with this Seiko Marinemaster 300 and the dial and hands are truly something else. To begin with the hands, these have a quite inconspicuous brushed completion and are loaded up with a grayish hued Lumibrite material. Lumibrite is Seiko’s answer to Super Luminova. Lumibrite must be charged by (daylight obviously and will gleam in obscurity for around 3 – 5 hours, contingent upon the openness to daylight or fake light. I haveReplica Watch Company Reviews with a wide range of iridescent material, similar to tritium, (Super) Lumoniva and Lumibrite and I can say that this Seiko Marinemaster (or some other Seiko I own with Lumibrite) is quite great in regards to its luminosity.


Back to the hands however, under a nearby of great importance, moment and seconds hands of the Marinemaster 300. It shows the brushed hour and minutes hand and a cleaned seconds hand. It additionally exhibits the exceptionally clear and sharp printing of the lettering on the dial. The entire hour markers are loaded up with Lumibrite, where the hour markers at 12 o’clock, 9 o’clock  and 6 o’clock have various shapes from the others. They are totally caught in silver shaded rings and casings giving it a tasteful look. It was at that point utilized in those absolute first models from the 1960s, where Rolex actually utilized tritium markers just (and rings didn’t came until the 1980s). For somewhere in the range of an ace, to others a con. I really like these metal hued edges and rings around the hour markers.

The minute track is imprinted on the external ring, which is under a little point making the genuine dial look somewhat more modest than it truly is.

Rubber Strap and Bracelet

Now for the tie, or wristband.. The Seiko Marinemaster 300 is being conveyed with both a treated steel wristband and an elastic lash. The wristband looks very like the Omega Speedmaster Professional arm band concerning the plan. In any case, the catch looks altogether changed. While there is literally nothing amiss with the comfort of the arm band (you can even effectively change the catch utilizing a slide), it is the completion of the wristband that doesn’t satisfy the remainder of this Replica Watch Company Reviews You can discuss whether comfort prevails upon it optical completion, yet I believe that in this value range this is the place where Seiko has a couple of steps to make to compete with the wristband from the Swiss and German competition. The equivalent goes for the arm band on the Sumo SBDC001 that I have. I just took them off as I feel it isn’t comparable to the remainder of the Replica Watch Company Reviews There are a ton of outsiders that hop into that hole and make truly decent looking and strong inclination elective arm bands for the SBDX001 and SBDC001 (and other Seiko models for that matter).


So, I just put on the elastic that accompanied it, and truly like it. It takes after the elastic lashes those first reference models went ahead. A few group don’t care for the little triangle shapes on it, however the 20mm haul size makes it simple to add any sort of tie you need. There is a major determination of appropriate calfskin lashes or elastic Isofrane ties that will consummately coordinate the Seiko Marinemaster 300.

Concerns about the SBDX001

Any different cons about this Replica Watch Company Reviews Perhaps not something negative essentially, but rather the precious stone isn’t made of sapphire however made of Hardlex all things considered. Seiko’s Hardlex material won’t break like sapphire when it is being harmed however, it simply breaks yet will in any case be in one section. Hardlex will be simpler to scratch than sapphire however. Thick sapphire precious stones for divingReplica Watch Company Reviews appear to be as yet relative costly so cost may have been the conclusive factor here.


Last yet not least, the accessibility of this Replica Watch Company Reviews Company Reviews in Europe is still somewhat problematic. The Seiko Marinemaster 300 is formally traded to Germany and France and has a €2000 Euro list cost over yonder. I couldn’t imagine anything better than to see this Replica Watch Company Reviews Company Reviews at more European Seiko retailers (the Amsterdam shop of Seiko additionally conveyed it in their import area) so individuals can witness firsthand how this Replica Watch Company Reviews Company Reviews from Japan compares to the typical suspects from Switzerland.

Value for Money

Whether this has to do with the strategy of Seiko in Japan on their methodology of business sectors outside Japan or that Seiko retailers are not prepared for it (yet) isn’t known to me. I unquestionably feel this Seiko Marinemaster 300 ought to be out there and accessible to any individual who is into mechanical jumping Replica Watch Company Reviews This way, the buyer can see (and feel) for himself whether the Seiko Marinemaster 300 is a fascinating option in contrast to the typical suspects. I’m regardless persuaded this Seiko is extraordinary incentive for cash (something long time proprietors and authorities of Seiko’s proficient jumpers definitely knew) and can without much of a stretch compete withReplica Watch Company Reviews made in Europe that have more exorbitant cost labels on them.


Now, in 2015, Seiko just put the 50th commemoration form of this Seiko Marinemaster 300 SBDX001 available. The reference SBDX012, with gold accents on the bezel and dial. Lettering on the dial is additionally gold hued. Just 1000 of these pieces are being made and the majority of them have been sold as of now. Under two photographs of the SBDX012, one along with the vintage 1968 reference 6159-7000. Photographs by Stefan Mollin ( ).
