SEIKO Prospex 300M Diver Automatic SBDX001 Marine Master

A great watch, a grail, the best you can get for this money.

This is the third purchase I have made from Seiya. I am am extremely pleased with the overall fit and quality of this watch. It is a great time keeper and a hearty companion for anything the day may throw my way

Love this watch but @ 209 grams it's very heavy. Has anyone petitioned Seiko about producing a titanium version of this iconic watch? Same movement... just lighter.

Please do not make the mistake of considering the SBDX001 as a substitute for the venerable Rolex Submariner. No, the SBDX001 is an icon in its own right. With its own heritage. Its own unique and very Seiko way of achieving equivalent quality at the fraction of the price. It is a cult watch in the truest sense of the word where the sum is even greater than its considerable parts.

Sin minusvalorar el inglés, escribiré en mi lengua nativa. Recibido el pedido, y entusismado de poder disfrutar de este magnífico reloj. Un saludo..

No words will ever describe the attraction of this iconic piece. Many thanks to Seiya-san for the excellent communication and overall sterling service.

Amazing piece of horological engineering! Superb finish, very smooth bezel, accurate timekeeping. Does not wear big on a smaller (6.5") wrist. Worth every penny!

As with a lot of enthusiasts, the Seiko MM is the Japanese "grail" diver. And with good reason, this watch is easily on par quality wise with Rolex Subs/Omega Seamasters. The 8L35 movement works flawlessly - accuracy to +1 sec/daily. Definitely best bang for your buck!

Placed the order on Friday night- wearing it on Wednesday. Arrived in perfect condition. Great watch and great service.

The MM300 deserves to be a class by itself for its design, style, and function. Other reviews suggest the MM300 is slowly achieving its cult status. I already have two other Prospex watches, the Blue and Orange Shoguns and recently added the MM300 to my collection. I wouldn't trade them for either a Rolex or an Omega diver watch. Seiya's excellent and topnotch service is totaly focused on customer satisfaction. Thank you Mr. Kobayashi.

I used to think I needed one flash diver and a cheapo on a rubber strap to belt to death. One day with the MM and I realise my mistake. I need 2 MMs. If you love Seiko, spending half or a third the dollars on any lessor watch is a mistake. The MM wears bigger and smaller than you think it will - and in the best possible way. Equalling the understated perfection of this lovely piece of engineering was Seiya's service.

Arrived in good time a pleasure to work with Seiya's service is great Another satisfied customer Thanks

Perfection.

I have bought several watches from Seiya and he is always a pleasure to work with. This watch gets the most wrist time. Very well made. Movement accuracy has only improved with time. I have a small wrist and it fits fine. Does sit a little high on the wrist perhaps. Bezel is very smooth yet solid. Bezel insert should be inbedded rather than sitting on top of bezel. I have not experienced any scratching of bezel insert however. Buying a Rolex diver is so formulaic and such an obvious stab at t...

Probably the best value high-end diver's watch today. Excellent quality and attention to detail. Compared to its cheaper cousins this watch surpasses them by large margin. I bought it about a year ago and it is still my daily wearer. I had to store away my IWC because of this piece of excellent work. Seiya's service is impeccable. The watch came to the states in 3 days, the communication was fast and accurate, and this is the 2nd watch from Seiya that I've bought. I've never regretted a singl...

This has to be one of the best values in dive watches today, of all the divers I have the MM 300 is one of the best. The movement is as good or better than any of the COSC certified watches I have and the lume from this watch can be used as a night light. Another satisfied customer!
