The Seiko Prospex Marinemaster SLA021J1 is one of Seiko's most iconic diving watches. For many people this series welcomed Seiko in the high-end diving watch world - with good reason - and this latest model pushes the bar even higher. The finishing level, the specifications and the overall feel are absolutely top notch.
To start, the movement. It's the Seiko Cal. 8L35, based on the Grand Seiko 9S55. A beautiful, 28,800bph movement with 50 hours of power reserve and specifications of +15/-10 seconds per day. A truly amazing, in-house movement that does justice to a watch in this class.
The watch itself, with its monobloc case, is very elegantly shaped, nicely fitting around your wrist. While the initial 44.3mm diameter may put you off a little bit, the placement of the crown and the relatively manageable 50mm lug to lug distance ensure it's not a goliath and will fit most wrists. The watch is purpose built, so very legible and using durable materials such as a ceramic for the bezel and a sapphire crystal to protect the dial. The bracelet also feature's a diver's extension, in case you want to wear this beauty over a wetsuit, when you take it to the 300m depth it can resist. Of course the watch also comes with an extra rubber strap included in the box.
All that aside, the level of finishing is incredible on this piece. Where you can do your best to take this watch to the limits, the watchmakers who produced this watch gave it their absolute best to make sure the smallest details are just right. There are levels to this and Seiko can compete with the best.
Seiko has proven themselves to be one of the, if not the, most versatile watch company in the world. From affordable pieces to the highest luxury via Grand Seiko and Credor. The Marinemaster is a perfect choice for anyone who is not willing to compromise on a diving watch, whether you conquer the oceans... or the office.

We're an authorised dealer of all of our brands, unless otherwise noted. In this day and age there are also many 'grey market dealers' that compromise. What are the main benefits of buying from an authorised dealer with regard to the warranty?
2 year warranty
We offer a 2 year warranty on all watches. This covers all mechanical malfunction arising from parts failure and/or assembly errors. Excluded are parts that by their nature may not last 2 years, like batteries and leather straps, damage/problems caused by improper use and wear and tear. We stand behind the brands that we sell and the quality that they offer.
Some of our brands also offer an international warranty, which will also apply.
Service and parts
In the unfortunate event of a problem with your watch, you simply need to send it to us (or take it to another dealer if the brand offers an international warranty). We have access to the official service centers, where only original parts are used and the watchmakers are qualified and experienced with your type of watch. Not every watch movement is the same, so it's best if it's handled by people who know what they are doing.
After your 2 years warranty has expired we are able to offer service in most cases.
