Want to know how the Seiko Marinemaster 300 SBDX001 is still good in 2022 then we will explore this discussion in this guide.
Seiko is known for producing quality watches at inexpensive prices. Most of their products can be easily purchased in shops and online stores, making the brand highly accessible to everyone. They offer a wide range of models for diving, sports, casual, and formal uses.
One of the crowd-favourites from Seiko is the Marinemaster 300 SBDX001. This mechanical watch is popular for its solid build and features designed for professional diving. If you’re looking for a robust diving watch to add to your collection, you must include this in your list of watches to hunt for.
History of the Seiko Marinemaster SBDX001
The Seiko Marinemaster 300 SBDX001 is more than two decades old, but it’s still a coveted model because of its incredible performance.
The Seiko Marinemaster belongs to the ‘Prospex’ collection, which is a nickname for ‘Professional Specifications’. Being part of this range means each watch is equipped with highly reliable components that can satisfy the need of professionals using it. For instance, the SBDX001 is equipped with an automatic movement and built with a high water-resistance rating for specialized diving use.
The most famous feature of the Seiko Marinemaster is the virtually indestructible monobloc case. Being a one-piece structure, the case back is incorporated with the whole watch case, so you won’t find screws at the back of the watch. The only access point to get to the insides of the watch is through the dial. This feature is a huge advantage for a dive watch that needs extra resistance against intense water pressure.
But because of the case, the Seiko Marinemaster is quite heavy on the wrist. The weight won’t matter though when you start diving with it.
Design and Movement
The Seiko Marinemaster 300 SBDX001 has a one-piece stainless steel case measuring 44mm wide and 14.6mm thick. The use of a monobloc case eliminates the need for a helium escape valve that’s seen on other diving watches.
The watch has a 120-click bezel that’s made of serrated stainless steel with a black lacquer coating. The unidirectional bezel has a luminous triangular pip at the noon position which is a standard for diving watches. It has a bit of play to make it easier to turn. Rest assured it won’t accidentally move when worn.
The Marinemaster 300 SBDX001 has a screw-down crown placed at the 4 o’clock position to prevent it from digging into your wrist. It has a coin edge for better grip.
The Marinemaster’s bracelet has a ratcheting system that makes it easy to adjust to any wrist size. The stainless steel band has a double-locking, fold-over, push-button deployant clasp similar to what other dive watches have. But in case you prefer a rubber strap, the SBDX001 comes with one for free.
The bracelet of the SBDX001 is very comfortable to wear. However, its overall finish doesn’t match the price tag of the watch. Seiko needs to up its game on this minor detail to be on par with the bracelets of watches from Swiss manufacturers.
The Marinemaster’s dial has a grainy texture and features hour markers in circular and rectangular shapes. At the 3 o’clock position, you’ll find a date window. On the outer ring, you’ll find the minute track. The text on the bottom part of the dial takes up space, but it doesn’t impede the legibility of the watch face.
The watch face is protected with Hardlex crystal that has an anti-glare coating. The crystal is the dual-curve type, giving the watch extra water resistance strength. However, it’s disappointing that at its price range, Seiko can’t afford to put in a sapphire crystal.
The Seiko Marinemaster 300 SBDX001 is powered by the 26-jewel caliber 8L35 automatic movement. It boasts a 50-hour power reserve and an accuracy of +15/-10 seconds per day. This kind of precision is what you usually expect from automatic watches manufactured by luxury brands, so this is a plus point for Seiko.
Here are some points to consider that will help you decide whether you should buy the Marinemaster SBDX001.
According to SBDX001 owners, the watch remains reliable even after a decade. It runs at an acceptable accuracy of -/+20 seconds even though it doesn’t receive regular servicing. This evidence proves the reliability and sturdiness of the watch that resonates with its price.
The Seiko Marinemaster 300 SBDX001 is priced around $2,000. The watch has polished and brushed surfaces that can be compared to more expensive models from Swiss watchmakers, so the look justifies its price. The build and features also satisfy the requirements for a professional diving watch.
Lumibrite is applied on both the hands and markers to make them glow brightly at night and underwater. The glow gives an off-white color that lasts for 3 to 5 hours, depending on how long the watch has been exposed to light beforehand. Compared to other watches that use SuperLuminova, the Lumibrite on Seiko Marinemaster stands out because of its brightness.
Is the Seiko Marinemaster 300 SBDX001 water-resistant?
The Seiko Marinemaster 300 SBDX001 has a water-resistance rating of 300 meters. This is the recommended rating for scuba diving and other intensive water sports.
How do I change the straps?
You’ll find holes in the lugs which you can use to replace the strap if you’ve got the proper tool for adjustments. The box of the Seiko Marinemaster 300 SBDX001 package comes with an extra rubber strap.
How long is the warranty for the SBDX001?
The warranty for the Seiko Marinemaster 300 SBDX001 is 2 years which is the average period given by manufacturers to their products.
Does it have a second hacking feature?
The Seiko Marinemaster 300 SBDX001 has both second hacking and manual winding features.
The SBDX001 lives up to its hype due to its top-notch movement, hardy build, high water-resistance rating, and quality components. Wearing it will give you the confidence that it can withstand almost any kind of pressure while taking little to no physical damage.
At around $2,000, the Seiko Marinemaster is quite pricey, but not as expensive as newer models that have the same build and quality. Additionally, it’s hard to find nowadays because it’s not in production anymore. You’ll rarely find one that’s been slightly used and still in pristine condition.
If you’re a collector of diver watches, you must include the Marinemaster in your stash. But if you’re on a budget, a more affordable dive watch from Seiko may be more suitable for you.
