The stainless steel material is used for the bezel construction. Its surface is a polished and crinkled shape for a comfortable grip for movement. It is a unidirectional bezel used in both watches. Both dive watches’ bezel has the most appealing quality: its paint, which can glow in the dark. Also, markers on the bezel glow in the dark so that divers can easily monitor their time lap during underwater dive.

The most important thing for divers is that you can rotate the bezel in only one direction. So these watch bezels are unidirectional that helps the divers to notice accurate time-lapse. Bezels have grooves on the rim’s outer side that enhance your grip when you are in slippery conditions. On the face of the bezel, markings are in very highlighted form. Seconds/ minutes are shown in dots, and a thicker dash is at the 5th second/minute position. There are Arabic numerals punched at the 10th second/minutes.

There is a different option available for the different color schemes of the bezels.

Stainless steel material

The reason that makes both watches look attractive is their material and finishing. Generally, stainless steel material used for the construction of both Watches brushed for the finish. And, polished at the edges of the watch. When you look at the bezel, that adequately fits the case, making it look more efficient. For all dive watches, Seiko used this material to enhance their durability. The case’s backside is also made from stainless steel and is fitted with the screws that make it waterproof. Their back is also equipped with the technology “Seiko Tsunami” insignia; it symbolizes the best quality of water-resistance watches.

If we compare the Seiko turtle vs skx bracelets of both watches, there is some difference. It comes with a range of 38mm to 46mm lengths.

Window crystal

Like in all other Seiko watches, Seiko manufacturers use Hardlex crystal to construct the windows of both watches. Hardlex crystal is Seiko’s trademark for their watches. Here, to be honest, we will not say, this is the best material type that is available for dive watches.

Many users expect better material for window crystals. However, the watch has many other features to say the price is quite fair. On the other hand, the Hardlex crystal is durable and resistant to force.

The complaints and cons of the Hardlex crystal is easy scratching. Moreover, this material also smudges easily, which is a complaint from many buyers. Last but not least, the window crystals have a matte look. Both glasses join the bezel at an angle and look stylish.

Dive readiness

As we say, both the watches are dive watches as the watches met with the standards of ISO 6425. Dive watches must possess some standards.

  1. Water-resistance features 

Both the watches are water resistive until 200 meters.

  1. Case

The second most important is the back of the case. A dive watch must have screw-down cases from prevention of water. Here Seiko turtle vs skx both owns this feature.

  1. Easy-grip

A dive watch must have a comfortable grip on the sides of the watch. Both watches have this feature also.

  1. Bezels

The marking and hands should be luminescent, and bezels should be read easily. While having this feature, we can say both the Seiko turtle and Seiko skx are dive-ready.


The case is always important to consider to know about the quality of a watch. First of all, the case material of both watches is stainless steel. Both the lines have different ranges of sizes for each watch model.

However, the case diameter of Seiko turtles is larger than skx. For instance, the smallest diameter watch you can buy in Seiko skx is 38mm. On the contrary, you will always find large diameter watches like 45 mm in Seiko turtle. The main reason for the significant cases is the watches are specifically designed for professional use.

But if you are looking for a large diameter watch in skx, you may need to pick Seiko skx009 with a 46 mm case diameter. But here I must say, if you are not fond of large watches then none of the watches is for you. However, if you want high-quality watches, then you are in the right place here.


In bands, you have options to choose from silicon bands and stainless steel bands.

The closure type is safety clasps with stainless steel bands. On the other hand, the closure type of silicon band is the regular clasp.

However, here we will give you recommendations of silicon bands if you especially purchase watches for diving. The reason is the rubber material is super easy to maintain and clean.
