TLDR: Review of the Seiko SKX173 Dive Watch

Product Description

The Seiko SKX173 is an automatic dive watch from the famous Japanese brand under their Seiko Divers collection. 

This tool watch has similar features as the SK700X, such as the stainless steel case thickness, diameter, and movement. However, the only difference between the SKX173 from the SK700X is its dial.

SKX173’s black dial functions as a dive watch. This automatic watch may not be stylish or fashionable, but it does provide you with the features that are necessary for a diving session, such as the Cal. S726 automatic movement. Unlike other expensive watches, the SKX173 offers quite a beating.

Apart from the matte black dial, it also includes a black bezel. Minimal signatures can also be found on the dial such as the “Seiko” logo, “automatic”, and lastly, th3 “Diver’s 200 m” which symbolizes a dive watch that complies with the ISO 6425 dive watch standard.

Other features of the Seiko SKX173 include big, bulky, and luminous hands with an arrow shape, which help you read the time. 

This feature is essential for a diver to know the time spent underwater. It also comes with a stainless steel case, a rubber band, and a red-white inner chapter ring.

The dive watch’s markers are also crafted like the hands, which offer high visibility no matter what the light condition. 

The wide and rectangular markers give you enough room to fill lume. They also complement the line-markings.

Whether you’re a professional diver or somebody who simply enjoys diving for leisure, this timepiece is a great dive watch for you. 

Seiko watches feature an original LumiBrite substance, which allows the lume to glow brightly and for a long period.


Here are some of the best features of this great watch:

  • Suitable for both professional and amateur divers
  • Designed for water sports activities like scuba diving
  • Features a unidirectional bezel that rotates
  • Includes a simple, but functional black dial
  • Offers a quality Japanese Automatic Movement

Quality and Durability

One feature to admire about the Seiko SKX173 is its compact size, unlike other average automatic watches in the market today. 

Its stainless steel case diameter measures 42 millimeters, compared to most watches with the other watches that measure 44 millimeters. 

Considering that it’s a diver watch, its thickness measures 14 millimeters and gives the wearer or the diver a heaving feeling.

The SKX173 has also been around in the market since the ’90s, which makes it an old watch. 

This dive watch also includes short lugs and a 46-millimeter lug to lug distance, making it suitable for men with small to average wrist sizes. Its hardlex crystal also protects the watch from scratches. 

The stainless steel case includes sides that are highly polished while the finishing is brushed at the top of the lugs. 

Similar to the SKX007, this automatic watch offers comfortability on the wrist thanks to its rounded stainless steel case at the sides. Lastly, it features an automatic movement that has Japanese quality and a simple but functional black dial.

Additional Features

Other features to admire about the Seiko SKX173 include a date and day display. This feature is a simple but efficient factor to consider in a great watch since it pays to remember the little details and assist someone who asks what day it is. 

Seiko features a Hardlex crystal, which is their version of a mineral crystal and is scratch resistant. 

Another feature to look at is its unidirectional rotating bezel, which can be used for divers to time the elapsed dive time.

One difference between the SKX173 and the SK700X is the strap. The prior only comes with a polyurethane strap, which is a synthetic material made to mimic rubber. It also consists of ribs and a unique design, which can be beneficial for divers or any athletes. 

Another comparison between the two watches is their watch faces. The SKX173 is wide and rectangular, whereas the SKX007 has a circular blob. Not to mention, their second hand are also not similar. 

Lastly, the SKX173 offers 200-meter water resistance and is compiled to the ISO 6425 Diver’s watch standard. The screw-down stainless steel case back and crown and durable construction make this Seiko watch the perfect dive watch.
