SKX007 vs SKX009: What is the main difference?

SKX007 and SKX009, two of Seiko’s most popular entry-level diver’s watches, are very similar to one another yet differ in a few important ways. I will look into SKX007 vs SKX009 in this article and see the differences and similarities between these two models.

Seiko first introduced the SKX collection in 1996, which consists of entry-level diver watches that are powered by automatic movements. Two of the most popular references from that collection are the SKX007 and SKX009, which became a huge success and because of that success, the production of these references continued for more than 20 years.

SKX007 vs SKX009: Main difference

The color of the Dial and Bezel is the primary distinction between the SKX007 and SKX009 watches. Apart from that, both models are identical. The SKX007 has a black dial and a black bezel, which is a classic color scheme for a diver watch. The SKX009, on the other hand, has a dark blue dial and a blue/red (Pepsi) bezel, which is similar to Rolex GMT Pepsi. One thing to keep in mind is that both models have the same unidirectional bezel, despite the color pattern on the bezel being different on each model.

The hour markers are identical on both models, and the same is true of the hour and minute hands. The hour markers and minutes/hours hands on both versions have luminescent phosphorescent coatings to make it easier to read the time in the dark. Both models have the day/date function located at 3 o’clock and in some versions can be adjusted in a number of languages.



Both models share the same 42mm case diameter, which is a very common size and will fit most wrists. Due to the size of the automatic movement inside, which requires more room than quartz movements, the 13mm case thickness is slightly larger than typical. The case is made of stainless steel that is nicely brushed. There aren’t any sharp edges, hard transitions between portions or hard lines in the case’s general design. The case’s sides are beautifully polished, and the lugs’ tops have a fine-brushed appearance. Where the case and bezel meet, there is a tiny bevel that continues all the way to the lugs.
The Hardlex crystal is the feature of the SKX series that is most unique. It is essentially the mineral glass that Seiko has trademarked. Although less scratch-resistant than sapphire glass, it will be more durable than acrylic crystals. Choosing to utilize a Hardlex crystal over a Sapphire crystal reduces costs, but it’s also crucial to remember that Hardlex is less likely to break than sapphire.

A well-known feature of the SKX line, the crown is located at 4 o’clock and has large crown guards to prevent anything from catching. Another classic component of a dive watch. Essentially, both timepieces are diving watches. A well-waterproofed watch should also have a screw-down case back and crown and the SKX has both. Since they are rated to 200m, which is the minimum depth for a dive certification, you could actually use them for a fairly routine dive. Keep in mind that the rating’s number (200m) only represents the method used to conduct the test; it does not represent the depth to which you can dive.

The 120-click bezel is really carefully made. The bezel action is very flawless, and it has a two-tiered notch pattern for a secure grip. You typically get some wobbling or subpar action at this pricing bracket. This is not the case. Smooth, with reliable clicks and no obvious play. It has the same texture as the bezel of an expensive watch.

Both the Skx007 and Skx009 are powered by the 7S26 automatic movement, which was introduced to the market in 1996 and is as reliable as any other Seiko movement. It makes the watch feel quite traditional and is very dependable. The 7S26 has a quick-set day/date display, 21 jewels, a beat rate of 21,600 bph, non-hand-winding and non-hacking, and automatic bi-directional wound using Seiko’s unique Magic Lever mechanism. However, the accuracy range is fairly wide, estimated at roughly -20 to +40 seconds per day.


The SKX007/SKX009 is a remarkably customizable timepiece. It is available with a variety of straps, such as a rubber two-piece, a stainless steel oyster bracelet, and a stainless steel jubilee bracelet. I chose the rubber band because I am not a huge fan of the stainless steel bracelets Seiko utilizes with its less expensive watches. Despite being a little stiff, it wears reasonably comfortably. Since the SKX is a diving watch, it goes without saying that it would look wonderful on a NATO military slip-through strap, which is a great alternative for the summer.

Price & Availability

Seiko formally discontinued the Seiko SKX in 2019. As a result, they are more difficult to find and, even when you do, their price will be greatly inflated. You still can find them available online on a marketplace like chrono24 and ebay where the price starts around $250 USD and above
