The Seiko SKX007 Diver’s Automatic was first produced by Seiko Watches in 1996, following a long line of Seiko Dive watches that started in 1965 with the 62MAS, which was rated to 150m of WR. Seiko has separate lines of dive watches, the Prospex, or professional line, and their sport/amateur line. The sports line branched off from the Prospex watches in 1975 and focused more on recreational divers with their relatively shallow depth limits than the professional divers heading to extreme depths during saturation dives. The SK007 is part of the sports line, but don’t worry Seiko has never let even their budget watches suffer from any quality issues.

The Seiko SKX007 Diver’s Automatic is a direct descendant of the 7002, which was first introduced in 1988 and favored by military personnel worldwide. It was Seiko’s best selling beater dive watch until the line was retired in 1996 replaced by the SKX series of watches utilizing 7s26 automatic movement.

The Seiko SKX007 Diver’s Automatic case crown and case-back

The 41mmx 46mm stainless steel case is smooth and flowing, with barely any hard lines or transitions. The gently curved and rounded lugs blend into the case and the prominent crown guards. The only 90 degree angles to be found are on the interior of the lugs and the inside of the crown guards. This gives the case a very organic look and feel, instead of the appearance of being something machined.

The side of the case are highly polished to a mirror finish, while the top of the lugs have a less reflective brushed finish, The transition between the two finishes is very well done, and not noticeable unless you are closely inspecting the case.

Located at the 4 o’clock position, the water-resistant, screw-down crown is extremely well protected by the large crown guards. The slightly rounded, plain end of the crown only barely extends past the end of the guards. The well-grooved portion extends out above the downward sloping guards, offering a small area to get a grip.

It definitely takes a little effort to get the crown unscrewed, but this is of course by design in order to prevent the accidental opening while diving. The operation of the crown is excellent for a watch in this price range. It threads and unthreads smoothly and evenly, with no jiggle in the crown even when fully unthreaded. After unscrewing, it provides two very positive click positions when pulled outward, for setting the day/date and time.

The crown always seems to get neglected in budget watches, with many feeling poorly machined and difficult to use, but that is not the case here. A simple two-tiered grooving on the crown to match the pattern on the bezel would have upped the appearance of the watch by just a small, but the important amount.

The screw-down, rounded case-back rises significantly above the back of the case, reaching slightly taller than the ends of the curved lugs. It features a lovely engraving of a tsunami wave, which only appears now on Seiko’s ISO rated divers that have at least 200m of water resistance.

The Seiko SKX007 Diver’s Automatic crystal

The flat, recessed crystal on the SKX007 is made out of Hardlex Seiko’s proprietary hardened mineral crystal. Its resistance to scratches is greater than regular mineral crystals but less than sapphire. However, it also won’t shatter if impacted directly like a sapphire crystal would do. The crystal is slightly chamfered around the edge directly next to the bezel.

The Seiko SKX007 Diver’s Automatic bezel

The 120-click, unidirectional rotating timing bezel is constructed out of stainless steel with a black aluminum insert containing the timing markings. Every minute is marked, with long bars marking the 5-minutes, numerals for the 10-minutes, and small circles for the rest.

A two-tiered groove is engraved into the outer edge, providing excellent grip on the bezel, even when wearing thick neoprene diving gloves. The bezel turns with a quite and smooth click action, with very little wobble once set into the desired position, which still allows you to estimate rather closely what time the minute hand is currently pointing to. The bezel on Seiko SKX007 Automatic is a real pleasure to use, just stiff enough to prevent accidental adjustment but still easily operable.

The Seiko SKX007 Diver’s Automatic dial

The dial on Seiko SKX007 Automatic is minimalistic, a lume-filled triangle marks the 12 o’clock position, with large circles marking every 5 minutes. Larger ovals mark the 6 and 9 o’clock positions. The white dial/date window is located at 3 o’clock, with its size mirroring the oval at 9, maintaining the symmetry of the face. On this version of the SKX, the day can be set to show in English or Spanish. All of the text is in black, except for SAT in blue and SUN in red. The date cycles through from 1-31, so during shorter months you will have to move it ahead.

The Seiko SKX007 Automatic appears centered above the hands and directly below the 12 o’clock triangle. Centered above the 6 o’clock oval in red text is printed “Diver’s 200m” indicating that the watch is certified ISO Diver.

At the very bottom of the dial just above the chapter ring “7S26-002R R 2” is written in plain white text. This signifies the automatic movement being used in the Seiko SKX007 Automatic. The sloping chapter ring surrounds the dial, marking every minute with long bars. Every 5 minutes is marked with a slightly thicker bar. The chapter ring is well done, adding depth and a high-quality look to the face of the watch. Overall, the face of the watch is quite good looking, if simplistic. It is definitely designed more for use as a dive instrument than as jewelry, but this, of course, gives it its own charm than many people enjoy in their watches.

The Seiko SKX007 Diver’s Automatic hands

The shorter sword-shaped hour hand reaches just to the inner edge of the long oval markers, with the long narrow minute hand extending to the outer edge of the smaller circle markers. Both hands are outlined in chrome and deeply filled with luminescent paint.

The seconds-hand is long, narrow, and white, counterbalanced by a black shaft featuring a lumed lollipop. This design is somewhat unique to the SKX, as it’s more usual to have the lumed portion on the main side of the hand. The purpose of the lumed lollipop is not really to inform you of what second it is but to allow the wearer to quickly check that the watch is still running in the dark.

The Seiko SKX007 Diver’s Automatic movement

The Seiko SKX007 Automatic is powered by Seiko’s caliber 7s26, a lower-end budget, mechanical automatic movement. It features 21 jewels and runs at 21,600 beats per hour. It’s  wound by Seiko’s patented Magic Lever system, with a bi-directional winding mechanism powered by the movement of the wearer’s wrist. When fully wound, the power reserve is up to 48 hours. It lacks several features that you’ see in higher-end movement, such as hacking seconds and the ability to hand wind.

The Seiko SKX007 Automatic movement’s accuracy also suffers, with anywhere from 20 seconds slow to 40 seconds fast per day being usual when received. However, this seems to be highly variable, with several people reporting that theirs runs at an impressive +5sday. For anyone that would enjoy more accuracy, a watch-maker can allow regulating the movement which will result in drastic improvements.

The Seiko SKX007 Diver’s Automatic straps

The Seiko SKX007 Automatic comes with a stainless bracelet, however, you can easily change to either rubber or NATO strap if you prefer. Changing the watch strap can drastically change the look of your Seiko SKX007 Automatic, for instance, rubber is a much better choice if you are out in the water most of the time, and leather if you are going to attend a formal event, or NATO to spice up your Seiko SKX007 Automatic during summer season.

Changing the straps can be done on your own, however, the chances of scratching or otherwise messing up the watch are quite high, if you are not used to changing straps on your watches, let a watch-maker or shop do the work for you.
