00:00 Introduction
01:05 Overview
Both of these models are the "Made in Japan version". The SKX used is an SKX011J and the Seiko 5 Sports is a reference SBSA009.
Both models are available in non-JDM versions as the SKX011K and SRPD59, respectively.
02:02 Case Comparison
The cases on both of these watches are essentially the same. That is because the Seiko 5 Sports line of dive watches were based largely on the SKX. This is likely due to the significant success that the SKX had over more than 2 decades.
The dimensions of the two watch cases are the same, and both have Seiko Hardlex crystals. Yet, the Seiko 5 Sports has a sapphire case back whereas the SKX has a solid caseback.
02:16 Bezel Comparison
Both bezels are quite similar to each other, however, the SRPD59/SBSA009 only has individual minute markings from 0 to 20 whereas the SKX011 has 60 individual minute calibrations on the bezel.
02:52 Orange Dials Comparison
The orange dials are where these two Seiko divers differ a great deal if you take the time to look up close.
The SKX has a bright orange dial that has a "flat" texture. On the other hand, the Seiko 5 Sports has a similar orange dial except it has a radial, brushed sunray finish. This definitely gives the SBSA009 a more refined look.
Additionally, the SBSA009/SRPD59 has applied hour indices whereas the SKX011 has lume plots that are painted directly on the dial.
Both models have gold-coated center hands, a black seconds hands, and green Siko LumiBrite luminous.
The date window, printed minute markings, and shape of the hour indices are largely the same.
05:00 Bracelet/ Strap Comparison & Options
The SKX011 is mostly sold on a black rubber strap. The SBSA009, on the other hand, is largely offered on the steel bracelet. In this category, the new SRPD59 is much more comfortable to wear than the SKX.
07:05 Crowns & Movement Comparison
The SKX has a screw-down crown and 200m water resistance. On the other hand, the SRPD59 does not screw down so its water-resistance tops out at 100m, however, the movement can be wound through the crown.
The SKX is powered by an older Seiko 7S26 movement while the SRPD59 is powered by the newer Seiko 4R36. Both movements are automatic with a power reserve of around 41 hours, yet the newer 7S26 also boasts hand-winding and hacking seconds functionality. These two features definitely place it a notch above the SKX and the older 7S26 movement.
