00:00 Introduction & First Look On The Wrist
At a first glance on the wrist, the SBSA005 is on the larger side though it wears very comfortable nonetheless. The full steel, three-link bracelet goes a long way in balancing the watch on the wrist and making it feel very adequately sized.
01:10 Case Specifications
As measured with calipers, the case specs of the SRPD55 and SBSA005 are:
- 42.5mm in diameter
- 46mm lug-to-lug
- 13.4mm thick
- 22mm strap size (between the lugs)
The stainless steel case also boasts a high-polished finish on its case flanks and a contrasting, brushed/satin finish on the top of the case.
The bracelet and clasp likewise follow the theme of the case in that the top and bottom are brushed and the sides of the links are polished.
02:13 Brief Visual Comparison With SKX007J
03:40 Unidirectional Diver's Bezel
The steel bezel of the SRPD55K1 rotates unidirectionally and has a black metallic insert. This insert has a black background and a diver's scale in silver color. The bezel is also textured on its outside surface to provide additional grip.
This SBSA005 (and the SRPD55K1) have a scratch-resistant and shatter-proof Seiko Hardlex crystal protecting the face of the watch.
04:47 SBSA005/SRPD55 Black Dial
The dial of the Seiko 5 Sports SRPD55K! has a flat black finish and is surrounded by a slanted rehaut that is marked by printed, silver minute markings.
The dial also has applied hour indices that have a polished finish. These are filled with green Seiko LumiBrite material that can be seen to shine quite brightly in the video, even in a well-lit space.
The hands at center match the polished finish of the indices and also have a ton of lume.
06:12 Made In Japan Print On Dial
Since the model used in this review is the SBSA005, it is made in Japan and this fact is reflected by some small text under the 6 o'clock index. The SRPD55K1 would not have this printing on its dial. Nevertheless, both watches have exactly the same design and mechanical performance, the only difference is the place of manufacture.
Seiko 5 Sports watches that are made in Japan also have Japanese (Kanji date) as a secondary day language. The SRPD55K1 is very likely to have Spanish as the secondary language, with English being the primary language.
07:53 3-Link Steel Bracelet
The bracelet is composed of hollow steel links that taper down from the case to the folding clasp. The clasp is very secure and will not open without both "buttons" on the sides of the clasp being depressed.
09:35 Seiko 4R36 Movement
The Seiko SRPD55K! and SBSA005 are powered by an automatic (self-winding) Seiko 4R36 caliber. This movement has a 41-hour power reserve, hacking seconds functionality, crown-winding functionality, +45/-35 secs/day accuracy, and can be seen through the crystal caseback.
The 4R36 also has some very attractive finishing on its bridges which is hardly ever encountered in an automatic watch at this price point.
11:16 Water Resistance
Since the crown on this Seiko SRPD55K1 doesn't screw into the case, the water resistance is limited to 100m or 330ft.
