Seiko SKX vs. Seiko 5 Sports: Which Diver Should You Buy?
The discontinued SKX007 is a legend, but the Seiko 5 Sports replaced it. We compare movement, water resistance, value and which one to buy in 2026.
Few watches inspire as much loyalty as the Seiko SKX007. When Seiko discontinued it and rolled out the 5 Sports line in its place, the community had opinions. So which one actually deserves your money today?
The case for the SKX
The SKX007 (and its SKX009 “Pepsi” sibling) earned legend status for good reason:
- True 200m ISO dive rating with a screw-down crown.
- Iconic proportions and that unmistakable cushion case.
- A cult following that makes it endlessly moddable.
The catch: it’s discontinued, so you’re buying used or new-old-stock, often at prices that have crept well above its original retail.
The case for the 5 Sports
The modern Seiko 5 Sports SRPD line keeps the SKX silhouette but updates the internals and adds variety:
- The 4R36 movement adds hand-winding and hacking (the seconds hand stops when setting) — features the SKX’s old 7S26 lacked.
- A display caseback shows off the movement.
- Dozens of dial and bezel options across regular runs and collaborations.
The trade-off: water resistance drops to 100m and the crown is push/pull, not screw-down — so it’s a desk diver and swimmer, not a serious scuba tool.
Head to head
| SKX007 | 5 Sports (SRPD) | |
|---|---|---|
| Movement | 7S26 | 4R36 (hacks + hand-winds) |
| Water resistance | 200m ISO | 100m |
| Crown | Screw-down | Push/pull |
| Availability | Discontinued | Current |
So which should you buy?
- Buy the SKX if you want the original icon, plan to mod it, or actually dive — and you can find one at a fair price.
- Buy the 5 Sports if you want a current watch with a better movement, warranty and more style choices for everyday wear.
The bottom line
The SKX is the heritage pick; the 5 Sports is the smarter everyday buy for most people in 2026. You really can’t go wrong — both are quintessential Seiko.
