Why was the Seiko SKX discontinued?

Seiko discontinued the SKX007/SKX009 line around 2019 and redirected the segment into the 5 Sports series. The SKX's combination of a screw-down crown, 200m ISO-rated water resistance, and low price hasn't been directly replaced by Seiko itself — which is why buyers look sideways.

What is the best modern replacement for the Seiko SKX007?

The Orient Kamasu is the most-recommended replacement: it adds a sapphire crystal and an in-house automatic movement while keeping the 200m water resistance and screw-down crown, usually at a similar price. The Seiko 5 Sports is Seiko's own successor but loses the screw-down crown and 200m rating.

Is there a cheaper alternative to the SKX?

Yes — the Casio MDV106 'Duro' delivers 200m water resistance, a screw-down crown and a unidirectional bezel for well under $100, making it the budget answer to the SKX brief.

Seiko SKX Alternatives: What Actually Replaced the Discontinued SKX007

The short answer

Seiko discontinued the SKX around 2019 and never directly replaced it. The watches enthusiasts actually buy instead, from the roundups we track (live 2026):

Orient Kamasu — the #1 pick. Sapphire crystal + in-house automatic + 200m + screw-down crown, at roughly SKX money. The upgrade the SKX never got.
Seiko 5 Sports (SRPD) — Seiko's own successor. Same look, but display caseback, 100m, no screw-down crown — a lifestyle watch, not an ISO diver.
Citizen Promaster Diver — 200m, screw-down crown, ISO-compliant. The "screams tool watch" pick, and available in Eco-Drive (no winding) or automatic.
Tissot Seastar 1000 — the step-up: Swiss automatic, 300m, 80-hour power reserve.
Casio MDV106 "Duro" — the budget answer: 200m, screw-down crown, unidirectional bezel, usually under $100.

Why the SKX is hard to replace

The SKX was special because of what it combined at its price: a screw-down crown, a

200m ISO-rated case (true dive certification, not just a water-resistance number), Seiko's day-date, and legendary lume — for well under $300. Most "affordable divers" drop one of those (usually the screw-down crown or the ISO rating). The list above is really a list of which compromise you're willing to make.

The picks, compared

Watch	Movement	Water resist.	Screw-down crown	Rough price	The trade
Orient Kamasu	In-house automatic	200m	Yes	~SKX money	None, really — this is the upgrade path
Seiko 5 Sports	Seiko automatic	100m	No	Similar	Loses ISO diver credentials for style/variety
Citizen Promaster	Eco-Drive / auto	200m	Yes	Similar–higher	Eco-Drive means no winding, but no mechanical charm
Tissot Seastar 1000	Swiss automatic	300m	Yes	Higher	Costs more; a genuine step up in finishing
Casio MDV106 "Duro"	Quartz	200m	Yes	Under $100	Quartz, resin-era finishing — but unkillable value

How to choose

You want what the SKX should have become: Orient Kamasu. Sapphire + in-house movement, same brief, better execution.
*You want the SKX look and don't dive:* Seiko 5 Sports. Accept the 100m / no screw-down.
You never want to wind or service a movement: Citizen Promaster Eco-Drive.
You have more to spend and want Swiss: Tissot Seastar 1000.
You want a beater for $80: Casio Duro. Buy two.
