Best Seiko SKX Alternatives – Replacements For This Very Popular Dive Watch?


If you buy through links on our site, we may earn an affiliate commission. Details

The Seiko SKX (or SKX007) is one of Seiko’s most popular watches, and often referred to as one of the most popular dive watches in the world.

The watch is considered an affordable dive watch—a great value considering its high quality and water resistance (ISO 6425 and a 200m water-resistance, which makes it qualify as a diver’s watch). Released by the Japanese brand in 1996, the watch followed the Seiko 7002, which it resembled in look and features.

It looks like Seiko has discontinued the production of the SKX (although the company has not officially announced it yet). The watch is still currently available in the secondary market, but if you’re looking for similar models, read on. Below, we’ll provide some of the best alternatives to the SKX007 (or SKX009, which has the same features, but a different bezel—blue and red, or “Pepsi” bezel).

Best Seiko SKX Alternatives (SKX007 & SKX009)

In writing this list, we took note of the main selling points of the SKX: at least 200m water resistance, around 42.5mm in diameter, and the affordable price tag (one could find a $200 SKX, but prices have increased to around $300 since Seiko stopped production)—a good deal considering the dive watch features. Not all watches below will have the exact measurements and features, but they all have close similarities with the SKX.

The Seiko Prospex SRP777

Since Seiko has many types of diver watches, the list will include a number of models by the brand. First off is the Seiko SRP777, a stainless steel automatic dive watch that has a similar look to the SKX007.

This 45mm model runs on caliber 4R36 and has features like Lumibrite on the hands and indexes, a durable Hardlex crystal, a stop second-hand function, and a unidirectional rotating bezel. This watch has a sporty silicone band and a day/date display at 3 o’clock. Like the Seiko SKX007, this model is water-resistant to 200m.

This watch is nicknamed “Turtle,” because of its cushion-shaped case. This watch continues to be praised for its value, durability, and timeless design. It was inspired by vintage Seiko dive watches—the reference 6309, which was very popular in the late 70s to the late 80s.

Then there’s the Prospex Samurai SRPB5, which does not really have the same look as the SKX but is similar to it in terms of relative affordability. The Seiko Prospex Samurai SRPB51 was inspired by the brand’s 2004 release, the Seiko Samurai (the named after the watch hands, which are shaped like swords).

This model is a bit bulkier and runs on the Seiko 4R35 movement. The watch is stainless steel and has a unidirectional bezel, screw-down offset crown, and a 41-hour power reserve.

The watch also has a checkered dial, which creates a textured look and provides a good reflection of light. The hands and markers have Lumibrite for legibility, and the red seconds hand provides a pop of color to the watch.

Seiko Prospex SLA021 (MM300)

The Seiko SLA021 is on the pricier end of the Seiko spectrum. While it does look similar to the SKX007, its features are far more superior, and so the price is also a bit steep (priced at 3100 on the Seiko website)

This watch, which is a successor of the MM300 SBDX017, has a different depth rating than the SKX007—300m, which makes it a good watch for diving and saturation diving.

Running on Seiko’s caliber 8L35, this watch has a stainless steel case and bezel, sapphire crystal, and anti-reflective crystal coating. The hands and indexed have the Lumibrite feature. One notable feature is the finish, which is done using the brand’s traditional Zaratsu polishing method that is used on the Grand Seiko line.

The Seiko Prospex SRPC35K1, which has Seiko’s caliber 4R35, is a stainless steel watch with a 200m water resistance, Hardlex crystal, and Lumibrite features on hands and indexes.

This watch is from the Seiko release usually referred to by fans as “mini turtle” watches, which are smaller than the SRP77x, the reissue of the ref. 6309 dive watches, released in the late 70s and again in 2016. The “Turtle” is 45mm, and these line of “Mini Turtle” watches, which include this SRPC35K1, is 42.3mm.

To see the comparison between the two, you can check out this review by Worn and Wound.

The SKX007 and the mini turtle watches are similar, “Close siblings” and they sell in a similar price range as teh SKX007 did when in production..
