SEIKO SKX023 vs SKX031 Comparison

Design & Aesthetics

At a glance, the SKX023 and SKX031 may appear strikingly similar, with their iconic round cases and pronounced bezels. Yet, subtle differences set them apart. The 38mm SKX023 boasts a slightly more compact profile, often preferred by those with slender wrists. Conversely, the 40mm SKX031, with its marginally larger dial and bold indices, has an imposing presence, suitable for those who favor statement pieces.

Both models flaunt a unidirectional rotating bezel, but their markings differ subtly. The SKX031’s bezel has more pronounced minute markings, making it slightly more legible during underwater excursions.

Movement & Functionality

Ticking inside both these marvels is Seiko’s 7S26 automatic movement with 43 hours of power reserve. Known for its accuracy and longevity, it ensures that wearers always remain on time, whether they’re on land or 100 meters underwater.

Comfort & Wearability

Comfort is paramount when it comes to watches, and both models shine in this domain. Their stainless-steel bracelets, combined with the ergonomic case design, ensure a snug fit. However, the SKX023, with its slightly slimmer profile, offers a tad more comfort for extended wear.

Pricing & Value

In their heyday, both models were lauded for offering unparalleled value. Though they’ve since been discontinued, their legacy persists in the secondary market. The SKX031, given its slightly enhanced features, generally commands a higher price. However, the SKX023, with its compact charm, isn’t far behind in terms of demand.

You can but the Seiko SKX023 dive watch for around $170 and the Seiko SKX031 dive watch for around $240 from online retail shops.

Popularity & Collectability

Over the years, the allure of these models has only grown. Their classic design, coupled with Seiko’s reputation, has made them sought-after pieces for collectors. While the SKX031 often garners attention for its bold aesthetics, the SKX023 has a dedicated fan base that appreciates its subtle elegance.
