Sugess Ocean Star S450-2 Automatic Dive Watch – 40mm NH35 Movement

Sugess Ocean Star S450-2 Automatic Diver Watch — NH35A, 40mm, Ceramic or Steel Bezel

The Sugess Ocean Star S450-2 is a 40mm NH35A automatic diver with a bidirectional 36-click bezel available in ceramic or stainless steel variants, sapphire crystal with blue AR coating, sunburst dial, cyclops date magnifier and 100m water resistance on a solid 316L stainless steel bracelet. Available in six configurations across white, dark grey and blue dials on ceramic and steel bezel options.

Key Specifications

Variants — Six Configurations

White dial / stainless steel bezel: A white or cream sunburst dial on silver hardware with steel bezel — the highest-contrast configuration. The brushed metallic steel bezel creates a classic sport-dress combination appropriate for office and business-casual contexts.

Dark grey dial / stainless steel bezel: A dark grey sunburst on silver steel bezel — the most restrained bracelet configuration.

Blue dial / stainless steel bezel: A blue gradient or sunburst dial on steel bezel — the most broadly appealing classic diver combination. Blue and steel is the standard professional sport watch pairing.

Dark grey dial / ceramic bezel: Dark grey dial with the premium ceramic bezel — the combination most consistent with contemporary tool watch design. The ceramic’s scratch resistance is most practically relevant in daily use.

Blue dial / ceramic bezel: The most collected configuration — blue sunburst dial with ceramic bezel on steel bracelet. The ceramic adds a visual depth to the bezel insert not present on the steel version.

White dial / ceramic bezel: White dial with the ceramic bezel — the most formally clean combination with ceramic specification.

Bidirectional Bezel — Not Unidirectional

The S450-2 bezel rotates in both directions — this is a design choice worth noting explicitly. Most diver bezels are unidirectional (counterclockwise only) as a safety specification: on a dive watch, accidental bezel displacement can only indicate less elapsed time than actual, preventing the diver from believing they have more air remaining than they do.

The S450-2’s bidirectional bezel with 36-click resolution is a design and functionality decision rather than a dive safety instrument specification. The 36-click resolution is finer than the standard 60-click (one minute per click), providing 10-second elapsed time increments per click. For timing purposes above water the bidirectional bezel is practical. For scuba diving applications, the unidirectional single-direction safety specification is absent.

Sapphire with Blue AR Coating

The sapphire crystal carries an anti-reflective coating with a blue tint — a specific coating formulation that gives the crystal a subtle blue sheen when viewed from certain angles. The blue tint is the visual signature of the blue AR coating and is visible as a faint blue-purple iridescence on the crystal surface at oblique angles. Under direct viewing the crystal reads as clear. The AR coating itself reduces reflective glare and improves dial visibility in bright light.

Sunburst Dial

The sunburst finish — fine radial polishing lines from the dial centre — creates a shifting light interaction as the viewing angle changes. On the blue variant the sunburst transitions from a bright mid-blue at the dial centre toward a deeper navy at the edges, consistent with a deep-water gradient reference. On the white and grey variants the sunburst creates a more subtle brightness shift.

Cyclops Date Magnifier

The sapphire crystal carries a cyclops lens at 3 o’clock — a convex dome that magnifies the date approximately 2.5x. Makes the date immediately readable at a glance without moving the watch closer to the eye — a practical detail on a daily wear watch.

NH35A Movement

The NH35A is a Seiko-manufactured automatic. 24 jewels, 21,600 vph, hacking and hand-winding, 41-hour power reserve, date display at 3 o’clock. One of the most globally serviceable automatic movements available. The exhibition caseback presents the rotor and Sugess engraving from the rear.

Who Is the Sugess Ocean Star S450-2 For?

The S450-2 is built for:

• NH35A buyers who want the Seiko-manufactured caliber in a 40mm diver with ceramic bezel option
• Blue AR sapphire crystal preference buyers — the blue-tinted AR coating is a specific visual signature not found on standard sapphire
• Buyers choosing between ceramic and steel bezel on the same case and dial — the S450-2 offers both on the same model
• 36-click fine-resolution bezel buyers who want 10-second elapsed time increments

How It Compares

vs. Pagani Design PD-1661 — The PD-1661 is 40mm at 100m with NH35 or Miyota 8215 choice. The S450-2 is NH35A only with the bidirectional ceramic/steel bezel option and blue AR crystal. Different bezel architecture — PD-1661 unidirectional, S450-2 bidirectional.

vs. Phylida SE-11 — The SE-11 is 41mm at 200m with 120-click unidirectional ceramic bezel. The S450-2 is 40mm at 100m with 36-click bidirectional bezel option. The SE-11 is the higher water resistance unidirectional option; the S450-2 is the 100m bidirectional option.

vs. Baltany S203043 39mm Diver — The S203043 is 39mm at 200m with 120-click bezel. The S450-2 is 40mm at 100m with the blue AR crystal and bidirectional bezel. Different water resistance tier and bezel function.
