Seagull Natural Series Polaris Automatic Watch — ST17 In-House, 40mm, 10mm, Wave Dial

Seagull Natural Series Polaris Automatic Watch — ST17 In-House, 40mm, 10mm, Wave Dial

The Seagull Natural Series Polaris is a 40mm in-house ST17 automatic dress watch with a three-dimensional wave-textured dial and a Polaris star-inspired small seconds pointer at 6 o’clock. Sapphire crystal, 316L stainless steel case at 10mm and polished stainless steel bracelet with hidden butterfly clasp, luminous hands and markers, exhibition caseback, 5 bar water resistance. Four dial variants: Lava (816.12.6180), Ocean (816.32.6180), Rock (816.52.6180) and Dune (816.72.6180).

Key Specifications

Variants — Four Dial Configurations

Lava (816.12.6180): Deep red wave dial inspired by flowing lava — layered red tones with three-dimensional texture creating strong visual depth. The most assertive and colour-rich of the four variants.

Ocean (816.32.6180): Blue wave dial inspired by coastal waters — a fresh, clean blue with the wave texture creating varying shades from deeper to lighter blue across the dial surface. The most broadly appealing configuration for everyday dress wear.

Rock (816.52.6180): Silver-grey wave dial inspired by natural stone — the most neutral and formally versatile of the four. The grey wave texture is visible as subtle directional light play without a dominant colour character. Appropriate for the widest range of formal and business contexts.

Dune (816.72.6180): Warm champagne-gold wave dial inspired by desert landscapes — the warmest and most formally classical of the four. The champagne tone on a steel bracelet creates a gold-effect palette without gold case material.

Seagull ST17 In-House Movement

The ST17 is Seagull’s in-house rectangular automatic caliber — designed and manufactured at the Tianjin Sea-Gull Watch Group facility. On the Natural Series Polaris it is fitted in a round case, which requires specific case architecture to accommodate the rectangular movement geometry within the circular case space.

At 17 jewels and 21,600 vph the ST17 is a standard-specification dress watch automatic — not a high-beat caliber but appropriate for the watch’s formal character. The ~40-hour power reserve is standard for dress automatics; the watch stops after approximately 40 hours unworn without winding. The exhibition caseback presents the ST17 movement and rotor in operation.

Wave Dial — Three-Dimensional Texture

The Natural Series dial uses a sculpted wave pattern — raised and recessed surfaces in concentric or flowing curves across the entire dial face. The three-dimensional relief creates light play that flat or printed dial textures cannot produce: as the wrist angle changes, different wave surfaces catch the ambient light, shifting the dial’s apparent colour depth from moment to moment.

The four dial variants (Lava, Ocean, Rock, Dune) use the same wave texture applied to different colour bases. The wave pattern on the Lava variant creates the most dramatic colour contrast between crests and troughs; on the Rock variant it creates the subtlest depth.

Polaris Sub-Seconds Design

The small seconds sub-dial at 6 o’clock incorporates a star-shaped Polaris pointer — the pointer is styled as a star or compass point rather than a standard sword or baton. Polaris (the North Star) is the navigational reference used across cultures to find true north — the star pointer on the sub-dial is Seagull’s design signature for the Natural Series, creating a distinct visual focal point rather than a generic seconds display.

The running seconds pointer confirms the movement is operating continuously and provides the traditional dress watch visual of a separate seconds register.

10mm at 40mm — Slim Steel Bracelet Watch

At 10mm on a 40mm case the Natural Series Polaris is among the slimmest in-house automatic steel bracelet watches available at this price. The slim profile allows the watch to clear shirt cuffs without the pronounced height of most automatics. The 126g total weight — case and bracelet — is moderate for a steel bracelet watch.

Seagull as Manufacturer

The Seagull Watch Group (Tianjin) is the movement manufacturer, not an assembler brand. The ST17 is a Seagull caliber; buying the Natural Series Polaris means buying a watch where the manufacturer made both the movement and the case. This is a distinction shared by very few brands at this price tier — most use movements purchased from Seiko, Miyota or Hangzhou.

Who Is the Seagull Natural Series Polaris For?

The Natural Series Polaris is built for:

• In-house automatic dress watch buyers who want a Seagull-manufactured movement in a slim 10mm steel bracelet at 40mm
• Wave texture dial buyers who want the three-dimensional natural landscape dial surface on an automatic dress watch
• Dune or Lava dial buyers who want the champagne-gold or deep red colourations in the wave texture format
• Steel bracelet dress watch buyers who want the bracelet included (rather than leather strap only) on a slim in-house automatic

How It Compares

vs. Seagull M160S Flywheel Legend — The M160S uses ST25 at 39mm with open-heart, day and pointer date at 13mm thickness. The Polaris uses ST17 at 40mm with small seconds only at 10mm — slimmer, simpler complications, different dial aesthetic.

vs. Farasute 5336A — The Farasute uses Hangzhou automatic at 39mm/8.95mm with radial guilloché. The Polaris uses Seagull ST17 in-house at 40mm/10mm with wave texture — in-house movement vs third-party, similar slim profile category.

vs. San Martin SN0150 MOP — The San Martin uses Miyota 9015 at 39mm/10.2mm with guilloché MOP dial. The Polaris uses Seagull ST17 at 40mm/10mm with wave texture — similar slim dress category, different movement source and dial treatment.
