Luminous
At 11mm, this is the slimmest watch in the Aorawa range. At 140g on steel, it is also the most substantial.
The Star Skeleton uses a round case — a deliberate departure from the tonneau models in the Aorawa range. Where the tonneau case communicates edge and individuality, the round case communicates refinement. The 40mm diameter is precise — large enough for wrist presence, small enough for classic proportions. At 11mm thickness, it slides under any dress shirt cuff without discussion.
The star-bridge skeleton dial — available in green, blue, or black — exposes the JX-2804 automatic movement with luminous markers that glow green in any low-light condition. Day legibility through the open skeleton. Night legibility through the luminous system. Six configurations from steel bracelet to silicone strap. Why skeleton watches work for professional men in 2026 →
LUMINOUS — READABLE IN ANY LIGHT
The green luminous markers on the hour indices and hands charge in seconds under any light source — natural daylight, office fluorescence, smartphone screen. In darkness, the watch glows with precision-readable intensity for hours.
Green Lume · All 6 Color Variants · Charges in Seconds
SIX COLORS — STEEL & SILICONE
Steel Bracelet Variants — Butterfly Clasp
JC9204G5SGS
Silver Case · Green Dial · Steel Band
The most refined configuration. Silver brushed stainless steel case and bracelet. Green skeleton dial with luminous markers. The combination references luxury sports watch aesthetics — green dials on steel bracelets are the most sought-after collector configuration of the decade.
JC9204G5SUS
Silver Case · Blue Dial · Steel Band
Blue skeleton dial on silver steel. The blue dial references professional sport watch culture — the colour of precision instruments and ocean depth. On a steel bracelet with luminous indices, it reads as a serious tool watch in skeleton format.
JC9204G5SKS
Silver Case · Black Dial · Steel Band
Black skeleton dial on silver steel. The most versatile configuration — the contrast between the silver case and black open movement reads cleanly across every context from office to evening. The luminous markers are most visible against the dark background.
Silicone Strap Variants — Sport & Active Wear
JC9204G5SGG
Silver Case · Green Dial · Green Silicone
Green tone-on-tone — dial and strap in matching green. The sport version of the green steel configuration. Lighter on the wrist than the steel bracelet. Best for active daily wear where the colour statement is the priority over the bracelet weight.
JC9204G5SUU
Silver Case · Blue Dial · Blue Silicone
Blue tone-on-tone. The sport version of the blue steel configuration. Full blue visual system — the luminous markers create a counterpoint in green against the all-blue colour field in low light.
JC9204G5KKK
Black Case · Black Dial · Black Silicone
All black. The most striking luminous effect in the range — the green luminous markers emerge from complete darkness with maximum contrast. In low light, this watch becomes a green luminous skeleton. The stealth configuration for men who want the watch to disappear in daylight and emerge at night.
WHY THIS WATCH STANDS OUT
⭐ Star-Bridge Skeleton Dial
A five-pointed star bridge structure radiates from the dial centre, creating five visual zones across the open movement. The star framework gives the skeleton dial geometry and balance — the most architecturally refined dial in the Aorawa range.
🌙 Green Luminous System
Hour indices and hands coated with green Super-LumiNova equivalent — charges under any light source, glows for hours in darkness. The green lume creates a distinctive night-watch character that is visible across the room in low light. All six color configurations include the luminous system.
⚙️ JX-2804 Automatic — Self-Winding
Genuine automatic tourbillon-style movement. Self-winding from wrist motion. No battery — ever. The JX-2804 is specifically designed for round-case skeleton architecture — visible through the star-bridge dial with the balance wheel and gear train running in open display.
📏 11mm — The Slimmest Profile
At 11mm thickness, this is the slimmest watch in the Aorawa range. It slides under a dress shirt cuff or a jacket sleeve without creating the visible ridge that thicker watches produce. The slim profile is the defining advantage of a round-case dress watch.
🔗 Steel Bracelet or Silicone
Three variants use a stainless steel bracelet with butterfly clasp (140g total) — the most formal and substantial option. Three variants use matched silicone straps for active daily wear. Both strap types use the same 26×20mm lug width — standard for third-party swaps.
💧 3ATM Water Resistant
Rain, handwashing, splash — covered across all six color configurations. The 3ATM rating handles professional daily wear and active casual contexts without risk to the movement or luminous system.

POLISHED DUAL-PROCESS FINISH
The Star Skeleton case uses a combination of brushed and polished surfaces — the same dual-process technique used in luxury watchmaking. The brushed surfaces diffuse light, creating a matte depth. The polished edges catch and reflect light sharply.
The transition between brushed and polished surfaces — where one finish ends and the other begins — is where quality reveals itself. On this case, the line is defined. The effect: a case that looks more complex and more expensive than its price reflects.

Night: the luminous system takes over.
Two watches. One case."

FREQUENTLY ASKED QUESTIONS
Is this a real automatic watch?
Yes. The Star Skeleton uses a genuine JX-2804 automatic self-winding movement — no battery required, ever. The seconds hand sweeps continuously. The gear train and balance wheel run visibly through the star-bridge dial across all six color configurations. Automatic vs quartz — full comparison →
How long does the luminous glow last?
The green luminous system charges in seconds under any light source — including indoor lighting and smartphone screens. After a normal day's light exposure, the lume glows brightly for 2–3 hours in complete darkness, then continues dimly for several more hours. Maximum brightness is achieved after direct sunlight exposure for 30 seconds.
Which color should I choose?
Green/Steel (SGS): The luxury sports reference — green dial on steel is the most refined and collector-appreciated combination. Blue/Steel (SUS): Professional versatility — blue reads as precision and depth, appropriate across business and casual. Black/Steel (SKS): Maximum luminous contrast — the green lume is most visible against the black dial. Green/Silicone (SGG): Active daily wear, color statement. Blue/Silicone (SUU): Sport with premium color. Full Black/Silicone (KKK): Stealth daily wear with dramatic luminous night presence.
Is the steel bracelet heavy?
At 140g total for the steel bracelet variants, the Star Skeleton is the heaviest watch in the Aorawa range — but this weight is distributed evenly across the case and bracelet. Many wearers prefer a heavier steel bracelet for the premium presence it creates. If you prefer lighter wear, choose a silicone strap variant — the same case and movement, significantly lighter on the wrist.
Is 40mm too small?
40mm is a classic round watch diameter — proportionate across most wrist sizes from 160mm circumference upward. The 50mm lug-to-lug length is moderate. At 11mm thickness, the case sits low on the wrist without visual bulk. Wearers who prefer larger watches should consider the 42×55mm tonneau models in the Aorawa range, which create stronger wrist presence.
Is this a good gift?
Yes — the six color options make personalisation straightforward. The green dial on steel is the strongest gift choice for men who appreciate watch culture; the luminous green skeleton creates an immediate impression when the watch is revealed. Arrives in gift-ready packaging with 2-year warranty and 30-day returns. Best watch gifts for him →
How does this differ from the tonneau models?
The Star Skeleton uses a round case (40mm) at 11mm thickness — slimmer and more classically proportioned than the tonneau models. It reads as a refined sports watch or dress watch rather than a statement piece. The tonneau models (42×55mm) have stronger wrist presence and more distinctive case shapes. The Star Skeleton is the choice for wearers who want a skeleton movement in a watch that reads as a conventional timepiece from a distance — but reveals something extraordinary up close.
