PINDU JHLS33-1 Skull Double Flying Wheel Automatic Watch — 45.5mm

PINDU JHLS33-1 Skull Double Flying Wheel Automatic Watch — 45.5mm

The PINDU JHLS33-1 is a 45.5mm automatic watch built around two visual focal points: a three-dimensional sculpted skull and crossbone dial, and a dual open-heart flying wheel display that presents two independently rotating balance assemblies through openwork sections of the movement architecture. The combination of the 3D skull dial and the visible mechanical flying wheel movement creates a layered visual experience that alternates between the static skull sculpture and the continuously rotating wheel elements above it.

The case is 316L stainless steel at 45.5mm diameter and 23mm total thickness — a very substantial watch both in footprint and depth. Sapphire crystal (per product title and tags), silicone strap, folding buckle, 50m water resistance. Available in silver, rose gold, silver diamond bezel and rose gold diamond bezel.

Spec note: The product description states “mineral crystal” in the technical table while the product title and feature tags specify “sapphire crystal.” The page title and feature list take precedence — confirm current specification with Jewelry Addicts at time of purchase if crystal type is a deciding factor for you.

Key Specifications

Variants — Four Configurations

Silver: Polished stainless steel case with standard bezel. The most restrained of the four — the steel tone lets the skull dial and flying wheels carry the design without case colour competing for attention.

Rose gold: Warm rose gold-tone case hardware. The rose gold against the skull dial creates a warmer, slightly more ornate character than the steel. The rose gold tone pairs well with the decorative flying wheel assemblies’ warm-metal components.

Silver diamond: Polished steel case with a diamond-set bezel — small stones set around the bezel perimeter. The diamond bezel adds a deliberate luxury-contrast element to the mechanical and aggressive skull character of the watch. A specific combination for buyers who want both the aggressive dial and the gem-set bezel simultaneously.

Rose gold diamond: Rose gold hardware with diamond-set bezel — the most formally ornate of the four configurations and the maximum statement version of the design.

The 3D Skull Dial

The skull dial uses three-dimensional sculpted construction — the skull is physically raised above the dial surface as a formed element rather than printed or engraved flat. This means the skull casts shadows across its own surface under raking light, the eye sockets and teeth have genuine depth when viewed from above, and the overall impression changes depending on the angle from which the watch is viewed.

The crossbone elements visible in the dial composition contribute to the overall skull and crossbones motif. The openwork sections of the dial that frame the flying wheel displays create a layered visual field where the skull sculpture, the open dial sections and the mechanical wheel elements all sit at different physical depths — producing a dial with genuine three-dimensional complexity.

Dual Open-Heart Flying Wheel Display

The dual flying wheel display presents two balance wheel assemblies through openwork windows in the movement/dial construction. The wheels rotate continuously as the movement runs — the automatic winding maintains the movement power reserve and the balance wheels oscillate at the movement’s beat frequency throughout.

What the flying wheel display is: an open-heart complication where the balance wheel — the oscillating regulating organ of the mechanical movement — is exposed and visible rather than hidden under the movement bridges. The “flying” designation refers to the unsupported appearance of the balance wheel in its cage, which appears to float without a visible upper bearing (the upper bearing is typically on the caseback or a recessed bridge rather than prominent over the top of the wheel).

What it is not: the JHLS33-1 dual flying wheel is a decorative display complication, not a tourbillon. A genuine tourbillon rotates the entire escapement assembly in a cage to counteract positional error — a significantly more expensive mechanism. The JHLS33-1’s flying wheels are open-heart balance wheel displays providing visual mechanical interest without the tourbillon’s rotation of the full escapement. This is accurately disclosed in the product’s own FAQ: “a dual open-heart decorative flying wheel — giving a tourbillon-style look without costing thousands.”

The two wheels rotating independently create a dynamic visual display that changes constantly — one of the primary reasons buyers choose this watch.

45.5mm × 23mm — Understanding the Dimensions

At 45.5mm diameter and 23mm case thickness, the JHLS33-1 is one of the largest watches reviewed on this site. The 23mm total thickness — nearly an inch deep — is the result of the three-dimensional skull dial construction, the flying wheel assemblies above the movement, and the sapphire crystal adding to the total height.

Who this fits: wrists from 7.5 inches (19cm) upward. Below 7 inches the case will extend past the wrist edge and the 23mm thickness will make the watch sit very high above the wrist surface.

Under sleeves: a 23mm thick watch will not clear shirt or jacket cuffs. The JHLS33-1 is a watch worn over the sleeve or with pushed-up sleeves — not a cuff-clearing daily office piece. This is a design characteristic of the statement watch category, not a limitation specific to this model.

The silicone strap is the correct material choice for a 45.5mm × 23mm watch — it provides the flex and conformity to the wrist needed for comfort at this case volume, in a way that a rigid stainless bracelet would not.

Who Is the PINDU JHLS33-1 For?

The JHLS33-1 is built for buyers who specifically want:

• A 3D sculpted skull dial on a genuine automatic mechanical watch — the skull aesthetic is the primary purchase reason
• The dual flying wheel open-heart display as a continuously animated mechanical element
• Maximum wrist presence from a 45.5mm statement piece
• The diamond bezel option as a specific luxury contrast against the aggressive skull design

This watch is not for buyers who want a subtle, versatile daily wear piece or who need cuff clearance. It is a deliberate statement watch with a specific aesthetic that either matches your preference exactly or doesn’t.

How It Compares

vs. Borgiage Skull Dial Automatic — The Borgiage skull watch takes a different approach to the skull aesthetic — compare case size, dial depth and movement display architecture directly.

vs. PINDU Las Vegas Roulette Watch — The PINDU Las Vegas is PINDU’s most-viewed statement piece — casino table aesthetic rather than skull. Both are bold, large-format PINDU automatics; choose by design preference.

vs. PINDU PD6628 Black Roulette — The PD6628 uses NH35 in a black case with skeleton centre. The JHLS33-1 is the skull/flying-wheel alternative for buyers who want the PINDU mechanical aesthetic in a completely different direction.
