PINDU Black Roulette Watch — NH35, Skeleton Centre Dial, Push-Button Spin, 46mm

The PINDU PD6628 is a 46mm NH35 automatic watch in a black-coated stainless steel case with a multi-layered skeleton centre dial and a push-button activated spinning roulette outer ring. It is the darker, more technical version of the PINDU roulette concept — where the gold variants lead with warmth and boldness, the PD6628 leads with mechanical depth and restraint.

The centre dial uses a skeleton-style multi-layer construction — visible movement elements and layered dial components at different depths — with green gemstone-style hour markers providing the primary contrast. The outer ring carries the roulette wheel layout in red, black and green numbered segments, activated by a push-button on the left side of the case that spins the ring mechanically.

Available in black case with black or green leather strap, plus brown, red diamond, silver shell and mesh strap variants.

Key Specifications

Variants

Black case / black leather strap: The most restrained configuration. Black case, black strap, skeleton centre with green markers — the green gemstone hour markers provide the only significant colour accent. Maximum visual cohesion between case and strap, minimal flash.

Black case / green leather strap: The same black case with a deep green leather strap — the green strap picks up the green markers and the green segment of the roulette outer ring, creating a deliberate three-point green accent across strap, markers and bezel. More expressive than the all-black configuration.

Brown / red diamond / silver shell variants: Alternative dial and case tone configurations on the same platform and mechanism. Brown shifts the palette warm; red diamond introduces a faceted dial surface; silver shell removes the black coating for a bright steel finish.

Mesh strap variants: Steel mesh bracelet in place of leather — the most formal and structurally present configuration.

Black DLC Case

The black-coated case uses a PVD or DLC surface treatment over the stainless steel construction. The matte finish produces minimal reflection — where the gold PINDU variants are intentionally eye-catching, the black case is intentionally low-reflection and technical in character. The black coating is consistent across case, crown, pushers and case sides.

At 46mm diameter and 16mm total thickness, the PD6628 is a substantial wrist presence regardless of case colour. The black finish does reduce the visual size perception slightly compared to a bright steel case of identical dimensions — the absence of reflective highlights makes the case edges less immediately prominent.

Skeleton Centre Dial

The centre dial uses a multi-layer skeleton-style construction — rather than a solid flat dial plate, the centre display is built at multiple physical depths with open-worked elements between layers. This creates visual depth on the main time display that a standard flat dial cannot replicate.

The green gemstone-style hour markers — applied raised elements with a faceted green appearance — sit above the skeleton dial layers, providing clear time reading against the multi-level dark background. In ambient light the green markers catch and refract light; in low light the luminous coating provides readable glow.

This is the primary visual distinction between the PD6628 and the PD6663 wood-texture variants. The PD6663 uses a textured but fundamentally flat dial surface; the PD6628 uses genuine multi-layer depth at the centre.

Push-Button Roulette Mechanism

The push-button on the left side of the case activates the outer ring spin — the same mechanism as the PD6663. Pressing the button releases the ring to spin freely before settling at a random position. The outer ring carries alternating red and black numbered segments with a green section and a small ball indicator detail near the inner edge of the ring — a visual reference to the roulette ball that settles into a number pocket.

The time display at the centre functions normally and independently from the outer ring position. The roulette mechanism is an interactive novelty layer on top of a functional automatic watch.

PD6628 vs PD6663 — Choosing Between Them

Both watches use the same case dimensions, NH35 movement, push-button roulette mechanism and sapphire crystal. The difference is entirely in the dial and case finish:

PD6628 (this watch): Black-coated case, skeleton multi-layer centre dial, green gemstone markers. Darker, more technical character. Better suited to buyers who want the roulette concept without the overt gold-and-colour boldness.

PD6663: Polished rose-gold or steel case, wood-texture flat dial in blue/green/brown, no skeleton construction. Warmer, more expressive character. Better suited to buyers drawn to the wood-texture contrast or the gold-tone configurations.

Both are valid depending on aesthetic preference — there is no specification difference between them.

Who Is the PD6628 For?

The PD6628 is the correct choice for:

• Buyers who want the push-button roulette spin mechanism in a darker, less overtly bold presentation than the gold variants
• Those who prefer skeleton-style dial construction as a specific aesthetic — the multi-layer centre reads as more technically watch-oriented than a flat wood-texture dial
• Green accent buyers who want the green markers / green strap / green roulette segment combination as a deliberate three-point colour accent
• Gift buyers who want the interactive roulette mechanism in a case that works in more understated contexts

Size note: 46mm at 16mm thick is a very large watch. Measure wrist circumference before ordering — recommended from 7 inches (18cm) upward for proportional fit.

How It Compares

vs. PINDU PD6663 (wood-texture variants) — The PD6663 is the warm-tone, wood-texture alternative on the same mechanism. Same push-button spin, different aesthetic.

vs. PINDU Las Vegas — The PINDU Las Vegas has the casino table layout without the spinning mechanism. Different design approach — static table aesthetic vs interactive spinning ring.

vs. Richard Roulette V2 — The Richard Roulette V2 is the most-searched roulette watch at Jewelry Addicts. Compare directly for mechanism design and case architecture.

vs. Jacob PINDU Casino Watch — The Jacob PINDU is the most luxury-positioned PINDU model — more formal, less interactive.
