HANBORO 985 Supercar Series Automatic Watch – Double Flywheel, Luminous Numbers, 50M

HANBORO 985 Supercar Series Automatic Watch – Double Flywheel, Luminous Numbers, 50M

The HANBORO 985 Supercar Series is a large tonneau-shaped skeleton automatic watch with a motorsport-inspired design — double flywheel display, visible gear architecture, bold luminous Arabic numbers with red outlines, and a tire-pattern textured silicone strap. Hollow-out dual flying wheel mechanical movement, 21,600 vph, 21 gemstone bearings, approximately 60-hour power reserve. Stainless steel three-layer case with brushed finishing and a pull-handle crown. Crystal glass mirror. Stainless steel butterfly clasp. 44×50mm case, 16–17mm thick, 140g, 50M water resistance. Available in six colour variants (985-1 through 985-6).

Key Specifications

Double Flywheel Skeleton Dial

The 985 carries two visible hollow flywheel sections near the lower portion of the dial — a double mechanical display similar in concept to the HANBORO 851, giving the watch two points of visible oscillating motion rather than one. The remaining dial space is open skeleton architecture, showing gears and movement bridges through the front of the watch. Large raised Arabic hour numbers with red outlining sit over this open base, keeping the time legible despite the dial’s mechanical density.

Movement — 21 Jewels, 60-Hour Power Reserve

The 985 runs a hollow-out dual flying wheel mechanical movement — 21,600 vph, 21 gemstone bearings (jewels), and approximately 60-hour power reserve from full wind. This is a notably high power reserve, ahead of the 40–42 hour range typical of NH35/NH36 and Miyota 8-series movements elsewhere in the HANBORO range — a fully wound 985 will continue running through a full unworn weekend and resume accurately afterward. No specific caliber name or movement manufacturer brand is provided by the supplier; as with any automatic watch, the movement self-winds through wrist motion and can be manually wound via the crown if it stops.

Case and Pull-Handle Crown

The case uses a three-layer stainless steel construction with a broad tonneau (square/barrel) profile, combining brushed surfaces with polished cut-out sections for visual depth. At 44×50mm and roughly 16–17mm thick, this is one of the largest cases in the HANBORO range, giving it substantial wrist presence. The side crown uses a pull-handle design with a stainless steel head — a deliberate motorsport styling cue that reinforces the supercar theme alongside the brushed case finish.

Crystal Glass Mirror

The front crystal is described as a “diamond-knife crafted crystal glass mirror,” intended for clear viewing and scratch/wear resistance. This terminology does not specify sapphire — treat it as a crystal glass material with claimed wear resistance rather than confirmed sapphire-grade hardness unless the supplier provides further confirmation.

Tire-Pattern Silicone Strap

The black silicone strap carries a tire-tread style line pattern, directly reinforcing the supercar and motorsport design theme. Strap dimensions are 24×20mm with a 19cm length. The stainless steel double-press butterfly clasp provides a secure folding closure.

50M Water Resistance

Rated 50M / 5ATM — suitable for splash exposure, rain, handwashing, cold bathing, and swimming. Not rated for snorkelling or diving. The “deep waterproof” phrasing sometimes used in marketing for this listing is not a confirmed additional rating beyond 50M — treat the 50M/5ATM figure as the operative spec.

How the 985 Compares to Other HANBORO Models

The 985 shares its double flywheel concept with the HANBORO 851, but in a larger tonneau case with a sport silicone strap rather than leather. For a confirmed, independently documented Japanese movement, see the HANBORO 937 Tonneau — genuine Miyota 82S7 with a factory open-heart balance wheel window. For the leather-strap double flywheel alternative, see the HANBORO 851 Double Flywheel — Shanghai JH515 movement, crystal bezel. For a honeycomb-themed skeleton with calendar and 24-hour sub-dials, see the HANBORO King Bee Series 2003. For an interactive feature, see the HANBORO Roulette Automatic Watch — Miyota 8215 with a pusher-activated spinning wheel. For a dress watch theme, see the HANBORO Sailing Series.

FAQ

What movement does the 985 use? The supplier describes it only as an “original dual-flywheel mechanical movement” — no specific caliber name, jewel count, or power reserve figure is currently documented. If movement provenance is important to your decision, contact the seller for these details before purchase.

What is the double flywheel display? Two separate hollow flywheel sections visible near the lower dial, both showing oscillating mechanical motion as the watch runs — a more elaborate visual effect than a single balance wheel display.

Is the crystal sapphire? Not confirmed. The supplier describes a “diamond-knife crafted crystal glass mirror” without specifying sapphire-grade hardness. Treat it as a standard crystal glass with claimed wear resistance.

Is it waterproof for swimming? Yes — rated 50M / 5ATM, suitable for cold bathing and swimming. Not rated for snorkelling or diving.

What size is the case? 44mm × 50mm, 16–17mm thick, approximately 140g — one of the largest cases in the HANBORO range, suited to buyers who want a bold oversized watch.
