BONEST GATTI BG6601 Whirlwind Automatic Skeleton Watch

BONEST GATTI BG6601 Whirlwind Automatic Skeleton Watch

The BONEST GATTI BG6601 Whirlwind Series combines a large cushion-shaped case with an open-worked, multi-level dial and bright motorsport-inspired accents. Its 44.2mm case, visible mechanical components and contrasting subdial architecture give it a much more technical appearance than a conventional round automatic watch.

A mechanical automatic movement powers the watch, while sapphire crystal, a 316L stainless steel case and a stitched leather strap build the BG6601 around materials suited to regular wear. Multiple accent colors are available, including blue, green, yellow, red and orange.

Specifications

Whirlwind Series Design

The BG6601 uses a round dial inside a broad cushion-shaped case, giving the watch a distinctly architectural profile. Four exposed screw-style details emphasize the corners, while the layered chapter ring and partially open dial create considerable depth beneath the sapphire crystal.

Bright color is concentrated around the minute track, hands, subdials and strap stitching. This keeps the black central structure dominant while allowing each version to have a clearly different personality.

The blue version delivers the strongest contrast against the dark case, while green, yellow, red and orange variants provide increasingly aggressive motorsport-inspired combinations.

Open-Worked Mechanical Dial

Instead of hiding the movement behind a conventional solid dial, the BG6601 exposes portions of its mechanical construction through the center and lower sections of the display.

Two offset circular displays add another layer to the design, surrounded by contrasting scales and metallic components. The result is closer to an industrial instrument panel than a traditional dress watch.

For another mechanical watch with a very different traditional layout, see the Corgeut 42mm ST3600/ST3601 Hand-Wound Watch.

Automatic Mechanical Movement

The BG6601 uses the BT16-01G automatic mechanical movement listed for the Whirlwind Series. The manufacturer specifies approximately 42 hours of power reserve.

Automatic winding allows normal wrist movement to replenish the movement’s mainspring during wear, removing the need for a battery.

If you prefer a more conventional automatic sports-watch format, the Corgeut NH35 41mm Automatic Diver Watch offers an NH35 movement, rotating dive bezel and stainless steel bracelet.

316L Stainless Steel Case

The substantial 44.2mm case is made from 316L stainless steel and measures approximately 13.5mm thick.

Its squared profile gives the watch considerably more wrist presence than the diameter alone suggests. Angular corners, recessed dial construction and the oversized crown reinforce the mechanical, performance-oriented appearance.

The caseback continues the industrial styling with engraved detailing and a central opening that provides a partial view of the movement.

Sapphire Crystal

A sapphire crystal protects the complex dial structure. Sapphire offers strong resistance to everyday scratches and is especially useful on a watch with a large crystal area such as the BG6601.

Leather Strap

The pictured configurations use a black leather strap with stitching matched to the dial accents. The strap is approximately 26mm wide, appropriately proportioned for the large case.

A conventional pin buckle keeps the fastening straightforward, while the contrast stitching visually connects the strap with the blue, green, yellow, red or orange dial details.

For a smaller automatic watch with a cleaner steel-bracelet design, see the Corgeut 36/39mm NH35 Miyota Automatic Watch.

Color Options

The Whirlwind Series is available in several combinations:

• Blue – blue dial accents with matching blue strap stitching
• Green – green accents and stitching
• Yellow – yellow accents and stitching
• Red – red accents and stitching
• Orange – orange accents and stitching

Both dark and silver-tone case treatments are shown across the available configurations.
