Zelos lists a 40mm diameter, 47mm lug-to-lug, 11.5mm thickness excluding the crystal, a La Joux-Perret G100 Soigné movement and 200m water resistance. Its official listing showed $799 USD and sold out when checked in 2026. Because no independent wrist test of this exact reference is established here, this overview sticks to documented specifications and clearly distinguishes the separate Spearfish Dual Time.
What the “Forged Carbon” name means on this Spearfish
On this 40mm diver, forged carbon refers to the dial and bezel. Zelos specifies a 316L stainless-steel case, finished with brushed and polished surfaces and a 1200HV hardened coating on the case and bracelet. The bezel is ceramic, and Zelos describes it as a 120-click diver bezel. The watch is therefore not the carbon-case Spearfish Dual Time that appears in some coverage.
Zelos lists the case at 40mm across, 47mm lug-to-lug and 11.5mm thick excluding the crystal. That thickness figure should not be read as the total height including the raised sapphire crystal. The listed lug width is 20mm.

Movement, crystal and bracelet details
The listed caliber is the La Joux-Perret G100 Soigné, finished with gunmetal plating. Zelos also specifies a color-matched date wheel and a display sapphire caseback, so the movement can be viewed from the back. The crystal is sapphire with an inner anti-reflective coating.
The supplied steel bracelet has screw links, a quick-adjust clasp and quick-release spring bars. Zelos lists a 20mm lug width, which makes a separately purchased 20mm strap a possible alternative. Confirm the strap’s actual width and spring-bar compatibility before ordering; lug width alone does not guarantee a particular strap’s fit or end shape.

How it differs from the Spearfish Dual Time
“Spearfish” covers distinct watches, and the Dual Time is not another name for this 200m G100 diver. The Dual Time reviewed by Fratello uses a Sellita SW300 with a TT651 module, adds a second-time-zone display and is rated at 100m in that coverage. Worn & Wound’s Spearfish Dual Time Moonscape is also a different model: it has a forged-carbon case, a canvas strap and a 100m rating. Those reviews’ dimensions, weight and wrist impressions should not be assigned to the Forged Carbon diver.
| Feature | Spearfish 40mm Diver “Forged Carbon” | Spearfish Dual Time coverage |
|---|---|---|
| Carbon component | Dial and bezel; stainless-steel case | The Moonscape covered by Worn & Wound has a forged-carbon case |
| Movement and function | La Joux-Perret G100 Soigné; date | Sellita SW300 with TT651 module; dual-time display |
| Water resistance | 200m, Zelos specification | 100m, as reported for the separate Dual Time |
| Case dimensions | 40mm diameter, 47mm lug-to-lug, 11.5mm thick excluding crystal | 40 × 47mm reported for the Moonscape; thickness not stated in the cited coverage |
The comparison is a model-identity check, not a full head-to-head assessment: the cited Dual Time coverage concerns different configurations and does not establish like-for-like dimensions, bracelet options or pricing for every Dual Time reference.

Price, stock, warranty and returns
When checked in 2026, Zelos’s product page displayed a price of $799 USD and a sold-out status; the Spearfish collection page also showed the Forged Carbon diver at $799 and sold out. Price and inventory can change, so check the Zelos product listing for the current status before making plans to buy.
Fratello reported a historical launch price of $699 for a Forged Carbon dial-and-bezel variant. That is past launch pricing, not the $799 price displayed on Zelos’s page in 2026, and the cited review does not establish that it tested this exact reference.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What can—and cannot—be said about the hands-on experience
The available independent hands-on material concerns either a related Spearfish configuration or the separate Dual Time, not a confirmed wrist test of this exact forged-carbon diver. It therefore cannot substantiate claims about this watch’s weight, comfort, finishing in person, legibility in use or bracelet feel. The dimensions and materials above are documented specifications; they are not a substitute for an on-wrist assessment.
