Spearfish

Mid-range $600–900

The Zelos Spearfish 40mm Diver is a Singapore microbrand's flagship 200m sport diver, pairing a 316L stainless steel case hardened to 1200HV with the Swiss La Joux-Perret G100 Soigné automatic movement. Released in early 2022 in three dial variants — Forged Carbon, Burnt Orange, and Antique Green — it set a new benchmark for movement quality at the sub-$800 price point.

On the wrist

The Spearfish earns its reputation on the wrist rather than on paper. At 40mm across and a trim 47mm lug-to-lug, it sits flush on a medium wrist and slips under a cuff without protest — the downward-tapered lugs follow the contour naturally. The 1200HV coating on both case and bracelet is one of those details you don't fully appreciate until a month in, when the watch still looks pristine where an equivalent uncoated piece would show a constellation of micro-scratches. The 120-click ceramic bezel is among the tightest-action dive bezels in this segment: no wobble, no slop.

The dial variants offer real character without gimmickry. The forged carbon reads like living texture under shifting light; the fumé orange and green develop genuine depth from the treatment rather than being flat-painted. BGW9 blue on the seconds hand against C3 green on the other markers is a thoughtful lume layout — practical and distinctive rather than showy. Flipping the watch over to the display caseback and seeing the gunmetal-plated G100 movement is the kind of detail that makes this feel like more than a spec-sheet exercise. If you're stepping up from a budget Seiko and want to understand what twice the price buys, this watch makes the argument clearly.

Bottom line

One of the most movement-generous dive watches under $800 — the Soigné-grade LJP G100 and hardened-steel build deliver credibility well above the price, which is exactly why all base-diver variants sold out.

Who it's for

Buyers who want genuine Swiss-movement quality in a sub-$800 dive watch and wear a medium wrist (roughly 6.5–7.5 inches) that benefits from a compact 47mm lug-to-lug. Well suited to those who prioritize build quality and movement finishing over heritage brand names, and who are comfortable purchasing from a smaller Singapore-based direct-to-consumer microbrand.

Who should skip it

Skip it if you need 300m+ depth rating, a watch with an established secondary market, or a piece available off-the-shelf — all base-diver variants were sold out at last check.

Before you buy

All base-diver colorways sold out on the official site at last check — confirm availability before purchasing
Thickness spec of 11.5mm is 'without crystal' — actual wearing depth with domed sapphire is higher
Multiple Spearfish tiers exist (base diver, GMT at ~$999, Dual Time Ti at ~$2,199) with very different specs — confirm you have the right model
No COSC or third-party certification — the Soigné ±7 s/day rating is La Joux-Perret's own grade

FAQ

Is the Spearfish automatic or quartz?

It runs a automatic movement.

What movement does the Spearfish use?

The La Joux-Perret G100 (La Joux-Perret).

Does the Spearfish have a date?

Yes.

How water resistant is the Spearfish?

It is rated to 200 m.

How big does the Spearfish wear?

40 mm wide with a 47 mm lug-to-lug.

How does the Spearfish differ from the Zelos Swordfish?

The Spearfish is Zelos's step-up diver: the case and bracelet are hardened to 1200HV for meaningfully better scratch resistance, the movement upgrades from the Seiko NH35 common in Swordfish models to the Swiss LJP G100, and polished chamfers with downward-tapered lugs give a more finished silhouette.

What makes the La Joux-Perret G100 notable at this price?

La Joux-Perret is a genuine Swiss-made movement manufacturer based in La Chaux-de-Fonds, typically supplying brands that charge multiples of the Spearfish's price. The G100 beats at 28,800 bph for a smoother sweep, offers a 68-hour power reserve, and in Soigné grade is rated ±7 s/day — noticeably better than the ±15–20 s/day common in budget automatics.

Are there other Spearfish variants besides the base diver?

Yes. Zelos expanded the line to include a GMT variant (Sellita SW330-2, 200m, ~$999) and a Dual Time Titanium series (Sellita SW300 + TT651 module, 100m, ~$2,199 in titanium or forged carbon). Each sub-line carries different movement, case material, and water-resistance specs from the original base diver.
