Spearfish
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.

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.
Highlights
- Swiss La Joux-Perret G100 Soigné (68 h power reserve)
- 1200HV hardened case & bracelet
- 40mm / 47mm L2L — compact wear
- 120-click dive bezel (ceramic; forged carbon on Forged Carbon variant)
- Display sapphire caseback
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?
The Spearfish is automatic. The La Joux-Perret G100 winds itself from the motion of your wrist, so it needs no battery. A full wind holds roughly 68 hours, so it keeps running overnight off the wrist; left longer it stops and restarts once you wear or hand-wind it.
What movement does the Spearfish use?
The Spearfish is powered by the La Joux-Perret G100 from La Joux-Perret, an automatic caliber with 24 jewels, a 68-hour power reserve, and a 28,800 bph beat rate. Being automatic, it winds from the motion of your wrist and needs no battery.
Does the Spearfish have a date?
Yes — the Spearfish has a date display on the dial. The date advances automatically as the movement runs, so the current day of the month is always visible at a glance, and you can set it from the crown after the watch has been left to stop.
How water resistant is the Spearfish?
The Spearfish is rated to 200 m. That is true dive territory: fine for swimming, snorkelling and recreational scuba diving, as well as all daily wear. Whatever the rating, avoid operating the crown or pushers underwater, and have the gaskets checked periodically to keep it reliable.
How big does the Spearfish wear?
At 40 mm across with a 47 mm lug-to-lug and 11.5 mm thick, the Spearfish wears as a modern medium-to-large watch. Lug-to-lug is the measurement that really decides fit, since it sets how far the case spans the wrist — 47 mm suits most wrists, and smaller wrists especially should check that figure.
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.
