Unimatic vs Zelos: Two Microbrands That Couldn't Be More Different
Unimatic and Zelos both make sub-£1,000 tool watches with limited production runs, Japanese movements, and cult followings. On paper, they compete directly. In practice, they're opposites.
Unimatic strips everything back — minimal text, monobloc bezels, industrial shapes, and a design language that says nothing it doesn't have to. Zelos piles everything on — exotic materials, wild dial options, titanium cases, and a spec sheet that reads like a brand twice the price.
One is a concrete wall. The other is a candy shop. This comparison helps you figure out which suits you.
The Quick Answer
Buy Unimatic if: You want restraint, design identity, and a watch that looks like nothing else. You value the visual over the spec sheet. You understand that less can be more — and you're willing to pay for that subtraction.
Buy Zelos if: You want the most materials, specs, and variety for the money. Titanium, meteorite dials, 300m WR, sapphire bezels — Zelos gives you options nobody else at this price offers. You buy watches for what they're made of.
Design Philosophy
Unimatic is an Italian design studio that makes watches. Founded in Milan by Giovanni Moro and Simone Nunziato, both with backgrounds in architecture and industrial design. Every Unimatic looks like it was designed by someone who's read Dieter Rams and means it. Flat, geometric bezels. Minimal dial text. Matte finishes. No unnecessary detail. The Modello Uno (diver) and Modello Due (field) are the core platforms — everything else builds on those foundations.
Unimatic releases in limited batches of 100–600 units. Once they sell out, they're gone. The scarcity is real — Unimatic doesn't restock the same reference. This creates secondary market demand and gives each piece a collector quality that most sub-£1,000 watches don't have.
Zelos is a Singapore-based brand founded by Elshan Tang. Zelos does the opposite of Unimatic in almost every way: more materials (titanium, bronze, carbon, Damascus steel, meteorite), more dial options (abalone, aventurine, forged carbon, coral), more complications (GMT, dive bezels), and more variety per drop. A single Zelos release might have 15 colourway and material combinations.
Zelos also does limited runs, but the sheer volume of variants means there's usually something available. Secondary market demand exists but is less intense than Unimatic because supply is broader.
The difference: Unimatic edits. Zelos maximises. A Unimatic looks like one person's vision executed without compromise. A Zelos looks like a materials science lab crossed with a spec-sheet competition.
The Divers: Modello Uno vs Mako / Swordfish
Unimatic Modello Uno UC1 (~£600–£775): 40mm, Seiko NH35A, 300m WR, double-domed sapphire, monobloc fixed bezel (no rotating bezel), DLC or steel options. Minimal dial text — just the essentials.
Zelos Mako V3 (~£350–£500): 40mm, Seiko NH35A, 300m WR, sapphire crystal and bezel insert, rotating bezel, titanium or steel. Dial options include meteorite, forged carbon, and standard colours.
Zelos Swordfish (~£400–£600): 40mm, Seiko NH35A, 300m WR, titanium, sapphire, exotic dial materials. The chunkier alternative to the Mako.
The gap: Unimatic costs more and gives you less — no rotating bezel, no exotic materials, no titanium (in the standard UC1). What you're paying for is the design. The monobloc bezel, the proportions, the restraint. It's a premium for aesthetic intent, not materials.
Zelos gives you significantly more per pound spent. Titanium cases, sapphire bezel inserts, exotic dials, 300m WR — for £100–£300 less than Unimatic. If you're comparing spec sheets, Zelos wins by a landslide. If you're comparing design coherence, Unimatic wins just as decisively.
Beyond Divers
Unimatic offers: Modello Uno (diver), Modello Due (field), Modello Tre (chrono), plus the U2-GMT variant of the Modello Due. All share the same design DNA — geometric, minimal, industrial. Collaborations (with Hodinkee, Massimo Vignelli's estate, and others) add limited variety but stay on-brand.
Zelos offers: Mako (diver), Swordfish (diver), Hammerhead (diver), Spearfish (GMT), Nova (dress/casual), Skyraider (pilot), Visionary (open-heart). The range is significantly broader with more complications and case shapes than Unimatic.
Zelos covers more ground. Unimatic goes deeper into fewer things.
Materials and Build
Unimatic: 316L steel is the standard. DLC coatings on some models. Double-domed sapphire crystals. Matte finishing throughout. The build quality is good but not exceptional for the price — you're paying for design, not finishing. The cases are solid, the crystals are good, the movements are basic Seiko automatics. No titanium in the core diver range (the ProDiver uses steel).
Zelos: Titanium is available across most collections. Grade 5 titanium cases, sapphire bezel inserts, exotic dial materials (meteorite, forged carbon, Damascus steel, coral, abalone). For the price, the material variety is unmatched. Finishing is functional — brushed surfaces, sharp edges, competent but not refined. You get material value, not hand-finishing value.
Verdict: Zelos wins on materials by a wide margin. Unimatic wins on design cohesion. Neither brand offers the hand-finishing of a Halios or Christopher Ward at higher prices.
Movements
Both brands primarily use Seiko NH35A movements across their diver ranges. The NH35A is a 41-hour power reserve, 21,600 bph, hacking and hand-winding automatic. It's reliable, cheap to service, and entirely adequate for the price.
Unimatic has expanded into the Seiko NH34A (GMT) for the Modello Due U2-GMT. No Swiss movement options.
Zelos uses the Miyota 9075 (true GMT) in the Spearfish, which is a significant upgrade over the NH35A — 28,800 bph, 42-hour reserve, and an independently adjustable local hour hand. Some Zelos models also use Swiss movements in limited editions.
Verdict: Zelos has the edge — the Miyota 9075 in the Spearfish GMT is a better movement than anything Unimatic currently uses. For the divers, it's a draw (both NH35A).
Buying Experience
Unimatic drops limited batches on their website. Popular models sell out in hours. No restocks of the same reference. If you miss a drop, your options are secondary market at a markup. Prices in EUR, ships from Italy. UK customs may apply.
Zelos does pre-order drops with more availability. The wider range of variants means less scarcity pressure. Some models stay available for weeks or months. Prices in USD or SGD, ships from Singapore. UK customs may apply.
Verdict: Zelos is easier to buy. Unimatic requires more attention and speed.

Buy Unimatic if: Design matters more than specs. You want something that looks like it belongs in a design museum. You're comfortable paying more for less material and more intention. You treat your watch as part of your visual identity.
Buy Zelos if: Value matters more than aesthetics. You want titanium, exotic dials, and 300m WR for under £500. You like variety and options. You treat your watch as a tool with personality.
Buy both if: A Unimatic Modello Uno as the design piece. A Zelos Spearfish GMT as the travel beater. Different jobs, zero competition between them.
