Introduction
The Zelos Mako is a name that resonates with a generation of collectors who refuse to compromise on quality despite a modest budget. Launched in 2015 by Singapore-based microbrand Zelos Watches, the Mako quickly became a benchmark for what an affordable dive watch could achieve. With its aggressive case geometry, superlative lume, and a movement that punches well above its price point, the Mako is not merely a tool watch—it is a statement of intent.
In this review, we dissect every element of the Zelos Mako: from its historical roots in the brand’s mission to democratize high-end specs, to the nuanced finishing of its movement, to how it actually wears on the wrist. Whether you are a seasoned collector or a newcomer seeking your first serious timepiece, the Mako demands attention.
We will explore the movement architecture, case construction, dial execution, and real-world performance. By the end, you will understand why the Zelos Mako has become a cult classic in the microbrand universe and why it remains a compelling choice in 2025.
Manufacture History
Zelos was founded in 2014 by Elshan Tang in Singapore. The brand’s name is derived from the Greek god of zeal, and that passion is evident in every release. From the outset, Zelos aimed to offer specifications typically reserved for luxury watches—sapphire crystal, ceramic bezels, high-grade lume, and robust water resistance—at prices accessible to young professionals and enthusiasts. The Mako, introduced in 2015, was their first dive watch and set the template for the brand’s philosophy: maximum value, minimal compromise. Over the years, the Mako has evolved through several iterations (V1, V2, V3) and material variants (bronze, titanium), each refining the formula while staying true to the original vision.
Movement
The heart of the Zelos Mako is either the Seiko NH35 or the Miyota 9015, depending on the variant. The NH35 is a 24-jewel automatic with hacking and hand-winding, beating at 21,600 vph with a 41-hour power reserve. It is a workhorse movement, proven in countless Seiko and microbrand watches. The Miyota 9015, found in some Mako versions, offers a higher beat rate of 28,800 vph and a slightly slimmer profile, with 24 jewels and 42-hour reserve. Neither movement is COSC-certified, but Zelos regulates them in-house to reasonable tolerances. The finishing is utilitarian—no Geneva stripes or perlage—but the movement is reliable, easy to service, and readily available. For the price, it is the right choice: robust, accurate enough, and serviceable by any watchmaker.

Wrist Feel
On the wrist, the Zelos Mako wears remarkably compact for a 300m diver. The 40mm diameter and 48mm lug-to-lug ensure it sits flat on average wrists, while the 12.5mm thickness (including domed sapphire) slides easily under a shirt cuff. The case is heavily brushed with polished chamfers, giving it a robust yet refined character. The bracelet is substantial but not overly heavy, with solid end links and a comfortable taper from 20mm to 16mm at the clasp. The signed crown at 3 o’clock is easy to grip and screws down with satisfying precision.
The weight is balanced—neither too light nor too heavy—making it suitable for all-day wear. The bezel action is crisp with 120 clicks, and the lume is nothing short of spectacular: Super-LumiNova X1 applied generously on the dial, hands, and bezel insert glows like a torch after a brief charge. This is a watch that disappears on the wrist, only to remind you of its presence with a brilliant blue-green glow in the dark.
Accuracy
In real-world testing, the Seiko NH35 movement in the Zelos Mako typically runs within +10 to +20 seconds per day, which is acceptable for a non-COSC movement. With careful regulation, some examples achieve +5 to +10 spd. The Miyota 9015 variant is often more consistent, averaging +5 to +15 spd. For daily wear, the accuracy is more than sufficient; the watch is a tool, not a chronometer, and its reliability far outweighs minor deviations.
Occasions
The Mako is versatile enough for sport, daily wear, travel, and even dressier settings (especially with a leather strap). Its 300m water resistance makes it a capable dive companion, while the compact size and refined finishing allow it to pass as a casual everyday piece. It is not a formal watch, but it can hold its own in a business casual environment.
Wrist Presence
4/5 – The Mako commands attention without being ostentatious. Its bold hands, generous lume, and aggressive bezel give it a purposeful look that stands out in a sea of black-dial divers. Yet the 40mm size keeps it from being overbearing. It is a watch that says 'I know what I'm wearing' without shouting.
Reference Variants
The Mako has been released in numerous limited editions and material variants. Common references include the Mako V3 (stainless steel, various dial colors), Mako Bronze (bronze case, patina potential), and Mako Titanium (lightweight titanium). Each variant may use a different movement (NH35 vs Miyota 9015) and different bezel materials (ceramic vs sapphire). Dial colors range from classic black and blue to vibrant orange, teal, and green. Some editions feature textured dials like sunburst or meteorite.
Family References
The Mako family includes the V1, V2, V3, and special material editions. The V3 is the most refined, with a slimmer case, improved bracelet, and updated dial details. The Bronze and Titanium versions offer alternative case materials for collectors seeking something different.
Other Notable Models by Zelos
Beyond the Mako, Zelos produces the Spearfish (a 300m diver with a more traditional case), Horizons (a GMT), Eagle (a pilot watch), Nova (a dress watch), and Swordfish (a vintage-inspired diver). Each model carries the brand’s signature high-spec, affordable ethos.
Similar Watches
In the same price and style bracket, the Seiko Prospex SPB143 offers a similar 40mm diver with 200m WR and a more traditional aesthetic, but at a higher price. The Orient Kamasu is another affordable automatic diver with similar specs, though its lume and finishing are not as refined. The Christopher Ward C60 Trident Pro 300 is a step up in price with a more premium movement and finishing, but comparable design philosophy.
Homages
For those on a tighter budget, the Invicta Pro Diver 8926OB is a direct homage to the Rolex Submariner, but lacks the Mako's unique design and lume quality. The Steeldive SD1970 is a homage to the Seiko Turtle, offering sapphire and ceramic bezel at a very low price, but with less refined finishing.
Investment Value
The Zelos Mako is not an investment piece; it is a tool watch meant to be worn. Pre-owned values hold reasonably well due to limited production runs, but do not expect appreciation. Buy it to enjoy it. MSRP is around $499, and pre-owned examples typically sell for $300-$450. No major auction history exists.
Service Interval
Zelos recommends a service every 5 years. The cost is approximately $200 for a standard movement service, and any competent watchmaker can handle it. Parts are widely available, and authorized service is not required.
Pros and Cons
Pros: Superlative lume, robust 300m water resistance, excellent case finishing, comfortable 40mm size, reliable movement.
Cons: Movement accuracy can be inconsistent, bracelet clasp lacks on-the-fly micro-adjust, limited brand recognition, some dial colors are limited runs.
Final Verdict
The Zelos Mako is a masterclass in value-driven microbrand watchmaking. It offers a level of finishing, lume, and water resistance that challenges established Swiss and Japanese brands at multiples of the price. While it may not hold its value as an investment, it delivers immense satisfaction as a daily wearer. For the discerning young collector who demands performance without pretension, the Mako is an essential addition to any rotation.
