Miyota vs Selita vs ETA: The Battle of the Workhorses

Let's talk about something that doesn't get enough attention in the watch world: the engines that power our beloved timepieces. Today, we're diving into a friendly competition between three of the most important movement manufacturers: Miyota, Selita, and ETA.

The Players in Our Game

Think of these movements as the engines in your car. Sure, everyone knows Ferrari makes engines, but what about the reliable Toyota engine in your daily driver? That's kind of what we're talking about here.

Miyota: The Japanese powerhouse, part of Citizen Watch Co., known for their innovative manufacturing processes
Selita: The Swiss challenger, who evolved from being an ETA parts supplier to a full-fledged movement manufacturer
ETA: The Swiss giant, owned by the Swatch Group, and historically the industry's dominant force

A Brief History Lesson

Miyota's Story

Miyota's journey began in 1959 as part of Citizen's manufacturing arm. Their breakthrough came in the 1980s when they revolutionized the industry with high-precision automated manufacturing processes. This allowed them to produce reliable movements at scale while maintaining exceptional quality control standards.

Selita's Rise

Selita's history is deeply intertwined with ETA. For decades, they manufactured parts for ETA movements before the Swatch Group's decision to restrict movement sales forced them to develop their own calibers. Their intimate knowledge of ETA's designs allowed them to create compatible alternatives that often matched or exceeded the original specifications.

ETA's Dominance

ETA, founded in 1793, became part of the Swatch Group in 1983. For decades, they were the industry's primary movement supplier, powering everything from modest Hamiltons to luxury Omegas. In 2019, the Swiss competition authority allowed ETA to reduce movement supply to competitors, changing the industry landscape forever.

The Tale of the Tape

Let's compare their flagship movements: the Miyota 9015, Selita SW200-1, and ETA 2824-2.

Price Points and Market Position

Movement Costs (Approximate Bulk Prices to Manufacturers):

Miyota 9015: $75-90
Selita SW200-1: $180-220
ETA 2824-2: $200-300 (when available)

Who Uses What?

Miyota 9015 Watches:

Zelos Horizons GMT ($899)
Baltic Aquascaphe ($650)
Brew Metric ($495)

Selita SW200-1 Watches:

Oris Aquis Date ($2,200)

Tudor Black Bay 36 ($3,575)
Longines Hydroconquest ($1,600)
Hamilton Khaki Field Automatic ($625)

The Market Reality

The movement landscape has changed dramatically since ETA's supply restrictions. Many brands have adapted by:

Developing in-house movements (like Tudor with their MT series)
Switching to Sellita (like Oris)
Embracing Miyota (like many microbrands)
Using alternative suppliers like STP (Swiss Technology Production)

Real Talk: Which One's Better?

Here's the truth: neither is "better." They're just different, like choosing between sushi and fondue.

Miyota Pros:

More affordable
Often more shock resistant
Great power reserve
Reliable as a Swiss train (ironic, right?)

Selita Pros:

Swiss-made bragging rights
Slightly smoother winding feel
More consistent accuracy
Easier to service (more watchmakers know them)

ETA Pros:

The industry benchmark for reliability
More consistent accuracy
More power reserve
Easier to service (more watchmakers know them)

The Plot Twist

Timepiece Trivia

Here's something interesting: some Swiss brands use Miyota movements, while some Japanese-designed watches use Selita. It's a small world after all!

Technical Deep Dive

ETA vs Selita: The Technical Details

While the SW200-1 is often called a "clone" of the 2824-2, there are subtle but important differences:

Base Plate Architecture

ETA: Uses a slightly thicker main plate with more brass content
Selita: Employs a marginally thinner plate with modified alloy composition
Impact: ETA's design provides marginally better stability, while Selita's approach offers slight weight reduction

Escapement Design

ETA: Traditional Swiss lever escapement with proprietary ETACHRON regulator
Selita: Modified Swiss lever with INCABLOC shock system and unique fine adjustment mechanism
Key Difference: Selita's escape wheel has slightly different tooth geometry

Winding System

ETA: Classic reversing wheel system with 4 components
Selita: Modified reversing wheel system with 5 components
Result: Selita's design can provide smoother winding but with slightly more parts to maintain

Parts Interchangeability

While about 90% of parts are interchangeable between ETA and Selita, key differences include:

Automatic winding bridge
Balance wheel assembly
Barrel arbor dimensions

A Note on Kenissi

While not in direct competition with our main three players, Kenissi deserves mention as a rising force in the movement industry. Founded in 2016 as a joint venture between Tudor and Chanel, Kenissi represents the industry's shift toward vertical integration.

Their MT5600 series movements feature:

70-hour power reserve
COSC certification standard
Silicon hairspring
Free-sprung balance

You'll find Kenissi movements in:

Tudor (MT5402, MT5612)
Norqain (NN20/1)
Chanel (Caliber 12.1)
Breitling (B20)

The emergence of Kenissi shows how the industry is evolving beyond the traditional ETA-dependent model, though their movements occupy a different market position, typically appearing in watches above the $3,000 price point.

What This Means For You

If you're shopping for a watch in the $500-2000 range, you'll probably encounter both. Here's what you need to know:

Don't stress about it: All three are solid choices
Focus on the whole package: The movement is just one part of the watch
Consider service costs: Factor this into your budget
Think about your usage: Daily beater? Dress watch? This matters more than the movement brand

The Bottom Line

All three make great movements. It's like choosing between different types of coffee – espresso, cappuccino, or cold brew. Each has its own distinct flavor and preparation method, but they all provide that essential caffeine kick.

The real winner? Us watch enthusiasts. Competition between these manufacturers keeps prices reasonable and quality high. Plus, it gives us something to debate over coffee at watch meetups!

Final Thoughts

The movement in your watch tells a story about the industry's evolution. ETA's dominance led to standardization, Selita's rise shows the market's adaptability, and Miyota's success demonstrates that quality knows no borders. Whether you're wearing an ETA, Selita, or Miyota, you're wearing a piece of watchmaking history.
