When it comes to automatic watch movements, enthusiasts often find themselves weighing the merits of various calibers. Two of the most prevalent and respected options in the mid-range market are the Sellita SW200 (a clone of the venerable ETA 2824-2) and the Miyota 9 series. Both offer robust performance and reliability, but they cater to slightly different preferences and price points. Let's dive into a detailed comparison to help you decide which one might be right for your next timepiece.
The Swiss Contender: Sellita SW200 (and its ETA 2824-2 Ancestor)
The Sellita SW200 is a Swiss-made automatic movement that has become a staple in countless watches, especially after ETA began restricting the supply of its movements to third-party brands. It's essentially a clone of the ETA 2824-2, sharing almost identical specifications and architecture.
Key Features:
•Origin: Switzerland
•Type: Automatic, self-winding
•Frequency: 28,800 vibrations per hour (vph) / 4 Hz
•Jewels: 26 (SW200-1) or 25 (ETA 2824-2)
•Power Reserve: Approximately 38-42 hours
•Functions: Hours, minutes, central seconds, date (optional)
•Hacking & Hand-winding: Yes
Pros:
•Proven Design: Based on a decades-old, highly reliable ETA design.
•Smooth Sweep: High beat rate (28,800 vph) results in a smoother second hand sweep.
•Widespread Use: Parts and servicing are readily available due to its ubiquity.
•Accuracy: Generally offers good accuracy out of the box, with potential for further regulation.
Cons:
•Rotor Noise: Some users report a slightly louder rotor noise compared to other movements.
•Price: Tends to be found in watches at a slightly higher price point than those with Miyota movements.
Watches Featuring SW200/ETA 2824-2: Many microbrands and established Swiss brands use this movement. Examples include Oris, Sinn, Christopher Ward, and various Tissot models.
The Japanese Innovator: Miyota 9 Series (9015, 9039, etc.)
The Miyota 9 series, particularly the 9015, emerged as a strong competitor to the Swiss movements, offering high performance at a more accessible price. Produced by Citizen's movement division, Miyota, these movements are known for their slim profile and robust construction.
Key Features (Miyota 9015/9039):
•Origin: Japan
•Type: Automatic, self-winding
•Frequency: 28,800 vibrations per hour (vph) / 4 Hz
•Jewels: 24
•Power Reserve: Approximately 42 hours
•Functions: Hours, minutes, central seconds, date (9015), no date (9039)
•Hacking & Hand-winding: Yes
Pros:
•Slim Profile: Allows for thinner watch cases, a desirable aesthetic for many.
•High Beat Rate: Matches the smooth sweep of Swiss counterparts at 28,800 vph.
•Reliability & Durability: Known for being a workhorse movement that can withstand daily wear.
•Affordability: Often found in watches that offer excellent value for money.
Cons:
•Unidirectional Winding: The rotor only winds in one direction, which can lead to a noticeable
rotor wobble or noise for some users.
Watches Featuring Miyota 9 Series: Popular among microbrands and affordable luxury brands such as Nodus, Zelos, and many Japanese domestic market watches.
Conclusion: Which Movement is Right for You?
Both the Sellita SW200 and the Miyota 9 series are excellent choices for automatic watches, offering reliable performance and a smooth sweep second hand. Your preference will largely come down to subtle differences and what you prioritize in a timepiece.
If you value the traditional Swiss heritage, a slightly quieter rotor, and don't mind a marginally thicker case, the SW200 (or its ETA counterpart) is a fantastic option. It's a tried-and-true movement with a long history of dependable service.
If you're looking for a slimmer watch, appreciate Japanese engineering, and want excellent performance at a more budget-friendly price, the Miyota 9 series is hard to beat. Its thin profile makes it a favorite for dress watches and those who prefer a less bulky feel on the wrist.
Ultimately, both movements represent great value and will serve you well. The choice often comes down to the specific watch design and brand aesthetic that appeals to you most.
