Movement Specs

Sellita SW200 Automatic Movement

A Proven Swiss Mechanical Standard

The Sellita SW200 is a Swiss-made automatic mechanical movement recognized throughout the watch industry for its proven architecture, dependable performance, and long-term serviceability.

Manufactured by Sellita in La Chaux-de-Fonds, Switzerland, the SW200 is designed as a practical mechanical engine for everyday wear. Its automatic winding system transforms the natural motion of the wrist into stored energy, while hand-winding and stop-seconds functions provide greater control when setting the watch.

Operating at 28,800 vibrations per hour, the movement delivers a smooth mechanical seconds sweep and stable timekeeping performance. Its 26 synthetic jewels reduce friction at key contact points, supporting durability throughout years of regular use.

For Marvin, the SW200 is selected for watches where reliability, performance, and ease of professional servicing are essential. Visible through an exhibition caseback on selected models, it reveals the precise interaction of the rotor, gear train, balance, and escapement.

The SW200 does not rely on novelty alone. Its strength lies in something more valuable: a mature Swiss construction trusted by watchmakers and designed to perform consistently in the real world.

Swiss engineered. Proven over time. Ready for every day.

Accuracy Guarantee

We certify and guarantee that your timepiece will be accurate ±10 seconds per day, which in watchmaking terms means exceptional precision.

Customer photo review of Round Official COSC Precision Watch

The fact that it's a Swiss-made, officially certified chronometer is what sold me on this watch. It has a great feel on my wrist—substantial and premium, but not overbearing. It is simple to operate and easy to read. Finally, I'm happy that it came with a leather strap, and it's relatively simple to swap between leather and metal.
