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.

Poseidon Art Dial with Classical Details

The white dial incorporates a finely rendered Poseidon illustration alongside a distinctive combination of Roman numerals and applied baton hour markers. The layout balances classical elegance with the commanding strength of its mythological subject.

Rated to 50 meters of water resistance, the watch is suitable for daily exposure such as rain, hand washing, and occasional splashes.

Avoid swimming, showering, diving, and operating the crown while the watch is wet.
