Introducing
Swiss Movement
Powered by a Swiss automatic movement crafted for unmatched precision, reliability, and timeless performance.
Sellita SW200-1
The Swiss Heart Within
Beneath every Surani timepiece lies a Swiss movement — the silent force of precision and grace. Crafted in Switzerland by master watchmakers, it embodies centuries of horological artistry and innovation. Operating at 28,800 vibrations per hour, its rhythm mirrors the heartbeat of perfection.
With 26 hand-set jewels ensuring flawless motion and lasting endurance, each mechanism is engineered to stand the test of time. The result is a seamless harmony of power, precision, and poise — a movement that transforms every Surani watch into a living testament to Swiss excellence and Indian soul.

28'800 vibrations/hour (4 Hz/second)
Power reserve
38 Hours
Balance & Escapement
Gold-colored (gilt) balance wheel with Nivatronic alloy hairspring (antimagnetic alloy).
Balance staff is Epilame‑coated (anti‑oil‑run treatment)
Shock Protection
Incabloc shock-absorber on the balance staff

Design and Manufacturing
Made in Switzerland, Manufactured by Sellita
Movement Type
Swiss-made automatic (self-winding) mechanical movement (round caliber, Swiss lever escapement)
Functions
Central hours, minutes, seconds; date (at 3:00) with quick-correction (rapid date set) via crown
Winding
Automatic via central oscillating weight (bi‑directional winding), also supports manual hand-winding by the crown (standard direction)
Hacking
Yes – stop‑second function (movement stops when crown is pulled)
Weight
Oscillating weight has a heavy-metal (tungsten-alloy) segment on a ball-bearing pivot (for efficient bi-directional winding).
Stem & Crown
Three-position winding stem:
Pos1 = winding (and “date change” at midnight) with manual winding enabled; Pos2 = rapid date-correction; Pos3 = time setting/hacking
Components
Fine-timing device (regulator screw) is provided. The movement uses high-grade alloys (e.g. Nivatronic hairspring, gilt wheel) for temperature stability
Rotor & Winding Train
Central oscillating weight with heavy-metal (tungsten alloy) rim segment, running on ceramic/metal ball bearings for smooth bi-directional winding
