Sellita SW200-1 Technical Specification
Sellita SW200-1 is a mechanical automatic movement known for its precision and reliability. It vibrates at a frequency of 28,800 vibrations per hour (4 Hz) to ensure accurate timekeeping. Composed of 26 jewels, the movement runs smoothly to minimize friction, and with a power reserve of approximately 38 hours, the SW200-1 movement is reliable enough to wear every day. For more information, please refer to the chart below.
Sellita SW200-1 Grade
The grades for specific movement numbers may vary, but below are the specifications for the commonly used sw200-1 and SW215-1, on which many Sellita movements are based. Each grade offers a different level of precision and finishing. These sellita sw200-1 accuracy grades include Standard, Special, Premier and Chronometer.
Standard – adjustable in two positions; accuracy of +/-12 seconds/day up to +/- 30 seconds/day
Special – adjustable in three positions; accuracy from +/-7 sec/day to +/- 20 sec/day
Premium – adjustable in five positions; accuracy +/- 4 sec/day up to +/- 15 sec/day
Chronometer – meets COSC (Swiss Official Chronometer Certification) standards.
Sellita SW200 vs SW200-1
People often compare the Sellita SW200 and SW200-1 calibers to their similarities. While both are Swiss-made automatic movements, the SW200-1 is an upgraded version of the SW200, which adds a hacking function for precise time setting. It also has an improved shock-absorbing system for increased durability and resistance to external shocks.
Despite the evolution and upgrades from the SW200 to the SW200-1, the problem of the ratchet/gear teeth being broken off because of the manual winding movement still exists.
Crown/Step Removal
The crown/step removal process is an important part of watch care and maintenance. It involves carefully removing the crown or stem from the movement for repair or replacement. The crown should be in the time setting position before being removed (two turns out). Use a 1 mm screwdriver and avoid using tweezers or other tools with a pointed tip, as this may catch the regulating stem and damage the regulating stem spring.
If available, we recommend it to seek professional help or consult an allowed service center when removing the crown/step to avoid any damage.
In short, the Sellita SW200-1 movement is an excellent alternative to the ETA 2824-2 and is popular among watch enthusiasts. Sellita has a long history of producing high-quality movements and is a reliable choice for watchmakers and collectors alike.
