Sellita SW200-2-S-B-POWERPLUS

The Sellita SW200-2-S-B-POWERPLUS is an automatic movement with a ball-bearing oscillating weight that winds the mainspring during wear. It beats at 28,800 vibrations per hour, houses 26 jewels, and delivers a 65-hour power reserve when fully wound. The caliber includes a hacking seconds mechanism and manual winding capability, allowing the wearer to stop the seconds hand for precise time-setting and to wind the watch by hand when needed. This movement appears in various skeletonized watches from brands that source Sellita calibers.
