Luthier 1 Posted July 6, 2011 Apparently Sellita has modified their SW 200 into the SW 200-1 In their own words... "SW 200... The tooth profile realized follows the norm NIHS 20-25, which does provide a good power transmission. The individual tooth has a slim geometry and it has occasionally occured at strong shocks, that the teeth have been damaged." "SW 200-1... The tooth profile realized follows the norm Sellita, which does provide an equal power transmission but does provide a strengthened connection between the gears. http://www.sellita.ch/index.php?option=com...=22&lang=en http://www.sellita.ch/images/stories/docum..._v.16.04.10.pdf Share this post Link to post Share on other sites
