d.b Posted October 20, 2007 Report Share Posted October 20, 2007 I've heard some quartz movements (e.g. ISA 8162/220) has jewels, like in mechanical movements.. what i don't understand, does a quartz movement can benefit from jewels in some ways? or is it just a gimik ? daytona il Quote Link to comment Share on other sites More sharing options...
jkarpas Posted October 20, 2007 Report Share Posted October 20, 2007 jewels are used to compensate friction on posts, gears and other moving parts of the watch. I am not so aware of how a quatz mvt works in detail but i am sure that reducing the friction in its moving parts contributes to the good timekeeping and reliability Quote Link to comment Share on other sites More sharing options...
