Comprei um megir drum roller e estava +1,5 seg dia. Retirei o cristal e fiz a aferição 32.768.020 😮😮😮. Fiz os cálculos e coloquei um cristal 32.767.400 e ok 👍

[@chavijr9020]

Problemas: 1- o equipamento de aferição tem que estar 100% calibrado 2- retirar o cristal do relogio e colocar em 36 graus se for de pulso, se for despertador fora de pulso deixar em temperatura ambiente 3- ter um oscilador com amplitude 100% aferido 4- conseguir bons cristais 5- cristal 32.768.100 é um otimo cristal mas vai adiantar 8 segundos por mes 6- cristal 32.768.500 vai adiantar 30 segundos por mes 7- 32.768 não serve de referencia 8- o c.i divisor de frequência dos relogios tambem sofrem desgaste. Eu tenho um despertador de 30 anos e adianta 1 segundo por dia com 32.767.900

So are skmei accurate? Sorry I don’t understand the video

When my watch was brand new, all was good and accurate. After a couple years accuracy was very decreased. Problem was in quartz.
