At the core of our watches Sherpa Ultradive, Sherpa OPS and Sherpa x TRTS OPS lies the Mantramatic MM01 movement, which is based on the well known and established Swiss automatic mechanical movement Sellita SW200-1, gold plated, decorated and regulated to top standard. It has two wheels, namely the seconds and the escape wheel, modified and converted into micro prayer wheels giving out good vibrations into the world with every tick it makes.
