Al-Biruni o ne a kgaoganya ura ka metsotso, metsotswana, boraro le bone ka ngwaga wa 1000 CE fa a ne a bua ka dikgwedi tsa Sejuta.[4]
Go ya ka hisitori, lefoko "motsotso" le tswa mo lefokong la Selatine pars minuta prima, le le rayang "karolo ya ntlha e nnye". Karolo eno ya ura e ka tokafadiwa gape ka "karolo e nnye ya bobedi" (ka Selatine: pars minuta secunda), mme lefoko "beke" le tswa mo go seno. Go tokafatsa go ya pele, lefoko "third" (1⁄60 ya motsotswana) le santse le le teng mo dipuong dingwe, sekao Se-Poland (tercja) le Se-Turkey (salise), le fa tiriso ya segompieno e arola metsotswana ka go dirisa dinomoro tsa bosome. Letshwao la motsotso le motsotso wa bobedi le ka bonwa jaaka le le supang sekgala sa ntlha le sa bobedi sa ura (go tshwana le kafa leoto e leng sekgala sa ntlha sa jarata kana gongwe ketane, ka disentimetara e le sekgala sa bobedi). Ka 1267, moitsesaense wa metlha ya bogare e bong Roger Bacon, a kwala ka Selatine, o ne a tlhalosa gore nako e e fa gare ga ngwedi o o tletseng ke palo ya diura, metsotso, metsotswana, boraro le bone (horae, minuta, secunda, tertia le quarta) morago ga sethoboloko ka matlha a a rileng a khalendara. [5]Go tsenngwa ga letshwao la metsotso mo ditshupanako go ne ga kgonega fela morago ga go tlhamiwa ga hairspring ke Thomas Tompion, modiri wa ditshupanako wa Moesemane, ka 1675. [6]
