Soo koob maqaalka:  Saacad ku salaysan naqshad la sameeyay 300 sano ka hor ayaa la yaab ku noqotay khubarada waayo waxay sax u ahayd ilbiriqsi 100 maalmood. Saacadda casriga ah ee Martin Burgess Clock B waxay ku salaysan tahay saacaddii John Harrison ee qarnigii 18aad, taas oo uu u maleeyay inuu xalliyo dhibaatada go'aaminta dhererka badda. Waxay qeyb ka ahayd tijaabo 100 maalmood ah oo lagu sameeyay Royal Observatory, oo ku taal Greenwich, si loo arko haddii sheegashada - in saacaddu aysan lumin doonin ama ku kordhin doonin wax ka badan hal ilbiriqsi 100 maalmood gudahood - ay run ahayd. Saacadda Martin Burgess B (bidix), oo ku saleysan naqshad uu sameeyay ninka dhirta dhisa ee John Harrison (midig) 300 sano ka hor, ayaa la yaabay khubarada iyadoo sax ah illaa ilbiriqsi 100 maalmood. Saacadda, oo loo dhisay qalab casri ah, ayaa markii hore la bilaabay in ay shaqeyso sanad ka hor ka dib markii lagu xiray mid ka mid ah tiirarka taageeraya Observatory. Laakiin si dhakhso ah ayey u muuqatay in tijaabada ay noqon doonto guul waxaana la saaray shaabadaha wax lagu xiro si loo xaqiijiyo saxnaanta, Independent on Sunday ayaa soo warisay. Waqtiga waxaa lagu qiyaasay saacad raadiyaha lagu xakameeyo, oo heshay calaamadda waqtiga qaranka, iyo saacadda BT ee hadalka. Jonathan Betts, oo xubin ka ah ururka Antiquarian Horological Society, ayaa yiri: 'Markii aan saacada bilownay waxay ahayd wax iska cad in ay si fiican u shaqeyneyso, markaa kadib waxaan helnay kiiska la xiray sababtoo ah qofna ma rumeysan doono sida saacada si fiican u shaqeyneyso.' Wuxuu intaas ku daray in saacaddu aysan ahayn mid la mid ah ta Harrison, laakiin ay isticmaashay naqshaddiisa iyo fikraddiisa. "Waxaa muhiim ah in la ogaado in naqshadiisu ay ka soo horjeedo wax kasta oo aasaasku sheegtay inay tahay tan ugu fiican taariikhda oo dhan", ayuu raaciyay Mr Betts. Saacadda casriga ah ayaa tan iyo markii ay shahaado ka heshay Guinness World Records, taas oo ay ku xaqiijisay Matxafka Badda Qaranka ee Twitter. Saacadda Martin Burgess B waxay qayb ka ahayd tijaabo 100 maalmood ah oo lagu sameeyay Royal Observatory (kor ku xusan), oo ku taal Greenwich, si loo arko haddii sheegashada - in saacaddu aysan lumin doonin ama ku kordhin doonin wax ka badan hal ilbiriqsi 100 maalmood gudahood - ay run ahayd.
