Nws yog ua los ntawm titanium alloy nrog epoxy resin hauv ob sab phlu, hnyav kwv yees li 2 grams, thiab muaj 12- hnub roj teeb. Cov ntaub ntawv muaj xws li pob zeb diamond, platinum, kub, thiab karat kub, nrog platinum PT950 ua ib qho kev xaiv nrov rau kab tshoob nplhaib vim nws hnav tsis kam. Kev hloov pauv ntawm cov khoom no nthuav tawm keeb kwm ntawm tib neeg kev vam meej: nyob rau hauv Egypt thaum ub nws tau ua lub cim ntawm lub hwj chim; nyob rau hauv ancient Greece, nws yog siv rau kev cai dab qhuas pe hawm; thiab nyob rau hauv 13th-xyoo pua Europe, kev sib pauv ntawm kab tshoob nplhaib tau dhau los ua ib feem ntawm kev ua koob tsheej.
