Available in two versions, the Elemental and the Two Timer (single and dual time zones, respectively), the Biformeter uses an ETA 2892/ 2893 mechanical automatic movement with a 42 hour power reserve. The Biformeter is available in 316L stainless steel or 18K gold and is fitted with a unidirectional bezel suitable for dive timing and each piece features a screw-in back and crown for optimal water resistance to 300m and it is rigorously tested to ensure shock resistance, accuracy and reliability. The Biformeter Two Timer in gold is available in two models. One is entirely sculpted in 18K yellow gold while the other combines 18K yellow gold with an aluminium bezel in either black or red – with a matching dial and aluminium back case covering.
