The reference is defined by the use of a meteorite dial combined with an 18-carat yellow-gold case and bracelet. The watch is housed in a 41 mm case crafted from 18-carat yellow gold and is rated to 100 metres of water resistance. The case and bracelet follow the standard Chronomaster Sport architecture, with alternating brushed and polished surfaces and an integrated bracelet secured by a folding clasp.
