As a further tribute to this peaceful use of wartime technology, OMEGA has produced two models cased in 950 platinum, each limited to just 70 pieces. In keeping with the luxury finish, the Master Chronometer movements include an 18K Sedna™ gold rotor and balance bridge. Adding even more shine to the classic post-war design are hands in 18K Sedna™ gold or 18K yellow gold - depending on the model.
