The new series also includes four new solar chronographs powered by Caliber V192. The case shape is faithful to the original but its 39mm diameter, the combination of hairline and smooth polishing on the bracelet and the curved sapphire glass bring it right up to date. These new solar chronographs are offered in four different dial colors; white, navy, gold and black. Their dials have a sandblast finish which ensures the high level of legibility that is a core characteristic of every Prospex watch. All four watches will also join the main Prospex collection.
