The ref. 5172G-001 in a new white gold case with rounded guilloched pushers and three-tier lugs also has an updated column wheel, horizontal clutch, and manual winding chronograph. Emphasizing its understated vintage appeal is the sapphire-crystal "box" glass. Its dial has a completely new look with a blue backdrop with luminescent white gold hands and Arabic numerals that contrast.
