The 5177 watch is among those models steeped in the classicism and tradition of which only Breguet holds the secret. Formerly existing only in 18-carat yellow and white gold, it is now being introduced in a red gold version. Newly clad in this warm-toned precious substance, it naturally preserves all of the sophisticated elements expected in a timepiece from the Breguet Classique collection: a fluted case middle with a transparent back; soldered strap lugs; a silvered solid-gold dial that is available with hand-engraved guilloché in a cross weave motif or in grand feu enamel; and blued steel Breguet hands decorated with the characteristic “eccentric moon tip.”
