By Zenith
The Zenith Defy Revival ref. 03.A3648.670/21.M3648 is a brand-new 37mm stainless steel sports watch featuring a striking black dial with orange indices and a stainless steel bezel on a steel bracelet — a faithful reinterpretation of Zenith's legendary Defy lineage. The compact 37mm case makes it one of the most wearable entries in the Defy Revival collection, appealing to collectors and enthusiasts who value both heritage design and modern execution.
What sets this reference apart is the bold contrast between the black dial and vivid orange accents, a color combination that recalls the adventurous spirit of the original Defy from the late 1960s. Bizak & Co. is offering this piece brand new — contact us today or shop online to secure this Zenith Defy Revival at the best price available.
