Vestal Gun, The ZR-3 is Vestal’s largest watch to date. If you’re BIG into retro style watches — this is your time to show it. The ZR-3 is an over-sized premium round chronograph. Its stainless steel case construction includes an extra thick raised crystal, seated in an angular fixed bezel. These design aspects, together with a crown guard and protective pusher design, add to its sophisticated yet retro styling. The ZR-3 is finished with a screw-down Vestal branded logo plate, vintage inspired three-link bracelet, and a premium butterfly deployant clasp.
