Excerpt: 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.
