Ronstan V2 Clear Start Watch, 50mm, Black (RF4055A)

SKU:  RF4055A

Brief Description:

The new RF4055 ClearStart™ watches are a completely new design with an updated contemporary style and new materials, alongside all the familiar timing features and functionality that define the ClearStart™ range.



  • Lens is now ultra-clear, scratch resistant mineral crystal, recessed for extra protection.
  • Case is now glass-reinforced polycarbonate with stainless steel structural tension ring around the hardened crystal lens, resulting in an exceptionally stiff construction.
  • Band is now injection-moulded in a soft-feel silicon for added resilience, flexibility and comfort.
  • Nylon reinforcements embedded in the band add strength at stress points.
  • Buttons are shaped to a lower profile to avoid accidental activation.
  • Buttons act on precision stainless push rods, sealed with triple gaskets in stainless tubes within the watch case to prevent moisture entry.
  • Available in Red (RF4055), Black (RF4055A) and Blue (RF4055B).
