  • Original in all respects - dial, hands, case finish, insert, lume

  • Austral-asian model, Roman / English daywheel

  • 6138B movement fully serviced, timed and adjusted

  • All new seals

  • KVW 340W14GN00 Hardlex crystal

  • Case shows signs of wear but no abuse. Sharp case lines, intact brushing. Case has never been polished.

  • Lume glows but only for a short time. Some patina to the outer end of the minute hand lume.

  • Movement spring is upgraded to a heavier-duty type (custom made here) to hold the movement firmly
