Identification checklist

Check the dial, movement and case for Kienzle signatures or period logos. Compare movement caliber, case construction, dial printing and hand style with documented examples. On vintage pieces, inspect for refinished dials, replacement crowns and mixed movement or case parts.

Preservation guidance

Keep vintage watches dry and away from magnets and shocks. Do not wind or run a watch that is stiff, noisy or long unserviced. Have mechanical movements cleaned and lubricated by a qualified watchmaker; preserve original dials, hands, crowns and finishes whenever possible.
