Original black big red sigma dial in overall very good condition. The dial remains ultra bright and has some light aging to the subdials. The original hands have aged darker.

Excellent original case has been lightly polished in the past. The lugs remain thick and even. Original bezel, crystal, pushers and crown.

Excellent heavy oyster bracelet 78350/571 with minimal stretch.

This dial configuration was produced for a very short period, as a transition from the non-daytona sigma only dials into the later big red. This dial has both! Sigma big red are only found up to 5.2 serial and are actually quite rare. A classic and unusual daytona.
