Notes

Dial, case and movement signed. DIAM. 37 mm. THICKNESS 13 mm. Approx. overall length 185 mm. The Sigma dial variation of the famous and popular so-called 'BIG RED' DAYTONA is perhaps the rarest variant and was fitted with white gold batons instead of steel as indicated by the two symbols either side of the Swiss signature. It is generally accepted among collectors that the Big Red Daytona with Sigma dials were produced within the 4 million to 5.5 million serial number range; with 2 versions available, the MK1 produced from 4-5 million and MK2 within the 5-5.5 million serial. This example offered with 5.3 million serial features the MK2 Big Red Sigma dial. Property of a West Coast Collector
