Dial, case and movement signed. DIAM. 36 mm. THICKNESS 14 mm. Rolex obviously still experimenting with dial layouts and the use of the proper name for the sporty chronograph has resulted in these early pre-daytonas, so called Solo Rolex. Featuring only the name of the brand on the dial, this has cleaned up the dial totally and left it pure and simple. Also found on the reference 6240 where Rolex was already experimenting its next phase of chronographs featuring the plastic bezel and screw-down pushers, these watches are now considered the real start of the Daytona legacy.
