Daytona 6238 transitional blueish rare dial - Full steel, silver-blue dial, "arrow head" indexes, chronograph, 3 counters, minute track, steel bezel, unscrewed pushers, small second hand, mechanical movement. 72 B caliber. Introduced in 1960 and demarking itself from the older non-oyster Rolex Chronographs, its pure, modern design makes it a milestone in the genesis of the Daytona; the main difference between a late 6238 and and early Daytona are the smooth bezel and the dial that has no constrasting registers, but instead features a plain silver or black dial (or gold). A very understated but modern piece of design.
