Certina DS-2 Chronograph Stainless Steel C024.447.11.081.00

The name goes back to 1968, when, in Certina's words, the original DS-2 established new benchmarks for resistance; the current DS-2 line dates from 2013. DS stands for Double Security, the idea Certina developed under Hans and Edwin Kurth in 1959 of suspending the movement inside a reinforced case.

Among the chronographs, the C024.447.44.051.00 has a black dial, and the two-tone C024.447.22.051.00 (black) and C024.447.26.031.00 (silver) keep the 41 mm case and tachymeter. The Chrono 1/100 Sec PreciDrive references, such as the Inverted Panda C0244471105100, share the 41 mm diameter but are slimmer at 12.45 mm against this watch's 12.95 mm. The Chronograph Flyback (C024.618.11.051.01) moves up to 43 mm. Without the chronograph, the DS-2 Quartz has a 40 mm case about 9.3 mm thick, as on the grey-dial C024.410.11.081.20.
