Maybe you saw an old-timer....the PAM162.
"The PAM 162 was the first 44mm chronograph, but was relatively short-lived, only lasting a year, being supplanted by the white and black dial Slytech chronographs instead. The two Slytechs were originally promoted as having "panda" dials
, a la Newman Daytona
, however just before shipping this decision was vetoed, and they ended up as plain black or plain white. Perhaps the panda configuration is being saved for future special edition?"
