A nuanced take on the Ingenieur SL, reference 3003 brings Gerald Genta's integrated design into a warmer register with a 38mm stainless steel and yellow gold case. The black dial keeps the look disciplined and legible, giving the mixed-metal architecture the right contrast. Inside is an automatic movement with date. At 12.5mm thick, it wears with the compact, purposeful stance collectors want from an early Ingenieur SL.
