Born from Omega's legendary plongeuse professionelle lineage, the lacquered black dial and Grade 2 titanium construction of reference 227.90.55.21.01.001 represents the modern evolution of the iconic "PloProf" diving tool. This 48mm titanium case houses Omega's Master Chronometer Caliber 8912, delivering anti-magnetic resistance to 15,000 gauss while maintaining the collection's signature 1200-meter depth rating. The Seamaster Ploprof's distinctive asymmetrical case profile and integrated crown guard system preserve the original 1970s DNA while incorporating contemporary materials and movement technology. Omega Seamaster 227.90.55.21.01.001 arrives in unworn condition with both the titanium bracelet and supplementary black rubber diving strap.
