The Quirky Backstory Of The Omega “PloProf”
Developed at the end of the 1960s and introduced in the early 1970s, the Omega Seamaster 600 was built with one purpose in mind: professional diving.
Its oversized asymmetrical case was therefore anything but a styling exercise.
The movement was loaded from the front into a massive monobloc steel case, while the crown was heavily protected on the left.
On the opposite side, the unmistakable red button had an essential job: the diving bezel couldn’t be rotated unless the button was pressed, preventing a potentially dangerous accidental change underwater.
And here’s where things get quirky.
During development, Omega’s Michel Geiger reportedly needed red plastic to machine prototype components for the bezel pusher and crown system. His solution? Buying toilet brushes with red plastic handles from Migros and using them as raw material. Swiss engineering sometimes requires Swiss supermarkets!
Rated to 600 metres and powered in production by the automatic calibre 1002, the original PloProf was unapologetically a piece of professional equipment.
