The OMEGA Seamaster 120 Baby Ploprof Diver is a was ahead of its time in design & performance in 1978.
Its subtle black dial contrasts nicely with its oversized bezel & prominent hands. It's in uniform stainless steel & has retained its original manufactured parts.
Its mesh bracelet is a distinctive feature, which comes fitted with a seatbelt buckle: a latch is pushed into the clasp & secured with a lever!
GOOD-TO-KNOW: It's nicknamed "Baby Ploprof" by collectors because of its striking similarities with the Ploprof. Their dials, bezels, hands & bracelets are identical; while their case shapes & sizes are different. In other words, the Baby Ploprof is the subtle version of the beefed-up Ploprof. One is as valuable & desirable as the other.
