About the Omega Seamaster Ref. Ploprof600

The Omega Seamaster Ploprof 600, officially known as the Seamaster Professional 600m/2000ft, was developed for professional saturation divers. Its distinctive monobloc case design and robust construction set it apart from other Seamaster models of its era, emphasizing extreme water resistance and legibility under demanding conditions. This reference represents Omega's dedicated engineering effort to create a tool watch specifically for deep-sea work, distinguishing it from more general-purpose dive watches.

The watch features a substantial stainless steel monobloc case, designed to withstand significant pressure. It houses the Omega Caliber 1000 series automatic movement, known for its reliability. The crystal is a thick, flat mineral glass, chosen for its durability and resistance to pressure. The unique crown protection system and the prominent orange safety pusher for the bezel locking mechanism are key functional and aesthetic elements of its design.

For collectors, the Ploprof 600 is valued for its uncompromising tool watch aesthetic and its historical significance in professional diving equipment. It appeals to those interested in purpose-built timepieces and the evolution of dive watch technology. While not a mainstream design, its unique form factor and robust engineering make it a notable piece within Omega's heritage and the broader category of professional dive watches.

While there is no doubt about Mr. Christian Bonnici history.

I am very curious as to why the watch is mounted backwards or upside down if you will. The watch in that configuration is extremely bizarre. People have called them lefty but there is no evidence as such. Congratulations to the seller.

I've heard about requests being made by certain professionals for this configuration. But I'll need to check my source for that particular story! [nt]

It is usually done by mistake when watchmakers trry to mount as a classic watch with the crown at 3.

It is a 180 degree turn. But can require a change to the date wheel. It happened to me with a highly qualified watch maker who did not pay attention and the did replace the date wheel. I had it all reversed.

I'll check to see if that's what I'm recalling. [nt]
