Ploprof ... by 4 !

Mar 01, 2018,09:09 AM

The Omega Ploprof  is a mythic watch ... with this waterproof and specific case... A must !

Ploprof for"Plongeur Professionnel" ("professional diver" in english) or Seamaster 600m/2000ft  or ST166.0077. The watch was produced at the beginning of 70's.

A french meeting ... 4 models ... for an extraordinary group of Ploprof !

The weight for one model : near 200 grammes .... 
The proof :

Almost one kg, perfect for an infernal tower !

The first prototypes were made in titanium (10 models max) by the Schmitz Freres company. But the cost was so high that the titanium was replaced by steel...
Several watches were done for the Comex organisation (during oil exploration near Ajaccio by Elf Company) too.

Monobloc case (brevet 480.680 posted in 1967) for the best waterproof concept.
The mineral glass is pressed at 120 kg and maintened by a screw ring; and the screw crown is square and is maintened by a nut (brevet 503.310 posted in 1968) at 9 o'clock.

The watch was the watch of records. Waterproof to 600 meters !
By example, the watch was associated to the record of diving during Janus operation (-253 meters). And tests in laboratory demonstrate the waterproof resistance to -1370 meters ....

And now the pictures of the meeting :

During the 70's, different versions of dial were produced ... mk1, mk2, mk3...

The bezel is bidirectionnal and secured by the famous and specific red pusher  ...


Black or blue dials, multiple hands, multiple bezel's typography ... It is very difficult for the collectors to identity all the models ...

Isoframe strap, mesh or flightmaster band ... to discover by the caseback side  :

Two mk1 versions :

And a marvelous model with the pics and historic informations ...

And this model with this oiled black dial ...

To finish, a picture take by DrStrong during the report  ... Always with a mojito !

Best regards.

Great to see all theses PloProf all in one space. I am a big fan also but I can only match your with three. At least all the bases are covered. I need to put a report together. Bill Ps the ray was happily released. ...  

Bravo, Bill. That is such an achievement. Bring one with you, please.

Great pictures and it looks like the gathering was a lot of fun. Always great to spend time with some good watch buddies. I have always been intrigued by the PloProf. Just so much history and such a unique watch. I have always wanted to pull the trigger o... 

Watta stack!! . . .

 By: Dr No : December 7th, 2013-14:59
. . . usually, I find watches approaching this size to be unmanageable on my wrist, but the Ploprof is one notable exception. It's immense, no doubt about it, but . . . . . . the asymmetrical plinth-like case tends to subliminally minimize the impression ...  

Thanks for joining with the reissue Art...

The Polprof is much better for stacking than the Polaris! :) Best Blomman

The secret of Polaris stacking...

 By: DrStrong : December 14th, 2013-23:27
is like for big crowns...horizontal stacking ;-)

Agreed, a very risky game, with the Polaris. Couldn't stack more than 5.

And with a lot of fears! ;) Best, Nicolas
