seems to me the "inverse/reverse" proplof is a myth, a result of servicing by someone who cant obtain the correct date disc for the 1660077
i still don't believe it cuz one can't operate the bezel (one handed) with the upside down config 👍
Actually, you can.....it’s quite easy, just tried both ways myself

I’ll take the information from Omegas online resource system for Watchmakers over a third party website any day.
I have access to the Omega extranet so I can see what you are saying, the Ref113ST1660077 is laser engraved for a 3 o'clock crown/date, having serviced a lot of the watches I am still not convinced, it would be interesting to see an extract for the case in question in the original post.
This is information directly from the Omega Extranet, their in-house computer reference system, I have an Omega authorised workshop....
'The Ploprof with case ref. 166.0077 exists in 2 versions. One with crown at 3 o’clock and one with crown at 9 o’clock.
The engraving in the caseback is the only reference point to tell which version you should have. The triangular OMEGA engraving is always facing up.'
Who came up with this information? It sounds like nonsense to me. If the museum don't have this information, then I find it unlikely that it is a reliable source on the extranet
Just to be clear the silver date wheel(and yellow for gold watches) that is orientated for crown at 3 o’clock is for many Omegas that use cal 1000 series movements, Devilles, Constellations, Seamasters etc.
The date wheel which allows the movement to have the crown positioned at 9 o’clock is only for the SM1000(cal1012) 166.093 and the Ploprof 166.077.
You could use that date wheel to create 'Destro' Seamaster 'shom' or baby Ploprof SM200, but I don't think any of these left the factory set up this way, neither do I believe the SM600 was built with the crown at 3o’clock.
As has been said it is much more difficult to use in this configuration on either wrist, so why would you do it?
As the standard Cal 1002 date wheel used on 99% of watches is not for the Ploprof, it makes perfect sense that when replaced watchmakers would order the wrong part and make the watch back up with the dial fitted upside down, possibly without even noticing the mistake.

Hi All,
It's been ages since I've had a good look around the forum so please excuse me if this has indeed been covered before...
The destro, or inverted Ploprof existed as a factory version, this is confirmed fact. J.Wallis Ploprof book is nice, but outdated source of info, theory about mad watchmakers inverting watches because lacking correct date wheels is busted myth .
I can confirm that in Omega extranet are both versions as was stated above and the inverted version can be recognized by orientation of the stamped triangle, the top points always to 12 o`clock.
Also here you have ref of the two data wheels: 1000-1580A - inverted version, crown at 3; 1000-1589A - normal ploprof version, crown at 9.
And because people believe only what they see, here you go:
