There's Original and there's ALL original...
You should not be TOO hard pressed as a collector to pick up a "Baby ProPlof" there's a few out there, however, unfortunately, most of these are not exactly what they seem on the surface, Most are built of original Omega parts but few of these watches left the factory as complete assembled watches in the 70s ...
Most of the Ref. 166.0250 available today are "built up" of ether NOS parts from the 70s or in the worst case scenarios all completely assembled from service (replacement) parts, New cases New Dials New Movements, Hands etc... Even Many of the seemingly correct examples on the market today have a replacement element rogued in there somewhere.

Above Right: A Rare example of an ALL ORIGINAL 120 all parts correct and original 1978 omega a complete collectors watch
To the discerning collector these should not be too hard to spot, but unfortunately, many of the watches that do come to public market are incorrectly marketed as "vintage" when in reality they are (in the most critical eye) not much more than "homage" watches and at best uncertified Omega "re-editions"
The ProPlof's baby brother.
The ST 166.0250 takes its collector's nickname nome the Dady of Omega dive watches,
"ProPlof" is the portmanteau (the blending of the two words) plongée & profeshionale
Some have described the Proplof as "the ugliest watch omega ever made" I for one disagree (google search the Omega "Quadra" for a vomit inducing and short-lived lived line from Omega)
Now some may wear the watch for its impressive diving credentials others for its striking look.
Diving Legend and all round superhero Jacque Custeau was partial to the ProPlof as well as a plethora of other marine Omegas,
Giovanni "Gianni" Agnelli, also known as L'Avvocato, an influential Italian industrialist and all round "Style Icon" was often pictured with his trademark over the cuff look sporting a ProPlof more for style one would presume than practicality
Whatever your thoughts on the ProPlof, its little brother the 166.0250 has clearly inherited all the looks and none of the "bulk"
By no means small tho, not by vintage standards, still a watch more than capable of holding its own in a world of often needlessly oversized modern divers watches.
38.5mm in diameter excluding the XL yet partially integrated crown 42.65mm inclusive,
42mm lug tip to lug tip. 22mm lug spacing
Its a chunky looking masculine watch but at a deceptively slim 11mm tall a seriously comfortable skin diver tool watch.
One of my all-time favourite design features on not just this but a lot of vintage tool watches of the later 60s and 70s period are those super cool "hooded" or hidden lugs giving any strap attached an "incorporated" look
Original Sprung locking XL Omega Signed Ω crown and screw affixed case back by design give the watch its excellent waterproofing credentials.
A 60 click Mono-Directional bezel a classic Count up divers bezels with YUP original Tritium bakelite insert, again none of that later Watchco crap here =).
Matte Black Stunning natural age patina Heavy Tritium indexes. ProPlof Broad Arrow "Stick" hands synonymous with Omega divers watches. White square tipped centre sweep seconds hand. Again all creamy aged tritium all original. Date aperture at 3
All other detail in crisp white
The watch is fitted with a genuine vintage tropic type 22mm basket weave rubber watch strap with swiss Acier buckle
A Seriously good condition movement again all Original all deep rose gold plated no evidence of over or incorrect servicing no rotor wear at all good centre pinion and all fully operational.
f = 28800 A/h
power reserve 42h
Originally Produced between 1972-1984
The automatic gear is integrated into the movement, instead of attaching it to a manual-wind calibre as usual.
Together with an indirectly driven minute and second this leaves in the centre space for a rugged rotor bearing, despite the low profile.
