Omega

Still unsure about meaning of "pre-rg".

Dear Bill

This is a very interesting tread for me, but I have this odd feeling, that  something is pasing way above my head.

I asked why the watch you showed is called "Pre-rg", and since the movement to my eye looks like any early 30 mm, I thought it had to do with the layout of the dial.

Later Art (Dr.No) answers, that the distingshion is " due to the regulator . . .".  How is the regulator different ?

Yours

hey.... ok Pre-Rg.... vs Rg

Hello Arkona44

The watch I previously posted in a early 30 mm chronometre from 1941.   The 30T2Rg with the Omega system regulator was release in 1943.   I have always referred to the 30T2 chronometre grade as a Pre-Rg chronometre due to the fact the Rg was not yet release. 

These early Pre-Rg chronometres display a lot of the same types of higher end finishes that the later 30T2Rg have but ever so slightly different. 

As an example the winding wheels of both the Pre-Rg and the Rg are high finished but they are done almost in opposing styles to each other... 
The most notable difference ( not counting the nickel plating vs rose gold color plating)  is the regulating system the Pre-Rg has a simple stick regulator while the 30T2Rg has an index regulating system ( Rg=index regulation ) is the screwhead based Omega system. 

Here is a standard 30 mm Omega movement.... notice the finish of the wheels , not polished just stamped flat parts .  They are finished to the level needed to get the job done !

Here is my  Pre-Rg 




an Ad for the 30MM Rg chronometre


Here is a typical 30T2SCRg



and as a finishing touch .... after Omega stopped producing the 30T2SCRg..... to the genreal public they never produced a later 30 mm movement with index regulation....  ( that is not true).... 

Here before you is a uncommon cal 283Rg  ( I added the Rg designation to the cal reference,  an Rg stands for index regulation) .  Here you see an uncommon Factory Modification of a caliber 283 with a swan neck regulator and balance cock!




I wanted to spark your interest on these great time pieces...


Good Hunting

Hi Bill,

You totally misunderstood my post in this thread!

My response was concerning the watch shown by Jacob, not your´s...

Your watch is delicious and I know the importance of this piece - I have one in my collection too (as you might know...).

kind regards

erich

Hi Erich


I did not mean to be hard edge... just beauty is in the eye of the beholder.  I did not mean any disrespect to you I just viewed my watch differently.   I am also sorry I misread your post.   Welcome to the global village were everyone first language is not English ! 

I am the typical american that can only speak one language , please accept my apologies or that. 

I would love to see your "Pre-Rg" 30 mm chronometre.


Best regards
