Omega

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
