I have been in collecting the 30mm movements long time ago. From the 30, 30T1, T2 and then the 26X and 28X.. I have not counted them yet but I guess I have more than 50 of them in my collection.
In the next few days, I will try to post some photos of these legendary movements and watches that were powered by this family.\
If you have the same interest, please join and share your pics.



the legendary 30SCT2Rg



which came from the 30mm



and then the 30T1SC





with only 2400 pieces made.

the 30T2



and 30T2SC



that powered the US Army 2179



the Suveran



the 30T2Rg

 

Any one of those three will work for me. How many points do I need to redeem?

 

I love a good Cal 30mm. This is a 1954 266, which I serviced yesterday.


























Such a simple, beautiful, calibre.

 

Being an amateur I don't rush I guess I spent about 3 hours on this one. That includes taking photos, spending some time trying to find the new 30T mainsprings I bought and stashed somewhere stupid. I still haven't found them - but I did find a bonus spare 30T spring I didn't know I had , so problem solved for this one.

The cleaning machine made a huge difference to the time it takes me to do a movement... Its like air conditioning, you don't need it - but boy are you ever glad you have it.

 

The 30 and 30T1 were finished with perlage on dial side, the area that nobody will see except the watchmaker



not too long after that, the movements were plated in rosegold color




Normally, they have 15, 16 or 17jewels but sometimes, you can find the rare 18 jewels in case ref 2254





the 2423 (2410)



or the Royal Canadian Air Force

 

Simon Freese just released this super video about the 30mm Omegas as part of his £100 to Rolex series.
As a relative newbie I now feel I should be on the look-out for one or two nice examples as my small collection of vintage Omegas are all cal 5xx.

What would be your 30mm of choice?
