HUGE congrats, my friend!

This is a theme we (and many other Purists) love and share!

As for the Cal 501 vs Cal 552 - as you know I am not a Omega expert, but some of the differances I suspect (based on that the 552 is the same base caliber as 551):

The diameter is not the same - the 501 is 28.50mm while the 552 is 28.40mm.

The bridges - 501 has separate brigde for barrel and center wheel while the 552 has combined barrel and centerwheel bridge.

In total the 501 has 7 bridges while the 552 has 6 bridges.

The 501 use 14 jewels for the gear-train while the 552 use 19...

But as I said - I am far from an expert.

As always - such a wonderful post, my friend!

Here is a later sister (2913-7) saying hello!
