Congratz!!!
A very nice Lemania "Omega" indeed!
RCAF cal 2221?
Apart from the bridges being signed Omega, the caliber designation 2221 (hacking 2220) and the serial numbers you will find is Lemania numbers, not Omega. These are true classics and of extreme quality. Rugged and reliable, and with some very cleverly designed features.
One of my all time favorite chronos!
Omega and Lemania had the same owners (SSHI), so when an Omega distributor gained a military chronograph contract, they could supply watches with dials with either brand names, or neutral like yours.
Here is my Lemania "brother".
