... as Rolex is my main focus in my collection, JLC and Omega also have a good place in my horological heart! 
In the Omega department, old chronos, diving watches Speedies and Constellation line are my main interest.
The Railmaster and Ranchero models are to watches I love but had been elusive to me. I hope I will finally get mine in a near future with a bit of luck!
You got a wonderful example of Railmaster there!!
Keep enjoying your collection my friend! Best cordial regards, Abel.
