About a year ago, I decided to change the bracelet on my Omega Seamaster 300 M Chronograph Professional into the rubber strap. What did I find? Well there were 2 holes on each lugs. Now that is something I have not seen before. There were only 1 hole on the lug on my Seamaster 300 M Professional.
I posted and asked on an Omega forum and could not get a conclusive answer. Why were there 2 holes on the lugs? Was there an error? Did the watch get passed over during the quality check?
My watch the Omega 300 M Chrono Diver from 1996, Model No. 2225.
The holes on the lugs. Note there are 2 holes per lug.
The 'star' on the lug is an Omega internal production monitoring system to mark watches that has had some work done on it. On my watch, according to Omega, it has had a new generation winding stem tube installed (new generation back in 1996).
Anyway this was always troubling me, but I put it on the back burner. Until a couple of days ago, when I was at my friendly neighbourhood watch guy. He was about to take apart an Omega Seamaster Professional 300 M Chrono. This is the newer model, Model No. 2594. Guess what? It had 2 holes on the lugs as well.
So I figure, the holes is there to accommodate different straps for the watch. One set of holes for the metal bracelet, and the other maybe for the rubber. I am still guessing here. I guess I could write to Omega and ask. We will see....
