Hesalite is my dream material :-)
Thankyou for bringing this very interesting topic to our knowledge

Vintage Omega Seamaster and Speedmaster "plexy" (how to date them)
First of all sorry if I'm boring you with such things that you already know. I'm trying to realize an Omega topic based on Speedmaster and Seamaster plexy. There are different kinds of logo on the omega plexy based on which you can determine if it is corr...

mstanga, just to put the cat amongst the pigeons, i have two speedmasters that are less than five years old, both of which have your "old style" logo on the crystal. regards,simon.
Ok but...
Ciao Simon, thank you for your answer. Would You be so kind to post a photo of these logo? You have to pay attention to the dimension of the omega logo, it must be narrow for the old ones, and wide for the new one. One thing we can say for sure: On speedm...
An other shape of Omega vintage logo
Thanks mstango for this thread. And i noticed that there exist an other type of Omega logo : (is like the first one (omega straight legs) but with longer legs). I have a picture, but it's not a very good one ! (although we sense the shape) : It's from an ...
