Is there any difference between Speedy Tuesday movement and Speedmaster Pro?

[djkennedy67]

I have a relatively new Speedmaster Pro, purchased from an a Omega dealer, and a Speedy Tuesday, purchased from a forum member.

They both feel different to manually wind and to set the time. The Tuesday feels light and flimsy whereas the Speedmaster Pro feels more robust and clicks over, when winding, with a more quality feel.

So, is there any difference between Speedy Tuesday movement and Speedmaster Pro?

I can’t think there would be, but would like to ask the experts if they know of any difference?

Many thanks in advance for your thoughts.
