This is a very cool looking movement with the grande date and the retrograde day of the week. I am glad to see that Wing is now using this movement in his Aragon watches. I will have to check those out. I thinkers the Invicta Excursion is a great looking watch. I’m a sucker for the “mirror polished” look and have an Aragon with that high polished look. I believe it is my favorite watch

This movement is used in the Ruf Pilot Sport 48mm. Haven’t received mine as of this post but aesthetically it is very similar to the iconic IWC Big Pilot and nearly as beautiful.
