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.

Hello everyone. Can anyone help me. I have an invicta tria watch model 19426. The movement is Ronda 8040n with date at 9. The watch is currently not working and movement needs to be changed.

You probably can’t find that anywhere and will have to send it back to Invicta to repair, or find one cheap for parts. You can also just get another 8040N and try to take your datewheel from your broken one and put it on the new movement. It’s… Read more »

First of all thank you so much for responding to my post. Actually I am from india and have bought the watch online from eBay.com. there is no watch maker in my country who can swap the date wheel for me. I tried to swap but after that the date advances from 1 to 9 but after that it does not advance to 10. Again I can manually change the date wheel with stem position at one click, that is with the stem at date adjustment position it works absolutely fine but with stem at 2nd click that is time… Read more »

Sumit, something is stopping it from hitting the 0 number of the second digit. This is odd sounding. Did you say you already got another 8040N and tried to swap the date wheel yourself so that you can use a new 8040N but with the old datewheel? Do you have any pictures of what you’re working on?
