Sorry, my mistake, thought it was the day-date version of this watch...
Are you talking about the watch in this deal? I've never heard of a swiss manufacturer using a day-date movement in a date (no-day) watch.
No exhibition back but ETA 2836 movement.
I'll let you know when I get it!
Possibly, it appears the day-date variant has an exhibition case-back and is a 2836 but I can't find any much info on this model. It appears to have a solid steel back so I wonder if it might be one of their lesser Swissmatic movements.
