I am a big fan of the Senator collection. I already have the Perpetual Calendar, I obviously love the Senator Chronometer but I am curious to know fellow members options on these two reference. I know they are very different but yet I am draw to both of them. They both have a more sporty look then my Perpetual Calendar, have lume for night visibility. The Observer have a more vintage feel which I like and while it is 44mm at 12mm height it will also fit with a suit. I like the Chronograph panorama Date blue accent, the dial is a bit more modern, I could fit my current metal GO metal bracelet to it as well as it is also 42mm (like my perpetual) but wear a bit thicker at 14.6mm so might be more difficult with a suit but definitively a good casual sporty watch. I keep flip flopping between both reference. I know I want one of them (maybe both eventually) but I also notice very few members here seem to have the Chronograph while we see a bit more Observer...
