Maurice Lacroix Masterpiece Jours Retrogrades

I actually found these in my desk, I'm not sure where they came from and I don't remember them, but ah well!Neither of them work sadly, both could use some TLC. The gold one seems to be an older late 1800's, the white one maybe a teens-20's or even 30'sOne of the gears fell out when I opened it, can it be put back?Not much else I can say, I wonder what finish is on the silverish Elgin's Dial?........

Could someone please tell me to 'get a grip' and make me understand that I should not even be thinking about a bracelet on a new 5146? The rational part of my brain tells me that the watch on the leather strap is elegant, refined and beautiful, but the omega wearer (25 years) in me says that I would regret not having a bracelet on my daily-wearer. I know also that the sparkle from gold Patek bracelet is not even the same animal as a brushed steel omega bracelet and that I would regret it................
