Cartier Calibre De Cartier Black Dial Stainless Steel Men's Watch W7100061

PO Question for you all
My PO is my only automatic - my other 2 omegas are both quartz and i wear a citizen skyhawk A-T during the week. Because of this my PO isnt running all the time and I am wondering if this over time might cause undue wear and tear on it. IE: having to unscrew the crown once a week to set the time and wind it, Im also curious about what this inconsistent use might do the the movement - Will it over time affect its accuracy ( currently +3 sec a day )? Or could not using the watch all the time increase the service interval of the watch as it infact means the watch is used less.Any thoughts, opinions, facts are greatly appreciated.

SS DeVille Co-Axial Chronometer
I was set on getting a Datejust II and walked past an Omega AD when this watch caught my eye. I brought my wife in and she picked herself a DeVille Prestige co-axial with a mother of pearl face. Both watches are all stainless and I think are a pretty classical design. I've done some post purchase searching and find absolutely nothing on these watches. Did I just buy two dead models or are we just that much ahead of the curve?

Speedtona
After 13 years of Daytona ownership, I was recently bitten by the Speedy Pro while on vacation. The biggest positive for the Omega over the Rolex (other than price)? One word: LEGIBILITY. The Daytona's highly polished hands and tachymeter bezel are terrible for low light situations they basically turn black and disappear without reorienting the viewing angle.As this picture shows - I've always been a sucker for a balanced subdial layout. The Bucherer dates from about 1974 and I wore it from high school through college.

Help with Trade on collection
Hello Again everyone I need some advice!!! So I've been refining my collection I got rid of my Omegas and I sold my old 5711 to fund a brand new 5711 blue dial from an AD as they finally got one in so papers are in my name. Anyways I need help because while I was looking in the dealer I realized although I'm a huge watch enthusiast that likes a variety of brands Patek seems to really make everything else I try on not so satisfying. Now I have two questions that I need advice on what to do to well round my collection. So my currently I stand with these beautiful watches: A Rolex Milgauss White dial, A Rolex Blnr, a Rolex 116520 Daytona, an Ap 15202 white dial 2014 dated so hard to find a late model white dial and of course last but not least my Patek 5711 blue dial. The two watches that really got me moving was A Patek Philippe 5726/a on a leather strap and a Patek Philippe 5960/1a just really was a stunner. So I'm to the point now that for a short period of time I'm not comfortable buy
