Marcello C. Classic Duochronograph Watch Vs. IWC Portuguese Chrono-Automatic Watch
Two great watches, two similar designs, and yet two vast different prices. Sizing up what over $10,000 extra will get you. The bilateral chronograph is a beautiful thing. Two registers placed along a vertical radius is classically appealing and high legible. In existence for over 60 years, this style has solidified itself as a true classic.The most notable watch to epitomize this style, at least in a modern sense is the IWC Portuguese Chrono-Automatic. A venerable monolith of classic proportions and design, it is pure legibility at its finest. The frills on the IWC are in the construction and the materials used. You can opt for a gold case, and the IWC movements are world class, as IWC has been one of the gold standards of pilot's watches for many decades. IWC backs up its watches with a reputation for refinement and reliability, but you certainly pay a premium for it. Once you settle on a watch design you like, there are often many options when it comes to satisfying your new taste.Ma

AP ROO vs Hublot
The AP ROO and Hublots seem very similar in design and price. Which is more desirable and why?

VERSUS: Submariner 1680 v. 16610
Had a random thought today to periodically start posting a VERSUS picture to compare two watches (and only those two watches) and discuss pros/cons by outlining the differences and getting folks' ideas/thoughts/opinions here. We got folks here who are experts that have been collecting and studying these things for decades to those who are just starting to venture into the crazy world of Rolex (and everyone in between). So I think it would be fun and educational!So to kick it off, I have for everyone today the iconic Submariner in the 'with date' variety. Reference 16610 v. 1680.Some obvious things:Glossy dial v. matteLuminova v. tritiumNon-maxi markers v. maxiWhich do you prefer and why?
