What little detail can change the overall vibe from dressy to sporty? Putting a center-second vs. a sub-second dial layout next to each other and you will immediately see how the appearance of otherwise identical timepieces will change. This is the topic of the third edition of my Patek Philippe Calatrava guide - a list that's meant to educate and get the community involved.

Patek Philippe is mainly known fro its extremely elegant and timeless designs. But what little detail can change the overall vibe from dressy to sporty? Putting a center-second vs. a sub-second dial layout next to each other and you will immediately see how the appearance of otherwise identical timepieces will change.

Here, I'll try to lay the foundation for a community driven database for the rare, the rarely seen and the rarely remembered timepieces that do not get the attention that other pieces might get. I'd be more than happy for everyone who sees him/herself fit to share and to add information about what we love - vintage watches. This is not an exhaustive list, yet(!) but I want it to become a central resource for everyone finding their way into vintage watches, from novice to expert.

This is the third edition for the Patek Philippe time-only (Calatrava in a loose definition) timepieces. So enjoy the eye candy and hopefully you can learn a thing or two about what makes these pieces so special, rare and sought after.
