Because there are Chrono's and there are chrono's
By the way, they are not that expensive. If we take the 5070 you are talking about 2nd market high price due to the fact that its in very demand. The 5170 is IMO one of the finest chrono. You want an answer? The only way is to toy around with it. Check how the hand triggers, how its running, and the reset. Check the smoothness of the pushers... and take any other chrono and compare. There is a world of difference in those tiny details that only a watch lover will notice and will care for. If you do not have a general feel of excellence, than its all the same "more or less".
Chrono's are a very complex complication. People tend to forget it. They are made in huge numbers in movements like Valjoux, basic and raw. You will find it in a million watches, it works fine too. Does the job and thats it.
You are asking a good question though, to understand it you must go into details. What is the difference between a 500$ suit and 10'000$ tailor made one. Both are suits

A fiat Panda will take you from point A to point B, so will a Ferrari, as porsche's slogan says: "Its not about going from point A to point B, its how you get there" ... Or something like that.

I have wondered this too. The Daytona (also a chrono) carries a high price point in the Rolex range. People love chronos and the market seems to reflect the demand for them. The 5035 seems particularly under-valued, especially when measured against the mo...

Patek Philippe was the best made and best designed watch money could buy, and The Most Expensive. That was true, without argument by most, for many decades. The legend of the name became synonymous with The Best and Best Design, most Classic, Finest, and ...

true to some part, indeed. However, PP, unlike Breguet has not gone through bankruptcy and has been continuously making watches. Also, PP Lemania movements are seriously re-worked while Breguet Lemania movement is identical to Lemania movement used in a b...

I do not understand your arguments. Lange has not been continuously making watches either - does that mean Langes are no good? Breguet currently makes fine watches, notwithstanding any prior history, who their owners are, or any other irrelevant factors. ...

Surely Fricks' reply is only a part of the story. VC makes chronos easily as fine--commanding not nearly the price--forget LIST price--what do VC's really sell for new and used. Patek is a cherished illusion, a dream, and for a few, a reality that deliver...
just curious

I am just curious why are you disappointed with Patek? A Patek AC is about the same price as an AP Annual Calendar or VC Annual Calendar watch. So, why not choose the Patek. They are crazily expensive but so are these other brands, including Breguet.

patek has started to lose sight of the reality on the ground and what their timepieces should cost - regardless of the class of maufacture and quality of the workmanship, today i see many patek's offered at discounts and there are still no takers....i thi...
