you can bet on it, every post about a 5070 is a post I read several times ;-)
As for the looks, everybody has his own favorites, while I'll prefer the 5070 by far, I'm sure others will prefer the 5170. I also had the chance to 'play' with the 5170 some time ago and I confess, it is great and the pushers are very smooth. Is it better in a technical point of view ? Probably.
I mean, when BMW updates the 5-series people also expect the the newer 5-series will be a bit better than the older 5-series. Why else would the make a new car. But is the most modern and therefore probably the best the most interesting ? Let me choose between a new Jaguar and a XK120 from decades ago.... I'll take the XK120 in a heartbeat. Even when I know the new is probalby the most reliable and the most comfortable.
That said, the only thing I don't like about the 5170 is the price. Today is is twice the price of a 5070 5 years ago. I could accept 30% due to the CHF , gold and inflation ... but 100% more.... ouch ...
I love Patek and it will always be the brand I worship the most but when I look at their prices today, they're not for me anymore. 5 years ago I could convince myself to save, save and save and sell a few other watches to obtain a Patek I really , really love. Today selling other watches and saving still won't be enough. I'm forced to look at others (read cheaper)
Ofcourse others buy these watches as easy as I would buy a Swatch, and I'm glad these people share their feelings about these watches with us. But for me they're priced out of the market, my market
