Question to the PP experts
Need your advise: my brother came across a PP5170P Black dial with the diamond stick markers at his local dealer.
He is looking for that one Patek watch in his small collection and he quite likes the design of the watch.
Now designs come and go. For downside protection - in case he changes his opinion one day - what is the forum’s view on the watch vs alternatives (eg Datograph), future desirability and collectability of this model?
PS: I know it shouldn’t be directly relevant, but shortcutting the SS Daytona queue to a few weeks also comes with potentially purchasing this watch.

A slight correction if you don't mind
the 5170P comes with a blue dial which changes colour depending on the light. It is an amazing watch even with the discreet diamond markers. The fact that it will allow you to be fast tracked to a stainless steel Daytona is an added bonus (you must be from South East Asia!! 
) The Datograph has a lovely movement and its finishing is sublime. However, this watch is heavy so for me personally, it is not wearable. Your brother may prefer a watch which he can feel the weight in which case the Datograph would be fine. But my advice would be to try it on for size because it is 2mm larger than the 5170P and quite a bit thicker too. The 5170P is a lot more wearable in my opinion and it is interesting that this platinum Patek weighs less than a rose gold Datograph.

The Patek's RRP is significantly more than the Datograph despite the fact that the Datograph has a power reserve and the iconic large date. The resale value of Pateks in general tend to be better than their Lange equivalents.
I hope if your brother does get this lovely 5170P that you might end up with the steel Daytona!
I think 5170P is stunningly looking piece
in a high end price league,i doubt he really risking too much though i m not confident it sells quick for msrp in case he wants to flip it later on .btw You lose hefty sum on all ALS so the comparison you ve cited may not the best.
Watch to watch, I can't help with the personal preference, but if residual value is of concern I'd suggest with a fair degree of confidence that the PP is a better store of value (but by no means a wise investment!) [nt]

Similar retail prices I think for the 5170P and the Platinum Dato.
Very different watches as Sham has said. In my opinion you get a lot more with the Dato for the same money at retail price. However, to address your question, absolute dollar depreciation when buying at retail would be expected to be far higher for the Dato. Both however seem to trade poorly in the secondary market right now.
If you are concerned about depreciation then buy a preowned watch in mint condition. [nt]
